Abstract:

大扰动冲击后,直流逆变站的动态行为对受端电网电压稳定性将产生显著影响。研究了逆变站交流母线电压大幅波动过程中,直流逆变站各主要电气量及其与交流电网交换的动态无功的非线性轨迹;系统地分析了低压限流(voltagedependentcurrentorderlimiter,VDCOL)启动点参数、直流控制方式、电压测量时间常数等对逆变站动态无功轨迹的影响;在此基础上,识别了关键影响因素,并提出优化方案。呼盟—豫西±800kV/8000MW特高压直流受端电网大扰动时域仿真结果,表明了正确设置控制器仿真参数对客观反映电网受扰行为的重要意义,并验证了控制器参数优化改善受端电网电压稳定性的有效性。
