To study the on grid wind turbine generator made in china, three types of horizontal axis three-blade wind turbine generator were researched. The design of wind turbine and the factors which influence the property of the wind wheel were studied. The mathematical model and operation principle of wind turbine with squirrel cage induction generator, doubly-fed induction generator and permanent magnet...
Fixed speed wind turbine generator system (WTGS) uses induction generator as wind generator. Besides some of its advantages, it suffers greatly to meet the requirements of new wind farm grid code due to the dependency on reactive power. Some flexible AC transmission systems (FACTS) devices have been proposed recently for compensating the reactive power of induction generator during network disturbances...
This paper presents the development of wind farm models for design and verification of centralized voltage and frequency control strategies. First, a detailed model of wind turbine with permanent magnetic generator is established in Pscad / EMTDC simulation tool, and then it is extent to a simplified wind farm. Second, an overall wind farm level control strategy is designed and tested. At last, real...
E.ON Netz new grid code requires the ability from the wind turbines to remain connected to the network when terminal voltage level drops to zero for at least 150 ms. Moreover, wind turbines must also contribute with voltage regulation during and after grid faults. A comparative study analyzing the dynamic behavior of conventional versions of wind turbines based on doubly-fed induction generator and...
