本文介绍了一套二-三柱自饱和型静止无功补偿装置及其在解决轧机无功冲击问题中的应用。
This paper describes a set of twin-tripler self-saturated Reactor static var compensator (nominal capacity is 4050kVA) and its application in solving the problems of rolling mill loads.
该补偿装置是并联型静止无功补偿装置，由主电路、检测电路、控制电路、驱动电路四部分组成。
The compensation device is shunt static var compensator which includes 4 main parts: main circuit, measuring circuit, control circuit and drive circuit.
传统的TCR 型静止无功补偿装置都是在高压侧直接补偿无功，对串联晶闸管的特性以及绝缘、保护和测量都有较高的要求，装置的成本较高。
Traditional TCRs compensate reactive power from high voltage side of transformer, so it demands highly of thyristor and its protection and measurement, thus the cost ofequipment is higher.
