Research on charge and discharge control strategy of hybrid power supply system for energy storage tram
The existing control logic of the energy storage tram hybrid power supply system needs multi-level processing,and the transmission path is complex.In this paper,taking a four-module 100%low-floor energy storage tram as an example,a charge and discharge control strategy of hybrid power supply system controlled by train control and management system(TCMS)is proposed,that is,the state data of each system are summarized by TCMS,and the charge and discharge actions of each system are controlled as a whole to realize the direct control of charge and discharge under different working conditions.The charge and discharge control strategy is verified.The results show that the control strategy can achieve the expected functional effect.The amount of communication data can be reduced by 88.24%,and the calculation and transmission time of control instructions can be saved by 33.33%,which improves the timeliness and economy of train operation.
