Abstract

The invention discloses a method for predicting a line loss rate of a power distribution network. The method comprises the steps of determining multiple electrical characteristic parameters, influencing the line loss rate, of the power distribution network, performing standardization processing on parameter values of the electrical characteristic parameters, and performing normalization processingon the line loss rate; by taking the parameter values of the electrical characteristic parameters as inputs of an input layer, and taking the value of the line loss rate as an output of an output layer, building an initial neural network model, wherein the initial neural network model comprises at least one hidden layer; determining the number of hidden layer nodes; by dynamically adjusting an inertial factor and a learning factor of a particle swarm algorithm, improving the particle swarm algorithm; by utilizing the improved particle swarm algorithm, optimizing a weight value and a thresholdvalue of the initial neural network model to determine an optimized neural network model; and inputting the electrical characteristic parameters of a power distribution network line to the optimizedneural network model, and predicting the line loss rate corresponding to the electrical characteristic parameters by utilizing the optimized neural network model.

Description

technical field [0001] The invention relates to the technical field of distribution network lines, and more specifically, to a method and system for predicting the line loss rate of a distribution network. Background technique [0002] With the development of the national economy and social productivity, my country's demand for energy has also greatly increased. Electric energy has become the most widely used secondary energy in my country's national economy and people's life by virtue of its high efficiency of transmission and conversion, convenient control, use, and cleanliness. With the increase of power demand, my country's power distribution network becomes increasingly large and complex. However, due to the serious loss of lines, the outdated management of medium and low voltage distribution network equipment in underdeveloped areas, the serious loss of medium and low voltage distribution network, and low power utilization efficiency. [0003] The 10kV medium-voltage...
