应用 STATCOM 的 DFIG 风力发电机低电压穿越能力分析
Analysis of low voltage ride through capability of double fed induction generator with STATCOM
摘要
Abstract
To improve the low voltage ride through(LVRT)capability on double fed induction generator (DFIG),we developed a double closed-loop feedback control strategy combining voltage outer loop with current inner ring on the basis of STATCOM,and verified its effectiveness through simulation.In the simulations,STATCOMs were respectively installed at the terminal of wind generator,the high voltage side and the low voltage side of common coupling point.And then different depths of voltage drop were added to the grid,and different compensation effects were compared and discussed.Experimental results suggest that the compensation effect is the best when STATCOM is installed at the wind generator terminal.When the voltage drops,STATCOMs can provide power grid with reactive power quickly,raise the voltage of the wind turbine generator,and improve the LVRT capability of wind farms.In the aspects of STATCOM output reactive power and rising percentages of wind farm terminal voltage, the compensation effect of STATCOM is significant for different depths of voltage drop.关键词
