摘　　要：介绍了晶闸管阀运行试验过程中的暂态过电压、故障过电压及相应的保护策略。建模分析了过电压产生的机理,提出了阻容吸收和BOD触发晶闸管阀的保护策略,仿真分析结果和试验结果表明了所选保护策略的正确性和实用性。The paper describes the transient overvoltage and the fault overvoltage,and provides their protection strategies of the thyristor operational test.The mathematical model and the generation mechanism of the overvoltage are presented. The paper also puts forward the RC snubber and the protection strategies of BOD triggering thyristor.Based on the simulation and the test results, the validity and availability of protection strategies are verified.
