For the safe operation of urban vehicles under regenerative braking working condition on testing line, the energy absorbing equipment is required to suppress over-voltage. The analysis shows that resistor energy absorbing equipment is a low cost and reasonable choice to solve the problem of urban vehicles regenerative braking energy absorbing on testing line.From the induction motor model, the working principle of induction motor regenerative braking is analyzed in this paper. Combination of the principle of transit vehicle main circuit, the energy flowing of electrical drive system, the calculation of regenerative braking energy and the calculation of regenerative braking resistor are given. The main circuit as well as control circuit and control software of energy absorbing equipment has been completed. At the same time, chopper power module, filter inductor and chopper resistor are designed.The research and engineering design work are fully based on actual engineering requirements, including:●The research and engineering development of regenerative braking energy absorbing equipment for urban vehicle on testing line.●The analysis and calculation of the working condition of urban vehicle regenerative braking.●The principle simulation and test verification of urban vehicle regenerative braking energy absorbing equipment for testing line.Through the research and engineering design, regenerative braking energy absorbing equipment is provided to urban vehicle factory. The equipment could be applied in multi-voltage condition, not only having fault protection and self-diagnostic function, but also offering telemetry and remote communication capabilities to communicate with power supply substation automation system for integrated monitoring management.This paper has mainly adopted means of theoretical analysis and development. Through simulation and experiment, it has been verified that resistor energy absorbing equipment is a suitable solution for urban vehicle testing line.
