Abstract

Abstract: This paper proposes a two-stage control scheme of ‘no load - grid connected’ to realize the smooth state transferring from ‘no load’ to ‘grid connected’, according to the characteristics of ‘no load’ and ‘grid connected’ of doubly-fed induction generator （DFIG）. Based on the Matlab/Simulink platform, we establish the simulation models of a no-load operation and a grid-connected operation of DFIG respectively, and give the simulation module and parameters based on the stator field-oriented vector control technology, which provides important basic information and platform for the research on the grid connected control technology of DFIG. Then, we propose a set of the simulation experiment scheme for ‘no load - grid connected’ DFIG, which can obtain comprehensive results for testing the control strategies. Finally, we verify the effectiveness of the proposed control strategies and simulation model, through the simulation results of the no-load operation, the transient process at the cutting-in moment, and the maximum power energy tracking （MPPT） after grid-connected operation.

Key words: doubly-fed induction generator （DFIG）, no-load cutting-in, stator field-oriented control, maximum power energy tracking （MPPT）, modeling and simulation
