该文基于具备低电压穿越能力的风机在部分电压扰动场景下仍无法成功穿越的场景分析,研究提出风电场内双馈风机可用无功与异步风机无功负荷的协调控制策略.该策略通过列写各风机的电压约束方程并在二维平面上求解可行域,得出最小脱网台数下的无功增发与切机策略,实现多场景电压扰动下风电场低电压穿越能力的进一步挖掘提升,通过对实际风电场的仿真分析,验证了所提策略的有效性.“,”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.
