摘要
电力系统运行状态的识别对于电力系统的安全运行具有重要意义,在已有的关于电力系统运行状态划分的基础上,提出判断电力系统运行状态关键性的实用量化指标,采用基于信息熵的算法,对实例集进行分析和学习,构建决策树用以对电力系统运行状态进行状态识别和判断。
The identification of the operating condition of power system has a great significance to the safe operation of the grid. Based on the existing division of operating conditions of power system, the key quantitative indicators are proposed prac- tically for determining the operating condition of power system. Using information entropy algorithm, the example set is analyzed and learned, and the decision tree are established, which is used to identify and estimate the operating condition of the power system.
