Thermal Sensor Configuration Method for Dynamic Rating of Overhead Distribution Lines Based on Gappy Principal Component Analysis-Genetic Algorithm
摘要
Abstract
The dynamic rating technology for overhead distribution lines can enhance the transmission capacity of the lines on the premise of ensuring safety,and is an economically efficient method to handle short-term peak power transmission.The conductor temperature is one of the core indicators for dynamic rating of overhead lines.Generally,a large number of thermal sensors need to be installed on the lines for collection,but the investment is substantial and difficult to implement.In this paper,an optimization method for dynamic thermal sensing of overhead distribution lines based on the gappy principal component analysis(GPCA)-genetic algorithm(GA)is proposed.It selects the rational positions for thermal sensors on overhead distribution lines,precisely calculates the temperature distribution across the entire line,and reduces the number and investment of thermal sensor installations.Firstly,a current-carrying capacity calculation model considering the insulation medium of overhead distribution lines and a combined reconstruction model of GPCA are established to precisely reconstruct the thermal characteristics of the entire line.Secondly,GPCA-GA is employed to determine the optimal number of sensors and deployment positions,improving the thermal reconstruction accuracy of the distribution lines.Finally,the effectiveness of the proposed method is verified by taking 10 kV overhead distribution lines in a certain area as a case.关键词
