基于PSASP的西藏林芝电网电压稳定研究

Study on Voltage Stabilization of Tibet Nyingchi Power Grid Based on PSASP

西藏林芝地区随着经济水平的日益增长,电网也迅速发展,规模逐步扩大,结构日益复杂,实现了区域整体连接。林芝电网的负荷又多以商业和民用电力负荷为主。为此,应用电力系统分析综合程序(PSASP)中的小干扰电压稳定性新判据方法,对西藏林芝电网进行详细的电压稳定计算与分析,得出电网中薄弱母线、薄弱区域及电压稳定裕度等稳定评估数据。研究结果为林芝电网的运行、调度和系统的电压稳定性监控提供理论依据。

With the economic growth of Nyingchi, Tibet, the electric power grid has been quickly developing. As the result, the regional integral connection of has been achieved, its scales and the structure becomes bigger and more complex than before, in which the commerce and the civil power loads are main kind of power loads. In order to get the operation of Nyingchi power grid more security and stability. The new criterion method of small disturbance voltage stability in power system analysis software package （PSASP） is applied to calculate and analyze the voltage stabilization detailedly for Nyingchi power grid to recognize the weak buses and areas. Therefore, the voltage stability margin is carried out. Finally, some significant suggestions are offered for the system operation and dispatching, as well as the monitoring and control of the voltage stability.
