3 Our solutions. Reactive energy management In electrical networks, reactive energy results in increased line currents for a given active energy transmitted to loads. The main consequences are: Need for oversizing of transmission and distribution networks by utilities, Increased voltage drops and sags along the distribution lines, Additional power losses. This results in increased electricity bills for industrial customers because of: Penalties applied by most utilities on reactive energy, Increased overall kva demand, Increased energy consumption within the installations. Reactive energy management aims to optimize your electrical installation by reducing energy consumption, and to improve power availability. Total CO 2 emissions are also reduced.

4 Improve electrical networks and reduce energy costs Power Factor Correction Every electric machine needs active power (kw) and reactive power (kvar) to operate. The power rating of the installation in kva is the combination of both: (kva)² = (kw)² + (kvar)². The Power Factor has been defined as the ratio of active power (kw) to apparent power (kva). Power Factor = (kw) / (kva). The objective of Reactive Energy management is improvement of Power Factor, or Power Factor Correction. This is typically achieved by producing reactive energy close to the consuming loads, through connection of capacitor banks to the network. IV

12 Power Factor Correction guideline Why reactive energy management? Principle of reactive energy management + Due to this higher supplied current, the circulation of reactive energy in distribution networks results in: > Overload of transformers > Higher temperature rise in power cables > Additional losses > Large voltage drops > Higher energy consumption and cost > Less distributed active power. DE90087.eps In this representation, the Power Factor (P/S) is equal to cosj. DE90071_r.eps All AC electrical networks consume two types of power: active power (kw) and reactive power (kvar): The active power P (in kw) is the real power transmitted to loads such as motors, lamps, heaters, computers, etc. The electrical active power is transformed into mechanical power, heat or light. The reactive power Q (in kvar) is used only to power the magnetic circuits of machines, motors and transformers. The apparent power S (in kva) is the vector combination of active and reactive power. The circulation of reactive power in the electrical network has major technical and economic consequences. For the same active power P, a higher reactive power means a higher apparent power, and thus a higher current must be supplied. The circulation of active power over time results in active energy (in kwh). The circulation of reactive power over time results in reactive energy (kvarh). In an electrical circuit, the reactive energy is supplied in addition to the active energy. Power generation Active energy Reactive energy Transmission network Reactive energy supplied and billed by the energy provider. Active energy Reactive energy Motor DE90088.eps Q Q c For these reasons, there is a great advantage in generating reactive energy at the load level in order to prevent the unnecessary circulation of current in the network. This is what is known as power factor correction. This is obtained by the connection of capacitors, which produce reactive energy in opposition to the energy absorbed by loads such as motors. The result is a reduced apparent power, and an improved power factor P/S as illustrated in the diagram opposite. The power generation and transmission networks are partially relieved, reducing power losses and making additional transmission capacity available. DE90071_r.eps Power generation Active energy Transmission network Active energy Reactive energy Motor The reactive power is supplied by capacitors. No billing of reactive power by the energy supplier. Capacitors 4
13 Why reactive energy management? + Benefits of reactive energy management Optimized management of reactive energy brings economic and technical advantages. Savings on the electricity bill > Eliminating penalties on reactive energy and decreasing kva demand. > Reducing power losses generated in the transformers and conductors of the installation. Example: Loss reduction in a 630 kva transformer PW = 6,500 W with an initial Power Factor = 0.7. With power factor correction, we obtain a final Power Factor = The losses become: 3,316 W, i.e. a reduction of 49 %. Increasing available power A high power factor optimizes an electrical installation by allowing better use of the components. The power available at the secondary of a MV/LV transformer can therefore be increased by fitting power factor correction equipment on the low voltage side. The table opposite shows the increased available power at the transformer output through improvement of the Power Factor from 0.7 to 1. Power factor Increased available power % % % % % % Reducing installation size Installing power factor correction equipment allows conductor cross-section to be reduced, since less current is absorbed by the compensated installation for the same active power. The opposite table shows the multiplying factor for the conductor cross-section with different power factor values. Power factor Cable crosssection multiplying factor Reducing voltage drops in the installation Installing capacitors allows voltage drops to be reduced upstream of the point where the power factor correction device is connected. This prevents overloading of the network and reduces harmonics, so that you will not have to overrate your installation. 5
