摘要
Abstract
Aiming at the shortcomings of the traditional voltage quality evaluation methods and bottlenecks of the electric power system data analysis software, the power grid voltage quality analysis system was developed with kernel density estimation analysis method and R language. Model parameters are established from the respects of mean value, standard deviation, nuclear density estimation and violin distribution to analyze the voltage quality of power grid. The advantages (such as perfect voltage quality evaluation indicator, powerful statistical computing function and convenient data visualization) of the power grid voltage quality analysis system based on kernel density estimation and developed with R language were verified. The verification is based on the statistical analysis for the voltage data of the typical substation in Hangzhou West Lake area in 2016.关键词
