Abstract

The invention provides a rail transit system traction energy consumption optimization boundary detection method based on an operation plan. The method comprises the steps of constructing a basic database of a target rail transit line; calculating reference operation schemes and corresponding traction energy consumption of all planned operation trains of the target rail transit line by adopting a basic traction calculation scheme; adopting an optimized traction calculation scheme to calculate optimized operation schemes and traction energy consumption of all planned operation trains of the target rail transit line under the energy-saving optimization target; and according to the traction energy consumption of the reference operation scheme and the optimized operation scheme, calculating theenergy saving amount and the energy saving ratio of the optimized operation scheme relative to the reference operation scheme, constructing a train traction energy consumption limit database, and determining the traction energy consumption optimization limit. According to the method, the traction energy consumption energy-saving optimization limit of the given rail transit operation plan can be accurately estimated, so that a reference basis is provided for improving the energy-saving level of the rail transit system in the operation plan compiling and adjusting level.

Description

technical field [0001] The invention relates to the technical field of comprehensive energy-saving optimization of a rail transit system, in particular to a method for detecting the optimal limit of traction energy consumption of a rail transit system based on an operation plan. Background technique [0002] As an important part of the comprehensive transportation system, the rail transit system has received extensive attention and rapid development in recent years. In the process of construction, operation and development of the rail transit system, optimization and improvement simply starting from part of the entire life cycle of the rail transit system can no longer meet the specific needs of the current rail transit system towards modernization, intelligence and network development. . The rail transit system is a complex system involving many factors, objects, and time and space. How to use effective means to accurately evaluate the energy consumption level of the rail ...
