摘要: 针对城市轨道交通列车运行密度高,起制动功率大的特点,采用飞轮型再生制动能量回收装置可有效降低直流牵引网压波动,降低牵引能耗。由于该装置采用基于直流牵引网母线电压高低进行充放电的控制策略,在实际运行工况中可能存在无法准确识别再生能或储能设备SOC值无法自动调整导致无法再响应牵引网压波动的情况,本文提出空载网压识别和SOC自适应控制策略进行解决,通过轨道交通试验平台的试验验证,得出该控制策略的有效性。

Abstract: In terms of the high operation density and regenerative braking power of the urban mass transit, the flywheel energy storage system(FESS) can effectively reduce the DC traction network voltage fluctuation and the traction energy consumption. Because the charge or discharge operation for the FESS is just based on the high or low DC traction network voltage, so the regenerative braking power may not be identified accurately in addition, the state of charge (SOC) of the FESS cannot be automatically adjusted which leads to the incorrect response to the traction network voltage in the actual operating conditions. In this paper, the unload transit network voltage identification and the SOC optimized control strategy is adopted to solve these problem, the effectiveness of the proposed control strategy is verified by rail transit platform test.

Key words: urban mass transit, flywheel, regenerative braking, optimized control strategy
