A Novel Multi-functional Power Flow Control System and Its Control Strategy in Section Post for Electrified Railway
摘要
Abstract
The particular split-phase traction power supply system of electrified railways faces the challenges of low regenerative braking energy utilization and speed loss during passing phase-separation.To address these issues,this paper proposes a multi-functional power flow control system for section post(SP-MPFC)and its control strategy.This system aims to fully use the installation capacity of converters to achieve flexible uninterrupted phase-separation passing,traction network terminal voltage stability,and regenerative braking energy exchange.First,the structure of the proposed SP-MPFC is introduced,and the working principles of the different functions are analyzed in detail.On this basis,a hierarchical control strategy is proposed for SP-MPFC.The energy management layer determines the active and reactive power output references for each converter.The converter control layer coordinates the multiple converters to track the received power references quickly and accurately.Finally,simulations verify the effectiveness of the proposed SP-MPFC and control strategy.关键词
