Abstract :
This paper presents the simulation and investigation of switching large shunt capacitor bank in a 230kV Thailand substation system. Simulation is performed using PSCAD/EMTDC. The inrush current is generated by energizing of the 4×72 Mvar, 230 kV shunt capacitor banks. The purpose is to observe the inrush current to ensure safe and successful operations of the shunt capacitor banks. In addition, the effects of parameters such as sizing of current limiting reactor (CLR), pre-insert resistor (PIR) and 6% detuning reactor are investigated. The results of simulations are shown that the 6% detuning reactor can reduce inrush current more than other methods.
