华北电网综合负荷建模研究

Study on Synthesis Load Modeling for North China Power Grid

针对华北全网220kV变电站进行了负荷特性普查和分类,选取不同类型的典型变电站进行了详细的负荷调查,采用统计综合法建立了考虑配电网络的各典型变电站的综合负荷模型(synthesis load model,SLM),将建模结果推广应用到华北全网,并对采用统计综合法建立的SLM对华北电网安全稳定水平的影响进行了仿真分析。

Based on the results of general investigation of 220 kV substations in North China power grid, the load characteristics are classified, and detailed load characteristic investigation of selected different kinds of typical substations are carried out. By use of statistical synthesis, the synthesis load models （SLM） for typical substations, in which the distribution networks are taken into account, are built; and the modelling results are disseminated and applied to whole North China power grid. Besides, using the built SLM, the influences of the built SLM on security and stability of whole North China power grid are simulated.
