摘要:
动车组牵引四象限变流器输出直流电压存在二倍工频波动、四象限电流含有较多等效开关频率的纹波,对电压和电流检测时常采用硬件滤波电路或数字滤波器进行信号调理,但滤波参数设计不合理会导致控制系统不稳定。为提高 400 km/h 高速动车组四象限变流器控制稳定性,首先介绍四象限变流器“电压—电流”双闭环控制参数设计原则;其次重点分析电压、电流采样通道叠加滤波环节对闭环控制稳定性的影响,揭示双闭环系统稳定的条件;最后,基于 400 km/h 高速动车组的仿真结果验证了理论分析的正确性和有效性。
Abstract:
Double-grid-frequency fluctuation exists in DC-link voltage of EMU 4QS-converter whose grid-side current containsmuch ripple of equivalent switching frequency. RC circuit filters and digital filters were usually employed for signal conditioningof voltage and current. However, improper filter parameter will lead to unstable control. In order to improve control stability of 400 km/hhigh-speed EMU, firstly, the parameter design principle of DC-link voltage and current double-loop control for a 4QS-converter wasintroduced. Secondly, the effects of voltage and current signal conditioning filters on the stability of the double-loop control wereanalyzed, and the necessary conditions of system stable were revealed. Finally, simulation results based on 400 km/h high-speed EMUverifiedied the correctness and effectiveness of the theoretical analysis.
