Abstract
Aiming at the insufficiency of traditional methods for voltage quality analysis,and based on probability statistics,this paper proposes a novel method for analyzing main power network.The proposed method does analysis with the mathematical expectation,standard deviation and probability distribution curve of voltage.The average values,standard deviations and probability distribution curves of voltage in seven typical power plants/substations such as Dali Substation,Yanshan Substation,Pannan Power Plant etc.in January and August,2009 are calculated with the propposed method.In comparison of the results between the proposed and currently methods,it proves that for the overall voltage level,the average value is a better index than the highest and lowest values;for the voltage fluctuation level,the voltage standard deviation is better than the difference between the highest and lowest values;for the voltage quality,the probability distribution curve is better than the pass percent of voltage.关键词
