摘　　要：为了评估贵广Ⅱ回直流输电系统SSDC激活事件的正确性及系统的SSO风险,利用PSCAD/EMTDC软件对兴仁换流站故障录波数据进行分析,通过对SSDC子系统进行录波数据的回放仿真,复现出与实际事件记录基本吻合的SSDC激活事件。结果表明:这些激活事件是SSDC正常动作的结果;但在这些SSDC激活事件过程中所激发的SSO分量幅值不大,并且衰减很快,因此不存在危及系统安全运行的SSO风险。In order to evaluate the correctness of the SSDC active events occurred in Guizhou - Guangdong II HVDC system and the SSO risk of the system, this paper analyzes the fault recording data in Xingren Convertor Station through playback simulation of the SSDC active events with PSCAD/EMTDC software, reappearing the active events that are basically in agreement with the practical ones, and showing that the practical active events are the responses to the normal actions of SSDC device. However, the amplitude of SSO component is relatively small and decays quickly in these events, so there is no SSO risk enough to endanger the safe operation of the Guizhou - Guangdong Ⅱ HVDC system.
