Abstract

Virtual Synchronous Control (VSynC) strategy for Doubly-Fed Induction Generator (DFIG) has attracted much attention because of its advantages in providing dynamic supports of frequency and voltage. In this way, most researches of VSynC strategy concentrate on analysis of its electromechanical behaviours, but pay little attention to its electromagnetic transient responses and fault characteristics, which may hinder its promotion in engineering application. This paper pays special attention to the electromagnetic transient behaviours of VSynC-based DFIG and proposes a voltage compensation VSynC strategy to implement fault ride through during symmetrical grid faults. The proposed strategy improves the transient response of existing VSynC strategy, capable of limiting the overcurrent in DFIG rotor circuits and suppressing the oscillations of electromagnetic torque. Simulation results validate the effectiveness of the proposed strategy.
