一种风电机组在低风速区间的功率控制方法
A power control method of wind turbines in low wind speed area
摘要
Abstract
Wind velocity alters rapidly and the density of wind energy is lower in low wind speed area, which greatly affect power conversion efficiency of wind turbines. Aimed at enhancing wind turbines efficiency of power output, MPPT is adopted to capture maximum wind power from the perspective of power control according to operating peculiarity of wind turbine in low wind speed area. On the basis, a control strategy of fast focusing optimal rotating speed in wide range is simple, highly accurate and quicker to achieve optimal solution compared with conventional climbing method. Simulation in Power Simulation (PSIM) shows that this control strategy has a certain value for improving wind turbine stability and power conversion efficiency.关键词
