Abstract

The present invention provides a virtual track train semi-physical simulation system based on hybrid power, which is characterized in that it includes sequentially connected working condition models, train models, wheel models, gearbox models, motor models, inverters, auxiliary loads and CAN bus, and one end of the CAN bus is connected to the energy storage model through the DC bus, and the other end is connected to the energy management strategy model, and the energy storage model is connected to the energy management strategy model. Firstly, the backward simulation method is used to transmit the energy in the opposite direction , from the working condition model to the energy management strategy model, calculate the demand of each level step by step; then use the forward simulation method, according to the direction of energy flow transmission, according to the calculated demand of the energy management strategy model, from the energy From the management strategy model to the working condition model, the actual quantities at all levels are calculated step by step. The present invention combines two modes of backward simulation and forward simulation, which can reduce the error of simulation results.

Description

Technical field [0001] The invention belongs to the field of train simulation operation, and specifically relates to a virtual track train semi-physical simulation system based on hybrid power. Background technique [0002] With the development of my country's urbanization and regional urbanization, urban traffic has become uncoordinated among people, vehicles and roads. Deterioration of the transportation environment, environmental pollution, energy utilization, and noise have caused great pressure on the development of the city. Residents in the city and city groups around the city have put forward new requirements for convenient vehicles. Vigorously develop urban convenient transportation methods, especially high-efficiency transportation methods centered on urban rail transportation, is an effective countermeasure to ease the pressure on urban transportation. [0003] The self-guided rail train based on the virtual track is proposed under this general situation. It is a new t...
