    Abstract: The invention relates to a method for controlling injection and absorption of reactive power in a wind power plant (WPP). In addition to wind turbine generators (WTG), the wind power plant comprises reactive power regulating devices, such as MSU and STATCOM devices. The reactive power regulating devices are controlled by wind power plant controller so that the combined amount of reactive power produced by the wind turbine generators and the reactive power regulating devices satisfies a desired amount of reactive power. In case of communication fault between the power plant controller and one of the reactive power regulating devices, the power plant controller is reconfigured so as to compensate the capability of the reactive power regulating device to inject or absorb the amount of reactive power.

    Abstract: This invention relates to a method and a power plant controller arranged to carry out the method. The method is on an intelligent dispatching of the power production to wind turbines and optional compensation equipment of a wind power plant, as the power producing units of a wind power plant. The invention relates to a case where the requested produced power is less than the total capacity of the power plant, and the invention relates to utilizing this situation to dispatch set points to the wind turbines and the compensation equipment in a flexible way. This flexibility may increase the wind turbines' life time, help in scheduling maintenance and expand the electrical operating range of the wind power plant. The determination of the set points on active and reactive power is a combined determination of both set points for each of the energy producing units of the wind power plant.

    Abstract translation: 本发明涉及一种布置成执行该方法的方法和电厂控制器。 该方法是对风力发电厂的风力发电机组和风力发电厂的发电机组的可选补偿设备进行智能调度。 本发明涉及所请求的生产能力小于发电厂的总容量的情况，本发明涉及利用这种情况以灵活的方式将设定点分配给风力涡轮机和补偿设备。 这种灵活性可能会增加风力发电机的使用寿命，有助于安排维护和扩大风力发电厂的电气运行范围。 有功和无功功率的设定点的确定是对风力发电厂的每个能量产生单元的两个设定点的组合确定。
