四川电网扰动对川渝断面及特高压联络线功率波动影响伤真研究

Simulation Study on Effect of Disturbances inside Sichuan Power Grid on Power Oscillation of Chuan-Yu Section and UHV Tie Lines

摘要:

基于四川电网及华北、华中电网PSASP仿真模型，研究了四川电网不同地点切机及三相接地短路两种扰动类型对川渝断面及华北、华中电网特高压联络线有功功率波动的影响。

Abstract:

Based on the PSASP simulation models of the Sichuan power grid and the North China power grid and the Central China power grid，the paper studies the impact of load reduction and three - phase fault disturbances in different locations of the Sichuan power grid on active power oscillation in the Sichuan - Chongqing section and the UHV AC tie - line between North China and Central China．
