摘要
介绍了动车组变流器中间直流电压保持模式的特点及应用工况,提出了基于矢量控制的中间直流电压保持控制策略,从理论上分析了控制策略中前馈补偿对控制的影响,给出了前馈功率的计算方法。最后通过试验结果验证了控制策略的有效性。
The characteristic and application of DC-link voltage hold mode for EMUs converter were introduced,and the DC-link voltage hold control strategy based on vector control was proposed.The influence of feed-forward compensation in control strategy was analyzed theoretically,and the calculation method of feed-forward power was provided.Finally,the validity of the control strategy was verified by the experiment results.
