摘　　要：针对可变风速下风电场频率控制问题,将变速风力发电机(VSWT)的超速控制和变桨距控制结合起来提出了减载控制策略,该策略不仅可以存储电能来满足配电网的约束需求,而且有助于初次调频控制。根据VSWT在高风速下运行的比例来调整风力发电机的静态频率差系数,实现在功率约束下对配电网的频率控制。Aiming at the frequency control problem of wind frm under variable wind speed,a load shedding control strategy was proposed by combining the overspeed control and pitch control of variable speed wind turbine(VSWT).The strategy can not only store the electric energy to meet the constrained demand of distribution network,but also help the primary frequency control.According to the proportion of VSWT running at high wind speed,the static frequency difference coefficient of wind turbine can be adjusted,and the frequency control of distribution network can be realized under power constraints.
