The impact of the wind electric installations of variable rotation speed with doubly fed asynchronous generators on frequency regulation in electric systems (EES) is considered. Model of the research is developed in the programming complex Power Factory DIg SILENT GmbH, the results of frequency change modeling on the change of various portion of loading are given. This generalized model is recommended to use for the determination of the frequency change in EES with wind electric installations of the variable rotation speed and doubly fed asynchronous generators.
