Research on passivity-based power control of PWM rectifier in urban rail traction power supply system
摘要
Abstract
At present, multi-pulse rectification way is applied in urban rail traction power supply system.However, there are some disadvantages which include the serious harmonic pollution and the energy that cannot flow in both directions.In view of the above problems, this paper puts forward a rectifier control method based on passive control strategy.For this kind of control mode, firstly, according to the topology structure of the main circuit of the voltage rectifier, the EL model of the system is established in two-phase synchronous rotating coordinate.The decoupling control strategy is used to design the controller.Finally, the strategy is used in the urban rail traction power supply system to control the voltage of the rectifier output contact network (rail).On this basis, the performance of the rectifier is analyzed under the conditions of load disturbance, locomotive braking and grid unbalance.The simulation results show that the rectifier performs well at stability, anti-jamming, unit power factor operating characteristics.This paper provides a good theoretical basis for urban rail traction power supply system.关键词
