摘　　要：外网等值是电力系统研究的重要分支之一,通过静态等值和动态等值等手段,描述外部电网特性,以便能够完整的描述所研究的电网特性。潮流计算是研究电力系统的重要手段之一,利用电网模型和参数、拓扑连接关系和电网运行方式数据,求解母线电压幅值和相角,并计算电网各支路的功率,获取电网信息。文章对青海电网D5000系统现有的外网等值模型通过典型案例验证了等值模型的合理性,并分析了对潮流计算的影响。The external network equivalence is an important branch of the power system research. The characteristics description of the external network to the power grid to be researched is necessary to describe perfectly the characteristics of the power grid to research. By typical cases this paper validates the rationality of the equivalence model of the external network to the Qinghai power grid in the D5000 system and the effect of the equivalence model to the power flow calculation of the Qinghai power grid is also analyzed.