14 Power Factor Correction guideline Method for determining compensation The selection of Power Factor Correction equipment can follow a 4-step process: Calculation of the required reactive energy. Selection of the compensation mode: - Central, for the complete installation - By sector - For individual loads, such as large motors. Selection of the compensation type: - Fixed, by connection of a fixed-value capacitor bank; - Automatic, by connection of a different number of steps, allowing adjustment of the reactive energy to the required value; - Dynamic, for compensation of highly fluctuating loads. Allowance for operating conditions and harmonics. Step 1: Calculation of the required reactive power DE90091.eps The objective is to determine the required reactive power Q c (kvar) to be installed, in order to improve the power factor cos φ and reduce the apparent power S. For φ < φ, we obtain: cos φ > cos φ and tan φ < tan φ. This is illustrated in the diagram opposite. Qc can be determined from the formula Qc = P. (tan φ - tan φ ), which is deduced from the diagram. Q c = power of the capacitor bank in kvar. P = active power of the load in kw. tan φ = tangent of phase shift angle before compensation. tan φ = tangent of phase shift angle after compensation. The parameters φ and tan φ can be obtained from billing data, or from direct measurement in the installation. The following table can be used for direct determination. Before compensation Reactive power (kvar) to be installed per kw of load, in order to get the required cos j or tan j tan j cos j tan j cos j Example: consider a 1000 kw motor with cos j = 0.8 (tan j = 0.75). In order to obtain cos j = 0.95, it is necessary to install a capacitor bank with a reactive power equal to k x P, i.e.: Qc = 0.42 x 1000 = 420 kvar. 6
15 Method for determining compensation Step 2: Selection of the compensation mode Supply Bus Transformer Circuit breaker The location of low-voltage capacitors in an installation constitutes the mode of compensation, which may be central (one location for the entire installation), by sector (section-by-section), at load level, or some combination of the latter two. In principle, the ideal compensation is applied at a point of consumption and at the level required at any moment in time. In practice, technical and economic factors govern the choice. IC CC GC GC IC IC IC The location for connection of capacitor banks in the electrical network is determined by: th e overall objective (avoid penalties on reactive energy relieve transformer or cables, avoid voltage drops and sags) the operating mode (stable or fluctuating loads) the foreseeable influence of capacitors on the network characteristics the installation cost. M M M M CC : Central Compensation GC : Group Compensation IC : Individual Compensation M : Motor Load Central compensation The capacitor bank is connected at the head of the installation to be compensated in order to provide reactive energy for the whole installation. This configuration is convenient for a stable and continuous load factor. Group compensation (by sector) The capacitor bank is connected at the head of the feeders supplying one particular sector to be compensated. This configuration is convenient for a large installation, with workshops having different load factors. Compensation of individual loads The capacitor bank is connected right at the inductive load terminals (especially large motors). This configuration is very appropriate when the load power is significant compared to the subscribed power. This is the ideal technical configuration, as the reactive energy is produced exactly where it is needed, and adjusted to the demand. 7
