Subway traction system net voltage interruption, mutation and fluctuation testing system and method

Abstract

The invention provides a subway traction system net voltage interruption, mutation and fluctuation testing system and method, and relates to the railway train operation maintenance technical field; a real time simulation device in the system loads a preset subway vehicle electric model and a subway vehicle kinetic model; a host monitoring device adjusts parameters of the subway vehicle electric model and the subway vehicle kinetic model of the real time simulation device; the real time simulation device simulates subway vehicle loading conditions and subway traction system net voltage conditions in real time; a traction control device sends a traction control signal to the real time simulation device, thus driving the subway vehicle model in the real time simulation device to run in a testing requirement state; the host monitoring device adjusts the parameters of the subway vehicle electric model and the subway vehicle kinetic model of the real time simulation device and the net voltage conditions, thus carrying out a net voltage interruption test, a net voltage mutation test or a net voltage fluctuation test; the host monitoring device determines whether the net voltage interruption, mutation or fluctuation test have succeeded or not.

Description

technical field [0001] The invention relates to the technical field of rail train operation and maintenance, in particular to a system and method for testing network voltage interruption, sudden change and fluctuation of a subway traction system. Background technique [0002] At present, facing the country's strong support and construction of the subway, people's travel by subway has become a mainstream way of public transportation. Therefore, it is very important to conduct safety tests and maintenance on the subway system to ensure the safety of passengers. The influence of the subway vehicle by the voltage change of the external power supply is the content that the subway traction system must verify. The test items of the subway traction system include network voltage interruption, sudden change, and fluctuation. [0003] The network pressure interruption is in AW2 (a type of subway working condition, indicating that the subway vehicle capacity load is 6 people / m 2 ) lo...
