Low Voltage Ride-through Analysis and Control for Doubly Fed Wind-Power Induction Generator Using Finite State Machine Method

Abstract:

Low Voltage Ride through (LVRT) technology of Doubly Fed Wind-Power Induction Generator (DFIG) is a very important issue for grid-connection of wind power system. The paper analyzed and simulated dynamic response of DFIG under balanced and unbalanced gird voltage dip. Then proposed a whole set of LVRT control strategies based on finite state machine method for DFIG and carried out a detailed experimental validation on a 22KW DFIG driving system test platform on balanced grid voltage dip, which was connected to a voltage-dip generator. The experimental waveforms indicated that the proposed control strategy could effectively met LVRT requirement under different dip depth and time.
