20 Section 2 REF611 overview 1MRS A The LHMI of the IED contains several elements. Display Buttons LED indicators Communication port Display The LHMI is used for setting, monitoring and controlling. The LHMI includes a graphical display that supports two character sizes. The character size depends on the selected language. The amount of characters and rows fitting the view depends on the character size. Table 4: Characters and rows on the view Character size Rows in view Characters on row Small, mono-spaced (6x12 pixels) 5 rows 20 Large, variable width (13x14 pixels) 4 rows min 8 The display view is divided into four basic areas GUID-24ADB A-4563-AACE-1FAA193A8EF9 V1 EN Figure 3: Display layout 1 Header 2 Icon 3 Content 4 Scroll bar (displayed when needed) 14 REF611

21 1MRS A Section 2 REF611 overview LEDs Keypad The LHMI includes three protection indicators above the display: Ready, Start and Trip. There are also 8 programmable LEDs on front of the LHMI. The LEDs can be configured with the LHMI, WHMI or PCM600. The LHMI keypad contains push-buttons which are used to navigate in different views or menus. With the push-buttons you can give open or close commands to one object in the primary circuit, for example, a circuit breaker, a contactor or a disconnector. The push-buttons are also used to acknowledge alarms, reset indications, provide help and switch between local and remote control mode. GUID-B681763E-EC AC57-1FD F7 V1 EN Figure 4: LHMI keypad with object control, navigation and command pushbuttons and RJ-45 communication port 2.5 Web HMI The WHMI enables the user to access the IED via a web browser. The supported web browser version is Internet Explorer 7.0 or 8.0. WHMI is disabled by default. WHMI offers several functions.

Operational information and controls are available through these protocols. Some communication functionality, for example, horizontal communication between the IEDs, is only enabled by the IEC communication protocol. The IEC communication implementation supports monitoring and control functionality. Additionally, parameter settings and disturbance and fault records can be accessed using the IEC protocol. Disturbance records are available to any Ethernet-based application in the standard COMTRADE file format. The IED can send and receive binary signals from other IEDs (so called horizontal communication) using the IEC GOOSE profile, where the highest performance class with a total transmission time of 3 ms is supported. The IED meets the GOOSE performance requirements for tripping applications in distribution substations, as defined by the IEC standard. The IED can simultaneously report events to five different clients on the station bus. The IED can support five simultaneous clients. If PCM600 reserves one client connection, only four client connections are left, for example, for IEC and Modbus. REF611 17

If more than 30 IEDs are to be connected, it is recommended that the network is split into several rings with no more than 30 IEDs per ring. 18 REF611

25 1MRS A Section 3 Section Standard configurations REF611 is available in two alternative standard configurations. To increase the user friendliness of the IED s standard configurations and to emphasize the IED's simplicity of usage, only the application-specific parameters need setting within the IED's intended area of application. The standard signal configuration can be altered by LHMI, WHMI or the optional application functionality of the Protection and Control IED Manager PCM600.

27 1MRS A Section 3 Programming is easily implemented with three switch group functions including input switch group (ISWGAPC), output switch group (OSWGAPC) and selector switch group (SELGAPC). Each switch group has several instances. Connections of binary inputs to functions, GOOSE signals to functions, functions to functions, functions to binary outputs and functions to LEDs have been preconnected through corresponding switch groups. Change the parameter values of the switch groups to modify the real connection logic and the application configuration Input switch group ISWGAPC The input switch group ISWGAPC has one input and a number of outputs. Every input and output has a read-only description. ISWGAPC is used for connecting the input signal to one or several outputs of the switch group. Each output can be set to be connected or not connected with the input separately via the OUT_x connection setting. GUID-2D549B56-6CF7-4DCB-ACDE-E9EF601868A8 V1 EN Figure 7: Input switch group ISWGAPC Output switch group OSWGAPC The output switch group OSWGAPC has a number of inputs and one output. Every input and output has a read-only description. OSWGAPC is used for connecting one or several inputs to the output of the switch group via OR logic. Each input can be set to be connected or not connected with the OR logic via the IN_x connection settings. The output of OR logic is routed to switch group output. REF611 21

Every input and output has a read-only description. Each output can be set to be connected with one the of inputs via the OUT_x connection setting. An output can also be set to be not connected with any of the inputs. In SELGAPC, one output signal can only be connected to one input signal but the same input signal can be routed to several output signals.

