Method and system for controlling a wind power plant comprising a number of wind turbine generators
摘要：
This invention relates to a method and a system for controlling a wind power plant to deliver power to the power network. A frequency of the power network is detected. A variation rate in the detected frequency of the power network is calculated. A requested variation of delivered power for the wind power plant is calculated based on a value of the inertia of the wind power plant and the calculated frequency variation rate. A requested variation of delivered power for each wind turbine generator of the wind power plant is calculated based on the calculated requested variation of delivered power of the wind power plant and a current power level of each wind turbine generator. The resulting calculated requested power variation is then used for controlling each wind turbine generator to deliver power to the network.
摘要（中）：

本发明涉及一种用于控制风力发电厂向电力网络输电的方法和系统。 检测到电力网络的频率。 计算电力网检测频率的变化率。 根据风力发电厂的惯性值和计算出的频率变化率，计算出风力发电厂输送功率的变化。 基于所计算的风力发电厂的输送功率的要求变化和每个风力涡轮发电机的当前功率水平来计算风力发电厂的每个风力涡轮发电机的所需变化的输送功率。 然后，所得到的计算的所请求的功率变化用于控制每个风力涡轮发电机以向网络输送功率。
