Abstract

The invention discloses a rail transit traction system test method and system. The method comprises the following steps of: S1. initializing a test system and determining a test line; S2. simulating and determining a first relation curve and a second relation curve when a train runs on the test line, wherein the first relation curve is a relation curve of the rotating speed and the time of a traction motor, and the second relation curve is a relation curve of the torque and the time of the traction motor; S3. operating an accompanying system according to the first relation curve, operating a tested system according to the second relation curve, and detecting and obtaining detection data of each detection sensor of the tested system; and S4. generating a detection report according to the detection data. The rail transit traction system test method and system have the advantages that the test requirements of the traction system in actual line operation can be simulated, various working conditions such as acceleration, the uniform speed, coasting and braking in actual operation are simulated, the test of the traction system on various indexes such as the temperature and the energy consumption is met, the test process and the test device are simple, and the like.

Description

technical field [0001] The invention relates to the field of testing of rail transit traction systems, in particular to a test method and system for rail transit traction systems. Background technique [0002] The traction system of electrified rail transit requires a large number of tests in the process of research and development to verify the performance of the traction system, including the temperature changes of key components and the energy consumption of the traction system. Some simulation calculation methods for traction system tests are disclosed in the prior art, but they can only be tested for certain specific parameters, and there is no way to conduct simulation tests for the actual train running lines. The test process and test equipment are complicated and the energy consumption is high. . Therefore, it is very necessary to study the test method and test equipment of rail transit traction system. The patent application number is 20020016195.4, and the name i...
