摘要
为了2013年南方电网北郊、木棉、水乡STATCOM一期工程投产需要,进行了STATCOM对系统影响的专题研究。基于RTDS实时仿真软件建立了南方电网STATCOM试验研究系统模型,采用大扰动下暂态稳定时域仿真分析了多套STATCOM对故障时暂态期间电压恢复以及(特)高压直流功率恢复的影响。研究表明,多套STATCOM的投入对直流系统逆变站换流母线电压、严重故障下直流长期换相失败的持续时间以及直流功率恢复有明显改善,且母线接地短路开关拒动等严重故障下的改善效果更加明显,而对故障瞬间发生的换相失败改善效果不明显。
In need of preparing Beijiao, Mumian and Shuixiang STATCOM first-stage projects in China Southern Power Grid in 2013 for operation, we studied the effect of STATCOM on power system, and established a model of the STATCOM in the RTDS real-time simulation system to analyze the influences of multi-STATCOM on voltage recovery and （U） HVDC power fault recovery. The results show that the system operating with multi-STATCOM greatly improves in the bus voltage recovery of inverter stations, decreasing the commutation failure duration under serious failure, and improves the DC power recovery. The improvement is obvious for some fault conditions such as circuit breaker rejection fault, but quite limited for commutation failure conditions at the fault moments.
