Analysis of DFIG-based wind generation LVRT control strategy
摘要
Abstract
In order to facilitate the recovery of power, when the grid voltage drops in a certain range, the wind generator not only needs to protect the rotor side converter, but also should provide reactive power to the grid. This paper takes DFIG for an example. In order to protect the rotor side converter, it analyzes DFIG's electromagnetic transition process aroused by different voltage phase angle while the grid voltage drops. A control strategy to eliminate harmonic components during transition process is proposed. Simulation results show that the control strategy can not only achieve the purpose of protecting the rotor side converter, while eliminating the harmonic currents of stator side and rotor side when voltage drops. But also provide reactive power to the power grid.关键词
