摘要
随着广东电网多馈入以及交、直流混合复杂网络格局的形成,外送输电容量的比例逐渐增加,对广东电网电压稳定问题产生了重要的影响。根据2009年电网实际情况,分析了广东电网电压稳定故障失稳模式,提出了针对机组、负荷和线路采用不同的模式分析策略,通过对失稳故障筛选和动态仿真后,提出了抑制失稳的措施,以及不同措施在故障中的组合和优化,具有较强的工程实际意义。
With the forming of complex Guangdong AC/DC power system, the proportion of input capacity increases gradually. It exerts great influence on the voltage stability of Guangdong Grid. According to the real situation of Guangdong Grid in 2009, the instable model of voltage stable fault in Guangdong Grid is analyzed, various model analysis methods are applied in generators, load and transmission lines. Through the screening and dynamic simulation of the instable fault, measures to restrict instability are presented, the composition and optimization of these measures in faults are introduced. It is really meaningful to practical programs.