31 1MRS A Section 3 perspective. Diagrams show the default functionality with simple symbol logics forming principle diagrams. The functional diagrams are divided into sections with each section constituting one functional entity. Protection function blocks are part of the functional diagram. They are identified based on their IEC name but the IEC based symbol and the ANSI function number are also included. Some function blocks, such as PHHPTOC, are used several times in the configuration. To separate the blocks from each other, the IEC name, IEC symbol and ANSI function number are appended with a running number, that is an instance number, from one upwards. If the block has no suffix after the IEC or ANSI symbol, the function block has been used, that is, instantiated, only once. Switch groups Switch group information can be divided into three levels. The first level is a configuration overview. All switch groups in the configuration are presented in an overview figure. The figure provides general information about the relationship between different switch groups. The second level presents function group information. It explains how the switch groups belong to a special function as well as related function blocks. The third level presents detailed information about the switch groups. It provides information about a specific switch group including the logic connection of the input and output, default connection and port description. Conventions used in switch group figures: The text in the symbol indicates the logic connections of the function's inputs or outputs. The text is a combination of a function block name and the input or output name. They are connected with a _ symbol. If there are many lines of text in an output symbol, each line indicates a signal. The switch group output is routed to all these signals. If there are many lines of text in an input symbol, each line indicates a signal. All signals are routed to a switch group input via an OR logic. The text above the connection line is the description of the port. If there is no text in the connection line, the port description is the same as the text in the symbol. A dashed arrow within the switch group function box indicate the default connection of the switch group. REF611 25

32 Section 3 1MRS A 3.5 Standard configuration A Applications Functions The standard configuration for non-directional overcurrent and directional earthfault protection is mainly intended for cable and overhead-line feeder applications in isolated and resonant-earthed distribution networks. The IED with a standard configuration is delivered from the factory with default settings and parameters. The end-user flexibility for incoming, outgoing and internal signal designation within the IED enables this configuration to be further adapted to different primary circuit layouts and the related functionality needs by modifying the internal functionality using PCM600.

In addition, there is a dedicated protection stage (INTRPTEF) either for transient-based earth-fault protection or for cable intermittent earth-fault protection in compensated networks. A dedicated non-directional earth-fault protection block (EFHPTOC) is intended for protection against double earth-fault situations in isolated or compensated networks.

LED 4 is used for the thermal overload protection alarm indication. The circuit-breaker failure protection (CCBRBRF1) is initiated via the start input by a number of different protection stages in the IED. The circuit-breaker failure protection function offers different operating modes associated with the circuit breaker position and the measured phase and residual currents. The breaker failure protection has two operating outputs: TRRET and TRBU. The TRRET operate output is used for retripping its own breaker through the Master Trip 2. The TRBU output is used to give a backup trip to the circuit breaker feeding upstream. For this purpose, the TRBU operate output signal is connected to the output PO2 (X100: 8-9). LED 8 is used for backup (TRBU) operate indication. REF611 33

The autoreclose function is configured to be initiated by operate signals from a number of protection stages through the INT_1...6 inputs and by start signals through the DEL_INT_2 4. It is possible to create individual autoreclose sequences for each input. The autoreclose function can be blocked with the INHIBIT_RECL input. By default, the operations of selected protection functions are connected to this input. A control command to the circuit breaker, either local or remote, also blocks the autoreclose function via the CBXCBR_SELECTED signal. The circuit breaker availability for the autoreclose sequence is expressed with the CB_READY input in DARREC1. In the configuration, this signal is connected with an always true signal through the SELGAPC1. As a result, the function assumes that the circuit breaker is available all the time. The autoreclose sequence in progress indication INPRO is connected to the alarm LED REF611
