摘要
本文提出了应用功能分解法．并采用Ｐ、Ｑ作为状态变量的状态估计的理论和方法．以减少求解方程的维数，和不必处理三角函数的非线性方程的求解过程，因而较传统方法有高的实时性。还分析了在提高ＡＧＣ经济价值和效益统计中的应用．
A new method of state estimate by function decomposition by mean of the P. Q as the state variabiles in power systems is presented.The method is possessed of a good realtime function because of avoidins the solution to all network and calculation of triangle function. the application to the economic effect of .AGC is analysised.