16 Power Factor Correction guideline Method for determining compensation Step 3: Selection of the compensation type Different types of compensation should be adopted depending on the performance requirements and complexity of control: Fixed, by connection of a fixed-value capacitor bank Automatic, by connection of a different number of steps, allowing adjustment of the reactive energy to the required value Dynamic, for compensation of highly fluctuating loads. Fixed compensation This arrangement uses one or more capacitor(s) to provide a constant level of compensation. Control may be: Manual: by circuit-breaker or load-break switch Semi-automatic: by contactor Direct connection to an appliance and switched with it. These capacitors are installed: At the terminals of inductive loads (mainly motors) At busbars supplying numerous small motors and inductive appliances for which individual compensation would be too costly In cases where the load factor is reasonably constant. Automatic compensation This kind of compensation provides automatic control and adapts the quantity of reactive power to the variations of the installation in order to maintain the targeted cos j. The equipment is installed at points in an installation where the active-power and/or reactive-power variations are relatively large, for example: on the busbars of a main distribution switchboard on the terminals of a heavily-loaded feeder cable. Where the kvar rating of the capacitors is less than or equal to 15 % of the power supply transformer rating, a fixed value of compensation is appropriate. Above the 15 % level, it is advisable to install an automatically-controlled capacitor bank. Control is usually provided by an electronic device (Power Factor Controller) which monitors the actual power factor and orders the connection or disconnection of capacitors in order to obtain the targeted power factor. The reactive energy is thus controlled by steps. In addition, the Power Factor Controller provides information on the network characteristics (voltage amplitude and distortion, power factor, actual active and reactive power ) and equipment status. Alarm signals are transmitted in case of malfunction. Connection is usually provided by contactors. For compensation of highly fluctuating loads use of active filters or Electronic Var Compensators(EVC) are recommened. Contact Schneider Electric for electronic compensation solutions. Dynamic compensation This kind of compensation is required when fluctuating loads are present, and voltage fluctuations have to be prevented. The principle of dynamic compensation is to associate a fixed capacitor bank and an electronic var compensator, providing either leading or lagging reactive currents. The result is continuously varying fast compensation, perfectly suitable for loads such as lifts, crushers, spot welding, etc. 8
17 Method for determining compensation + To know more about the influence of harmonics in electrical installations, see appendix page 66 Step 4: Allowing for operating conditions and harmonics Capacitors should be selected depending on the working conditions expected during their lifetime. Allowing for operating conditions The operating conditions have a great influence on the life expectancy of capacitors. The following parameters should be taken into account: Ambient Temperature ( C) Expected over-current, related to voltage disturbances, including maximum sustained overvoltage Maximum number of switching operations/year Required life expectancy. Allowing for harmonics Depending on the magnitude of harmonics in the network, different configurations should be adopted. Standard capacitors: when no significant non-linear loads are present. Harmonic rated capacitors used with detuned reactors. Applicable when a significant number of non-linear loads are present. Reactors are necessary in order to prevent the amplification of harmonic currents and avoid resonance. Active filters: when non-linear loads are predominant, use of active filters are recommended for harmonic mitigation. Solutions can be recommended based on computer simulations or on site measurement of the network. Capacitor selection Different ranges with different levels of ruggedness are proposed: "EasyCan": Capacitors for standard operating conditions, and when no significant non-linear loads are present. "VarPlus Can & Box": Capacitors for stringent operating conditions, particularly voltage disturbances, or when a few non-linear loads are present. The rated current of capacitors must be increased in order to cope with the circulation of harmonic currents. "VarPlus Box Energy": Specially designed capacitors, for harsh operating conditions, particularly high temperature. Capacitors with detuned reactors: applicable when a significant number of non-linear loads are present. Before After 9
