摘要
列车正常运行过程中,不可避免会出现受电弓与接触网脱离接触的情况,就会造成供电电压中断,影响列车安全稳定运行。针对这一实际工程问题,提出一种依据采样计算网压基波电压的幅值、锁相环(PLL)相位差值及电流计算的综合检测及控制方法。该方法已经在1.8 MW高功率因数整流器上得到实现,并通过半实物仿真测试和地面联调试验验证了该方法的正确性与可行性.降低了因铁路恶劣供电条件造成的安全隐患。
During the normal operation of the train,it is inevitable that the pantograph will come out of contact with the catenary,which will cause the interruption of power supply voltage and affect the safe and stable operation of the train.Aiming at this practical engineering problem,a comprehensive detection and control method based on sampling to calculate the amplitude of voltage base wave,phase-locked loop(PLL)phase difference and current calculation is proposed.The method has been implemented on 1.8 MW high power factor rectifier,and the correctness and feasibility of the method have been verified by semi-physical simulation test and ground joint adjustment test,and the hidden danger caused by bad railway power supply conditions has been reduced.
