Prediction Method for Carrying Capacity of Overhead Transmission Line Measuring Spatial Correlation
摘要
Abstract
Spatial correlation of wind speed was introduced into predicting carrying capacity of the overhead transmission line which firstly divided meteorological-terrain network by 600 m ×600 m and analyzed correlation between wind speed and ter-rain by means of Pearson correlation coefficient (PPC)method. Corresponding results indicate that wind speed has strong correlation with gradient,status and surface roughness of terrain. Then associated data of terrain and wind speed was brought into the improved back propagation (BP)neural network and a neural network for predicting real-time wind speed according to the terrain was obtained. The prediction error of this method is about 35% and it is able to improve precision of this method if getting more precise wind speed data. Finally,this prediction method for wind speed was combined with the prediction method for the maximum solar radiation to calculate carrying capacity of one specific line,which proved practica-bility of this method.关键词
