基于风机主动控制的风电场低电压穿越能力深度挖掘研究
Study on Deeply Improving Low Voltage Ride Through Ability of Wind Farm Based on Wind Turbine Active Control Strategy
摘要
Abstract
In order to deeply explore the low voltage ride through ability of wind farm,based on the analysis of wind turbine having low voltage ride through ability still failing to ride through under some voltage disturbance scenarios,a new wind turbine active control strategy and its intelligent upgrade solution were put forward.By solving voltage constraint equations of all wind turbines in the two-dimensional plane,reactive power setting and load shedding ratio can be obtained,thus available reactive power in double-fed induction generator (DFIG) and reactive power load of induction generator can be compatibly controlled.By means of this work,a novel thought can be provided for further improving low voltage ride through ability of wind farm.The proposed method is validated by actual wind farm simulation results.关键词
