| 摘要: |
| 四川电网二滩水电站和500kV输变电系统投入运行后，电网实际运行中出现若干问题。针对丰水期负荷中心因缺少无功补偿和火电机组电压支撑而出现的电压薄弱问题，运用电力科学院的电力系统分析综合程序PSASP(Power System Analysis Synthesis Program)对电网的不同运行方式进行稳态潮流分析、静态电压稳定分析以及暂态稳定分析，研究四川电网在发生典型扰动时电网电压稳定水平，找出电压薄弱区域。 |

| Abstract: |
| Several problems have occurred in Sichuan power system after Ertan Hydroplant and500kV-transmission systems are put into operation.The main problem of voltage weakness during high-water period is caused by the short of reactive power compensation and dynamotors'voltage support in load centers.PSASP(Power System Analysis Synthesis Program)is used in stable power flow analysis,static voltage stability analysis and transient stability analysis under different operating modes.The voltage stabilization level of Sichuan power system with typical disturbances is studied to find out the areas of voltage weakness. |
