Study on 10 kV Dynamic Var Compensator for Substation

研究了将FC+TCR型的电容-电感型动态无功补偿装置用于10 kV的动态无功补偿。介绍了SVC及电容-电感型动态无功补偿装置的基本原理、补偿容量的确定方法及控制与保护系统。在电力系统冲击型负荷较大的趋势下,该SVC利用晶闸管可控硅的开关原理,瞬时地改变无功功率,用以补偿或吸收负载所需的无功,可改善对10kV母线电压的冲击影响状况。

This study adopted FC+TCR(FC+thyristor controlled reactor) capacitor-inductor dynamic reactive power compensating device in 10 kV dynamic reactive power compensation.The principle,the way to confirm the compensating capacity and the control and protecting system of static var compensator(SVC) and capacitor-inductor dynamic reactive power compensating device were introduced.At the trend of bigger impulse load in power supply system,making use of the thyristor s switching principle,this SVC can change the rea...