18 Power Factor Correction guideline Low Voltage capacitors with detuned reactors Capacitors and reactors are configured in a series resonant circuit, tuned so that the series resonant frequency is below the lowest harmonic frequency present in the system Reactors should be associated with capacitor banks for Power Factor Correction in systems with significant non-linear loads, generating harmonics. Capacitors and reactors are configured in a series resonant circuit, tuned so that the series resonant frequency is below the lowest harmonic frequency present in the system. For this reason, this configuration is usually called Detuned Capacitor Bank, and the reactors are referred to as Detuned Reactors. The use of detuned reactors thus prevents harmonic resonance problems, avoids the risk of overloading the capacitors and helps reduce voltage harmonic distortion in the network. The tuning frequency can be expressed by the relative impedance of the reactor (in %), or by the tuning order, or directly in Hz. The most common values of relative impedance are 5.7, 7 and 14 % (14 % is used with high level of 3rd harmonic voltages). Relative impedance (%) Tuning order Tuning 0Hz (Hz) Tuning 60Hz (Hz) The selection of the tuning frequency of the reactor capacitor depends on several factors: Presence of zero-sequence harmonics (3, 9, ) Need for reduction of the harmonic distortion level Optimization of the capacitor and reactor components Frequency of ripple control system if any. To prevent disturbances of the remote control installation, the tuning frequency should be selected at a lower value than the ripple control frequency. In a detuned filter application, the voltage across the capacitors is higher than the system s rated voltage. In that case, capacitors should be designed to withstand higher voltages. Depending on the selected tuning frequency, part of the harmonic currents is absorbed by the detuned capacitor bank. In that case, capacitors should be designed to withstand higher currents, combining fundamental and harmonic currents. Effective reactive energy In the pages relating to detuned capacitor banks, the reactive energy (kvar) given in the tables is the resulting reactive energy provided by the combination of capacitors and reactors. Capacitor rated voltage Capacitors have been specially designed to operate in detuned bank configurations. Parameters such as the rated voltage, over-voltage and over-current capabilities have been improved, compared to standard configuration. 10
19 Rated voltage and current According to IEC standard, the rated voltage (U N ) of a capacitor is defined as the continuously admissible operating voltage. The rated current (I N ) of a capacitor is the current flowing through the capacitor when the rated voltage (U N ) is applied at its terminals, supposing a purely sinusoidal voltage and the exact value of reactive power (kvar) generated. Capacitor units shall be suitable for continuous operation at an r.m.s. current of (1.3 x I N ). In order to accept system voltage fluctuations, capacitors are designed to sustain over-voltages of limited duration. For compliance to the standard, capacitors are for example requested to sustain over-voltages equal to 1.1 times U N, 8 h per 24 h. VarPlus Can, VarPlus Box, VarPlus Box Energy and EasyCan capacitors have been designed and tested extensively to operate safely on industrial networks. The design margin allows operation on networks including voltage fluctuations and common disturbances. Capacitors can be selected with their rated voltage corresponding to the network voltage. For different levels of expected disturbances, different technologies are proposed, with larger design margin for capacitors adapted to the most stringent working conditions (VarPlus Can, VarPlus Box & VarPlus Box Energy). VarPlus Can, VarPlus Box, VarPlus Box Energy and EasyCan capacitors when used along with Detuned Reactors have to be selected with a rated voltage higher than network service voltage (U s ). In detuned filter applications, the voltage across the capacitor is higher than the network service voltage (U s ). The recommended rated voltage of capacitors to be used in detuned filter applications with respect to different network service voltage (U s ) and relative impedance is given in the table below. These values ensure a safe operation in the most stringent operating conditions. Less conservative values may be adopted, but a case by case analysis is necessary.

WARNING: the life expectancy will be reduced if capacitors are used in maximum working conditions. Since the harmonics are caused by non-linear loads, an indicator for the magnitude of harmonics is the ratio of the total power of non-linear loads to the power supply transformer rating. This ratio is denoted N LL, and is also known as G h /S n : N LL = Total power of non-linear loads (G h ) / Installed transformer rating (S n ). Example: Power supply transformer rating: S n = 630 kva Total power of non-linear loads: G h = 150 kva N LL = (150/630) x 100 = 24 % It is recommended to use Detuned Reactors with Harmonic Rated Capacitors (higher rated voltage than the network service voltage - see the Harmonic Application Tables) for N LL > 20 % and up to 50 %. Note: there is a high risk in selecting the capacitors based only on N LL as the harmonics in grid may cause current amplification and capacitors along with other devices may fail.

