摘　　要：为验证可控避雷器在混合直流输电系统中抑制过电压的基本控制策略和保护水平,搭建了基于可控避雷器的混合直流输电动模试验系统,并建立了相应的PSCAD仿真模型。通过模拟受端系统网侧电压跌落故障,在仿真研究和动模试验中对可控避雷器的控制策略和过电压保护水平进行验证,结果表明两者具有较高一致性。In order to verify the basic control strategy and protection level of the controllable arrester in hybird DC transmission system to suppress the overvoltage,the hybird DC transmission dynamic model experiments system based on the controllable arrester and corresponding PSCAD simulation model is established.By simulating the voltage drop fault on the grid of receiver system,the control strategy and overvoltage protection level of the controllablearrester are viertied in the simulaiton and dynamic model experiments system,and the results show that the two have high consistency.
