Electricity utilization energy consumption index assessment method facing rail traffic

Abstract

The present invention relates to the rail traffic electronic utilization energy consumption analysis field, especially to an electricity utilization energy consumption index assessment method facing rail traffic. The method comprises concretely steps: (1) performing graduation of energy consumption indexes, and generating projection indexes in a grade range according to the random distribution principle; (2) establishing a projection target function (3) through taking the projection indexes as a projection value as a certain direction to solve the maximum value of the projection target function through the genetic algorithm, and solving a projection direction and an optimal projection value; and (4) establishing an energy consumption assessment model according the projection value and the assessment grade scatter diagram. The electricity utilization energy consumption index assessment method facing the rail traffic employs the genetic algorithm and the projection pursuit method to provide an electricity utilization energy consumption index assessment method facing the rail traffic to establish an energy consumption index comprehensive assessment genetic projection pursuit model, employs examples to prove the model feasibility, and performs comprehensive assessment of a transfer station and an operation line, and the assessment result is comprehensive, objective and reasonable so as to provide important basis for assessment of the rail traffic electric energy consumption.

Description

technical field [0001] The invention relates to the field of power consumption analysis of rail transit, in particular to a rail transit-oriented power consumption index evaluation method. Background technique [0002] Urban rail transit has the characteristics of large transport capacity, fast and comfortable, safe, punctual, environmental protection, energy saving, and less land occupation. It has become the main means of solving road traffic congestion problems in large and medium-sized cities. With the rapid development of my country's social economy and the increasing urbanization process, the scale of my country's urban rail transit construction continues to expand, and the impact of urban rail transit on the power quality and transient process of urban power grids has become increasingly apparent. [0003] The urban rail transit power supply system is responsible for providing traction power for electric trains and providing power and lighting power for various operat...
