摘　　要：链节对冲试验是链式静止同步补偿器在投运之前必须进行的一项重要的试验,试验的目的是验证在正常和异常反复情况下及暂态故障情况下,链节耐受电压电流联合强度的能力。本文分析了链节对冲试验的原理及各阶段的工作过程;依据串联谐振理论,提出了链节对冲试验中连接电抗器的参数计算方法;根据孤岛运行的电力系统理论和前馈解耦控制理论,设计了一套完整、合理的试验方案。PSCAD|EMTDC仿真结果表明了参数设计的正确性和试验方案的合理性。Link operational test is an important test that must be done before the static synchronous compensator puts into practice. The purpose of the test is to validate the link＇s ability of withstanding the joint strength of voltage and current not only in the repeated normal and abnormal cases but transient fault cases. This paper analyzes the principle of the link operational test and the processes of the working stage; then puts forward a method on how to calculate the value of the link inductance according to the series resonance theory; and designs a set of completed and reasonable test strategy on the basis of island operation power system and feed-forward decoupling control theory. Test results of PSCAD｜EMTDC simulation provide that the parameter designing is valid and the test strategy is rational.
