| 摘 要： | 在电力系统中装设静止无功补偿装置(SVC)是控制无功功率、保证电压质量的有效手段,他根据无功功率的需求,对无功器件(电容器和电抗器)进行投切或调节。晶闸管投切电容器(TSC)是静止无功补偿技术的发展方向,这种装置的关键问题是如何对作为电容器投切开关的晶闸管进行控制。针对TSC低压无功补偿装置的结构,对晶闸管的触发电路进行详细的设计和分析,仿真结果证明了设计的正确性。

| Abstract: | In power system,Static Var Compensation(SVC) technology can switch or control the reactive device(capacitor and reactor) which is an effective method for controlling reactive power and insuring voltage stability.Thyristor Switching Capacitor(TSC) is the developing direction in the field of Static Var Compensation technology.The key problem of the device is how to control the thyristor which is as the switch of the capacitor.Based on a kind of TSC device,the triggering circuit for the thyristor is designed and analysed in detail.The result of simulation proves the design is right. |
