Abstract

Abstract: Establishing a grid connection model of doubly-fed induction generator based wind turbine (DFIG) could be useful in the research and verification of black-start strategy in isolated power grid containing wind power. A DFIG grid connection simulation method based on Simulink was proposed. Through analyzing the operation characteristics of doubly-fed induction generator in no-load and grid-connected conditions, its dual-operation simulation model was established. According to the grid-connection theory of DFIG, the established doubly-fed induction generator model was combined with wind turbine, converter and other built-in modules, and the DFIG grid connection model was built with its control system added. Simulation results show that the simulation method is feasible.

Key words: isolated power grid black-start, electromagnetic transient, DFIG, grid connection, dual-operation simulation model
