Electrical Network Management System
Optimisation of the electrical network Measure to understand Understand to control Control to optimise Cost of power and fluids Power quality Power availability 2
Improvement process Collect measurement data Organise measurement data Devices Communication Software Check Implement Solutions Design / Solutions Analysis Improve the distribution system 3
Optimisation of the electrical network : costs Monitor load curves Reduce energy cost Monitor load curve -> implement load-shedding schemes -> concentrate heavy consumptio during off-peak times -> avoid exceeding stipulated limits Monitor power factor -> implement reactive compensation schemes Optimize utility contract & avoid penalties 4
Optimisation of the electrical network : costs Reduce energy cost Sub-metering / cost allocation -> allocate internal cost -> implement awareness program (best practices, peak shaving) Multi-sites aggregation to negotiate better rates Allocate energy costs 5
Optimisation of the electrical network : costs Optimize investment Identify spare capacity through analyze of Energy usage Optimize safety margin between installed Power and demand Power -> avoid unnecessary investme when modifications or extensions are required Extend equipment life time & reduce losses through Power quality improvement (cables, transformers, capacitors, moto electronics...) Analyse energy usage 6
Optimisation of the electrical network : quality Monitor Power Factor / Reactive Energy Harmonics Neutral Current due to addition of H3, 6, 9... & Current unbalance Voltage or Current unbalance Frequency on Diesel Generator Voltage sags & swells due to load fluctuation (motor starting ), power up of transformer or capacitor banks, lightning... Transients Monitor THD 7
Optimisation of the electrical network : quality To avoid Increased losses in cables & transformers Equipment destruction or reduced life time due to overheating (transformers, capacitors, motors VSD s, neutral cables ) & vibrations (motors) Untimely CB tripping Process disturbance (sensitive equipment: relays, VSD PLC s, motor speed instability...) Perturbation of communications Monitor currents & voltages & to check energy supply complianc 8
Optimisation of the electrical network : availability Help for preventative maintenance -> detect problem early -> avoid shut down -> minimize production losses Alarm on key parameters & record events Alarming on key parameters Number of CB O/C operations CB contact wear Identify polluting loads (high level of Harmonics) & pull them apart from sensitive loads, install filters or even chang them Balance bus-bars after demand Power analysis 9
Optimisation of the electrical network : availability Help for corrective maintenance -> minimize down time -> minimize production losses Look at Sequence of Events Recording, Waveform captures Identify origin of problems : - internal cause - or problem coming from Utility Check Voltage disturbances, overloads...
