电力系统供电保证率计算

The Guaranteed Efficiency Calculation of the Power System

将电力系统中电源出力、负荷及网损作为互为独立的随机变量，应用随机变量函数的概率分布规律构造了计算电力系统供电保证率的数学模型和方法，结合一个５节点系统进行了分析计算。

This paper regards power output load and power losses of the power system as three independent stochastic variations.The probability theory of the stochastic varation function is used to develop the mathmatical model and method for calculating the guaranteed efficiency of the power system. The a 5 nods system was calculated as an example.
