Abstract

The invention provides a method for detecting the optimal limit of traction energy consumption of a rail transit system based on an operation plan. And the corresponding traction energy consumption; use the optimal traction calculation scheme to calculate the optimal operation scheme and traction energy consumption of all planned trains on the target rail transit line under the energy-saving optimization goal; according to the traction energy consumption of the reference operation scheme and the optimal operation scheme, calculate the optimized Based on the energy saving and energy saving ratio of the operation plan compared with the reference operation plan, a database of train traction energy consumption limit is constructed to determine the optimal limit of traction energy consumption. This method can accurately estimate the energy-saving optimization limit of traction energy consumption for a given rail transit operation plan, and then provide a reference for improving the energy-saving level of the rail transit system at the level of operation plan preparation and adjustment.

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 ...
