摘　　要：在实际系统运行中,采用合理的负荷电压特性模型能较准确地反映电网的潮流分布状况。基于节点负荷的取用功率是其电压的函数,提出采用两种负荷电压静态特性模型,针对不同负荷电压静态特性模型的系数对潮流计算结果的影响,对比分析各关系曲线的斜率从而确定选择负荷电压静态特性模型。所得结果可为电压敏感性负荷的潮流计算提供参考。In actual system operation, it can be more accurately reflect the distribution of power girds when using reasonable load voltage model. Because the power load at a bus is a function of its voltage, using two types of load-voltage static characteristics model is proposed. According to the influence of load-voltage static characteristic model on the power flow, comparing and analyzing the curve slope to determine the choice of load-voltage static characteristics model were carried out. The results can provide reference to the voltage-sensitive load flow calculation.
