摘要
对常规Ｗａｒｄ等值的非线性误差进行了分类和分析，并对扩展Ｗａｒｄ法进行了改进，使之能较准确地体现外网重要并联无功补偿元件对内网的作用，给出了数值试验结果。改进后的扩展Ｗａｒｄ法已在河南电网ＥＭＳ中得到实际应用。
The classification and analysis of nonlinear error of classical Ward equivalent are done An improved extended Ward method, where the effect of some important external shunt reactive compensators on internal network can be considered accurately, is proposed Some results of numerical tests are presented The practical application of the improved extended Ward method to the EMS in He'nan power system control center in China is reported
