Research on Asymmetric Fault Ride-Through Control Strategy of Low Voltage Distribution Areas Flexible Interconnection System
摘要
Abstract
The low voltage distribution areas flexible interconnection system should be equipped with AC fault ride-through capability to ensure the reliable operation of the system under the short-circuit fault of the AC port.Therefore,an asymmetric fault ride-through strategy based on low voltage distribution areas flexible interconnection system is proposed.Firstly,the topological structure and control strategy of low voltage distribution areas flexible interconnection system are introduced.Secondly,the influence of grid-side voltage imbalance on the flexible system is analyzed,and a sequence separation control method is presented.Then,a fault ride-through control strategy considering port current control and system active power balance is proposed.Finally,the effectiveness of the proposed strategy is verified by simulation.关键词
