| 摘 要： | 介绍了我国第1套适用于灵活交流输电系统(FACTS)和高压直流输电系统(HVDC)的高压晶闸管阀过电流试验装置的基本原理。针对试验过程中可能产生的瞬时过电压和故障过电压分别建立了数学和仿真模型,分析了过电压的产生机理、危害及特点。在上述分析的基础上对不同的保护策略进行比较,提出阻容吸收回路与BOD(break over diode)触发晶闸管阀相结合的新型过电压保护策略,理论分析和仿真结果都证明所提出的保护策略的正确性和有效性,从而确保过电流试验装置的安全可靠运行。

| Abstract: | The principle of the first overcurrent test equipment for FACTS and HVDC thyristor valve in China is introduced. The mathematics and simulation model for transient and fault overvoltage are established and their generation mechanisms, harm and characteristic are analyzed. Based on the study above, some protective methods are compared, and a novel protection strategy is proposed, which is composed of BOD(break over diode) triggering thyristor valve and RC snubber circuit. Its validity is verified by the theoretical analysis and simulation results. So the safe operation of the overcurrent test equipment is guaranteed. |
