摘　　要：结合华北电网安全稳定计算分析工作研究了负荷模型的变化对系统稳定计算结果的影响,探讨了新的负荷模型在局部地区电网的适应性等问题,研究了负荷模型和参数变化对系统稳定水平影响的机理,对华北电网负荷模型和参数的选取提出了建议。Combining with security and stability analysis of North China Power Grid, the impact of changes of load models on calculation results of system stability is researched. The problems, such as the adaptability of new load model to local regional power network and so on, are analyzed. Based on the typical operating schemes of North China Power Grid in 2005, the mechanism that how the variation of load models and parameters impacts system stability level is researched as well, and the reasonable explanation for the phenomenon that in local regional power network where new induction motor model is used and the voltage after faults is difficult to restore is given. Finally, some suggestions on load model and parameter selection for North China Grid are proposed.
