Power Line Carrier Communication Channel Modeling of Hybrid Lines in Distribution Network Based on Branch-adding Method
摘要
Abstract
A PLC channel modeling method of medium-voltage distribution network hybrid lines based on branch-adding method is proposed.According to the distribution network topology,gradually increasing each branch of the network which is utilizing branch-adding method,independent equations of VAR and current equations of KCL produced are to create a set of matrix equations which have a unique solution.Based on the matrix equations ratio relationship of unknown variables,signal transfer function is solved and the transmission characteristic of the channel is analyzed.When structure of the distribution network is changed,simply based on the original algebraic matrix equation,the increase or decrease in the correlation matrix of rows and columns is to build new algebraic matrix equations.The clear modeling method,small amount of calculation applies to topologies of tree-like network, hand in hand network and ring network. Simulation and experimental tests verify the correctness of the proposed method.关键词
