电压解耦矢量控制型交流牵引平台

针对大功率变频实验平台能耗大、对电网干扰大的问题,设计了一种电压解耦矢量控制型交流牵引仿真实验平台.采用转速、转矩分别独立控制实现牵引传动系统和动态负载转矩的模拟与控制.结合城轨动车交流牵引系统的参数,对实验平台的控制方案和控制性能进行仿真验证,分析了系统动态启动过程、能量回馈和系统平衡条件,仿真结果表明系统性能良好,为实物平台的搭建提供了理论依据和数据支持.

AC traction test platform controlled by voltage-decoupled vector control

AC Traction Motor Testing Platform based on voltage vector decoupling control is designed to solve energy consumption and power disturbance.Using rotor speed and load torque control separately,the dynamic load and AC propulsion system can be simulated and tested thoroughly in laboratory.The designed platform is modulated and simulated based on an practical AC propulsion system to analyze the starting progress,energy recovering and system balance condition.Simulation results prove that the designed platform ...
