Control system for measuring energy consumption of urban rail transit and evaluation method

Abstract

The invention discloses a control system for measuring the energy consumption of urban rail transit and an evaluation method. The control system comprises a vehicle-mounted energy consumption control unit, a data management unit and a ground energy consumption control unit. The control system has the beneficial effects that the system is a multi-path sampling energyconsumption metering system; drive control is carried out by adopting a permanent-magnet synchronous DC motor; a double-energy control module is built by using a super capacitor and a lithium battery for vehicle-mounted energy conversion control; train force analysis and modeling are not needed; a large quantity of nonlinear analysis or intelligent optimization calculation is not needed; traction energy consumption, regenerative braking energy and auxiliary energy consumption can be measured and monitored by directly utilizing collected voltage and current data; the control system has the functions of real-time storage and display of energy consumption data; the energy consumption data can be uploaded to the ground energy consumption control unit through the data management unit; the labor cost is reduced; the control system has a fault detection function; and the fault can be accurately reported when the system fails.

Description

technical field [0001] The invention relates to an urban rail transit control system and an evaluation method, in particular to an urban rail transit energy consumption measurement control system and an evaluation method, belonging to the technical field of urban rail transit applications. Background technique [0002] Urban rail transit is an important urban infrastructure and a major livelihood project. It is of great significance for improving urban public transportation service capabilities, guiding and optimizing urban spatial layout, achieving sustainable urban development, stable growth, and benefiting people's livelihood. In recent years, the streamlining of administration and decentralization of urban rail transit has gradually entered the "fast lane". [0003] The operation of urban rail transit mainly depends on the consumption of electric energy, and the consumption of electric energy is quite huge. According to statistics from the China Urban Rail Transit Assoc...

Problems solved by technology

In the power system, there are also energy-saving methods that use resistance braking, regenerative braking, and energy storage devices, but they all use a single energy consumption control, which cannot realize the interconnection of ground energy consumption and vehicle energy consumption, and cannot effectively store energy and energy consumption. conversion, which largely wastes energy

At the same time, traditional energy statistics and management methods cannot evaluate and evaluate energy consumption, realize energy optimization, reduce energy consumption, and realize green transportation and green cities
