特高压并联电抗器感应电压试验补偿方式的计算与研究

Calculation and Research on the Compensation Method for the Ultravoltage Shunt Reactor Induced Voltage Test

为了有效提高试验系统的可靠性,避免并联电抗器感应电压试验时发电机组自励磁现象发生,采用了一种二次补偿的新型补偿方式,并对方案进行了实际验证,较于传统补偿方式,新补偿方式能在源头上避免发电机组直接带容性负载,消除发电机组自励磁的隐患。

In order to improve reliability of test system and to avoid the generator self exciting in shunt reactor induced voltage test,a new secondary compensation method is applied and validated in practice.In comarsion with traditional compensation method,the new method can avoid the direct capacitive loading of the generating unit and can eliminate the defect result by the generating unit self exciting.
