摘要:
对地面式储能系统与制动电阻联合工作时的阈值设定进行优化研究。以降低再生制动能量的线路损耗与稳定列车受电弓处牵引网压为目标，提出了一种根据列车最大制动回馈功率的阈值优化方法。采用地铁实际线路参数进行仿真，结果表明：阈值优化后，单车制动时再生制动能量回收率得到有效提升；多车制动时列车受电弓处网压得到抑制，避免再生制动失效情况的发生。
Abstracts:
Optimization of threshold of the stationary energy storage system and braking resistor is studied. In order to reduce the energy loss of regenerative brake on the line impedance and to stabilize the voltage of pantograph, a threshold optimization method based on maximum braking feedback power of train is proposed. The simulation is conducted by using actual line parameters of metro. The results show that the method can effectively improve the energy recovery rate of regenerative brake in the case of single-vehicle brake and can reduce the voltage of pantograph and avoid the failure of regenerative brake in the case of multi-vehicle brake.