74 Appendix Influence of harmonics in electrical installations + Since the harmonics are caused by nonlinear loads, an indicator for the magnitude of harmonics is the ratio of the total power of nonlinear loads to the power supply transformer rating. This ratio is denoted N LL, and is also known as G h /S n : N LL = Total power of non-linear loads (G h )/ Installed transformer rating (S n ) Example: > Power supply transformer rating: S n = 630 kva > Total power of non-linear loads: G h = 150 kva > N LL = (150/630) x 100 = 24 %. Definition of harmonics The presence of harmonics in electrical systems means that current and voltage are distorted and deviate from sinusoidal waveforms. Harmonic currents are currents circulating in the networks and whose frequency is an integer multiple of the supply frequency. Harmonic currents are caused by non-linear loads connected to the distribution system. A load is said to be non-linear when the current it draws does not have the same waveform as the supply voltage. The flow of harmonic currents through system impedances in turn creates voltage harmonics, which distort the supply voltage. The most common non-linear loads generating harmonic currents use power electronics, such as variable speed drives, rectifiers, inverters, etc. Loads such as saturable reactors, welding equipment, and arc furnaces also generate harmonics. Other loads such as inductors, resistors and capacitors are linear loads and do not generate harmonics. Effects of harmonics Capacitors are particularly sensitive to harmonic currents since their impedance decreases proportionally to the order of the existing harmonics. This can result in capacitor overload, constantly shortening its operating life. In some extreme situations, resonance can occur, resulting in an amplification of harmonic currents and a very high voltage distortion. To ensure good and proper operation of the electrical installation, the harmonic level must be taken into account in selecting power factor correction equipment. A significant parameter is the cumulated power of the non-linear loads generating harmonic currents. Taking account of harmonics The percentage of non-linear loads N LL is a first indicator for the magnitude of harmonics. The proposed selection of capacitors depending on the value of N LL is given in the diagram below. N LL (%) EasyCan VarPlus (Can & Box) VarPlus Box Energy Capacitor with detuned reactor DE90182 Supply transformer Measure THDi, THDu A more detailed estimation of the magnitude of harmonics can be made with measurements. Significant indicators are current harmonic distortion THDi and voltage harmonic distortion THDu, measured at the transformer secondary, with no capacitors connected. According to the measured distortion, different technologies of capacitors shall be selected: Linear loads Non-linear loads THDi (%) EasyCan VarPlus (Can & Box) VarPlus Box Energy Capacitor with detuned reactor THDu (%) EasyCan VarPlus (Can & Box) VarPlus Box Energy Capacitor with detuned reactor The capacitor technology has to be selected according to the most restrictive measurement. Example, a measurement is giving the following results : - THDi = 15 % Harmonic solution. - THDu = 3.5 % VarPlus solution. Harmonic solution has to be selected. 66
75 Safety features DE90175 (a) (b) Self-healing is a process by which the capacitor restores itself in the event of a fault in the dielectric which can happen during high overloads, voltage transients etc. Figure 1 - (a) Metal layer - (b) Polypropylene film. When insulation breaks down, a short duration arc is formed (figure 1). DE90174 Figure 2 The intense heat generated by this arc causes the metallization in the vicinity of the arc to vaporise (figure 2). Simultaneously it re-insulates the electrodes and maintains the operation and integrity of the capacitor (figure 3). DE90173 Figure 3 DB T Pressure Sensitive Disconnector (also called tear-off fuse ): this is provided in each phase of the capacitor and enables safe disconnection and electrical isolation at the end of the life of the capacitor. Malfunction will cause rising pressure inside the can. Pressure can only lead to vertical expansion by bending lid outwards. Connecting wires break at intended spots. Capacitor is disconnected irreversibly. DB T+12+2 Cross-section view of a three-phase capacitor after Pressure Sensitive Device operated: bended lid and disconnected wires. 67
76 Appendix Protection Devices in APFC Panel Over voltage In the event of an over voltage, electrical stress on the capacitor dielectric and the current drawn by the capacitors will increase. The APFC equipment must be switched off in the event of over voltage with suitable over voltage relay / surge suppressor. Over Current Over current condition is harmful to all current carrying components. The capacitor bank components must be rated based on the maximum current capacity. A suitable over current relay with an alarm function must be used for over current protection. Short circuit protection Short circuit protection at the incomer of the capacitor bank must be provided by devices such as MCCB's and ACB's. It is recommended to use MCB or MCCB for short circuit protection at every step. Thermal Overload A thermal overload relay must be used for over load protection and must be set at 1.3 times the rated current of capacitors (as per IEC 60831). In case of de tuned capacitor banks, the over load setting is determined by the maximum over load capacity of the de tuning reactor. (1.12 = 4.2(14%), 1.19 = 3.8(7%), 1.3 = 2.7(5.7%)). If MCCB's are not present, it is recommended to use a thermal overload relay with the stage contactor to make sure the stage current does not exceed its rated capacity. Over Temperature protection The APFC controller must be tripped with the help of thermostats in cases the internal ambient temperature of the capacitor bank exceeds the temperature withstand characteristics of the capacitor bank components. Reactors are provided with thermal switches and can be isolated in the case of over temperature conditions. 68
