Reactive Power Compensation System for LV Distribution Network

Abstract

The decentralised reactive power compensation is used now a days in the LV distribution system by using the capacitor banks. But there are certain issues for using this capacitor banks as decentralised manner. Those issues can be overcome by using the centralised reactive power compensation method. By centralizing capacitor banks together, it can help to maintain bus voltages and power factors as well as reduce the power cable losses. Also the centralized reactive power system can be easily expanded to meet any future load increase which can not be done by using the decentralised compensation system. A reasonably sized centralized reactive power compensation system will be capable of meeting the requirements of the network with optimal solutions. So here optimization will also be done for centralised reactive power compensation system. Here the bus voltage will also be maintained and power losses will be reduced by using the centralised reactive power compensation with capacitor bank. The simulation of the centralized reactive power compensation used distribution network will be done with appropriate software.
