双有源桥变换器短路故障穿越策略研究
Research on Short-Circuit Fault Ride-Through Strategy of Dual Active Bridge Converters
摘要
Abstract
Dual active bridge(DAB)converters has been widely applied in marine power systems to realize the energy conversion among storage batteries,dc buses and loads.As power supply units connected to the power distribution networks,DABs play an important role in the short-circuit protection.This paper focuses on the fault ride-through control of DAB converters under load-side short-circuit faults.According to the equivalent circuit under short-circuit conditions and the operational characteristic of DAB,a control scheme including an outer dc-bus voltage loop and an inner load current loop is proposed.Under the short-circuit fault,the outer voltage loop is saturated and the inner current loop is automatically switched to the constant-current control.After the completion of capacitor discharge,the DAB keeps supplying the short-circuit current to the fault point,ensuring the tripping of protective devices.The simulation results verify the feasibility of proposed strategy.关键词
