METHOD OF CONTROLLING A VARIABLE SPEED WIND TURBINE GENERATOR

摘要

In a method of controlling a variable speed wind turbine generator connected to a power grid and comprising means for controlling the generator speed, said method comprises the steps of - measuring the frequency f of the power grid, - controlling the speed of the generator for optimizing the power delivered to the power grid, - setting limits for the generator speed. The setting of the limits for the generator speed is performed in dependency of the measured frequency of the power grid. This provides a dynamical set of limits providing improved possibilities of optimizing the power production.
