摘要/Abstract

摘要： 串联式混合动力车辆在大功率加载过程中存在发动机超载灭车的问题。为实现机组平顺调节，分析发动机-发电机组在调节过程中失稳的原因，提出一种新型发动机-发电机组协调控制策略，优化机组的协调方法，减小机组动态调节过程中系统的能量损耗，改善车载综合电力系统母线的电能质量。硬件在环仿真实验结果表明：相比传统的控制策略，新型策略可以实现动态调节过程最小能量损耗，平抑直流母线电压波动，协助发动机-发电机组更好地执行整车能量管理策略。

Abstract: In the process of high-power loading，the flameout of series hybrid electric vehicle may be due to engine overload. In order to realize the smooth adjustment of engine-generator set，the reasons for the instability of engine-generator set during the adjustment process are analyzed，and a coordinated control strategy of engine-generator set is proposed，and the coordination method of engine-generator set is optimized. The energy loss of the on-board integrated power system during the dynamic adjustment of engine-generator set is reduced，and the power quality of bus in on-board integrated power system is improved. The hardware-in-the-loop simulation test shows that，compared with the traditional control strategy，the proposed strategy can achieve the minimum energy loss during the dynamic adjustment process，smooth the DC bus voltage fluctuation，and assist the engine-generator set to better implement the vehicle energy management strategy.
