摘　　要：对电网大扰动进行实测试验,运用所得数据拟合出配电网络的综合负荷模型,并据此计算电网稳定性,对电网的暂态稳定性及其电压稳定性展开定量分析。仿真计算结果显示,利用该综合负荷模型所得电网的动态特性明显更符合实情,能够全面反映整个配电网的动态特性。The comprehensive load model of the distribution network was fitted by the measured data of the large disturbance of the power grid.Based on this,the stability of power grid was calculated,and the transient stability and voltage stability of power grid were analyzed quantitatively.The simulation results showed that the dynamic characteristics of the power grid obtained by using the integrated load model were obviously more in line with the actual situation,and could fully reflect the dynamic characteristics of the whole distribution network.
