摘　　要：这里通过理论分析和仿真计算,研究了链式静止同步无功补偿器(STATCOM)接入系统的短路容量与运行状态的关系,提出了链式STATCOM能够正常运行的系统条件:系统短路容量必须大于某限值,即接入点最小容量。通过建立链式STATCOM等效电路,推导出链式STATCOM在正常运行状态下所要求的系统最小短路容量计算公式,并通过在PSCAD/EMTDC软件中的仿真算例,验证了系统短路容量对链式STATCOM运行状态影响的分析。The relationship of the operation condition of the cascaded static synchronous compensator（STATCOM） and the system short circuit capacity is studied by theoretical analysis and simulation.The cascaded STATCOM operation condition is presented that the system short circuit capacity must excess a minimum value, which is the minimum sys- tem short circuit capacity.By modeling the equivalent circuit of the cascaded STATCOM, the minimum value of the system short circuit capacity can be calculated.The analysis is verified by simulation results in PSCAD/EMTDC.
