用于牵引电机制动电能回收的双环校正控制策略

Double Closed Loop Corrective Control Method of Traction Motor Braking Energy Recovery

针对1 500 V地铁机车牵引电机的制动电能回收控制方案,根据牵引电机起制动时电能的变化建立了以供电网电压为外环,以充放电电流为内环的双环反馈控制的DC/DC变换电路数学模型,并对控制系统的稳定性能和响应性能进行了仿真验证。

The control scheme of DC/DC converter used to recycle metro traction motor regenerative power energy of 1 500 V power supply system was introduced, and set up its mathematical model,the model used the supply voltage as outer loop and charge/ discharge current as inner loop of the double closed feedback loop, the stability and response performance of the designed control system was validated by simulation.
