摘　　要：大规模交流同步电网中,某个区域发生的扰动不仅会影响到本区域,而且会通过区域间交流联络线对与之互联的其他区域电网产生影响。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。For a large synchronized interacted power grid, the disturbances inside one area may affect not only the area itself, but also other areas connected to this area through tie lines. Based on PSASP simulation models, the effect of two kinds of dis- turbances inside Siehuan power grid, that is, loss of generation and three phase to ground fault, on power oscillation of Chuan - Yu section and that of UHV tie lines connecting Huabei power grid and Huazhong power grid is studied.
