Fault Current Suppression Method for a Virtual Synchronous Type Grid⁃forming Energy Storage Converters
摘要
Abstract
The constant voltage output characteristics of grid⁃forming inverters result in overcurrent under fault con⁃ditions,which limits their application and promotion.In this paper,a fault current suppression method for a virtual synchronous grid⁃forming energy storage converter is proposed which,on the premises of achieving inertial enhance⁃ment,can limit the fault current.First,a control strategy is proposed based on the principle of virtual synchronous generator and its inertia enhancement effect is analyzed.Then,the reasons for overcurrent under fault conditions were analyzed.The inability to adjust power commands in a timely manner and the transient component of voltage drop are two main factors causing overcurrent.Moreover,a feedforward control strategy based on power compensa⁃tion and voltage compensation is designed,which can eliminate the impact of overcurrent under single⁃phase and three⁃phase faults.Finally,a MATLAB/Simulink simulation model is set up to verify the effectiveness of the fault cur⁃rent suppression method.关键词
