As a clean renewable energy, wind energy draws more and more attention around the world. In case of high wind speed or low speed but substantial installed wind power capacity, wind turbine generators (WTGs) will take the place of traditional power plant partly. Under the circumstance, the transient stability will change. Therefore, in this article, the synthetical dynamic model of WTG is introduced...
With rapid development of wind power generation, the large capacity wind farms are built up and integrated into transmission network. The effect of wind farms on the grid becomes more serious and more extensive. In order to investigate the dynamic performances of the grid-connected wind farm and the interaction of the wind farms, it is necessary to present the appropriate models of wind farms, which...
This article is concerned with the impact of large-scale wind farms utilizing double fed induction generator (DFIG) on the transient stability to a general power system. In the first instance, the synthetical dynamic model of the wind turbine generators (WTGs) is introduced, including pitch angle control model and the generator protective model. And then, the simulation is made to the CIGRE B4-39...
The paper studies reactive power compensation strategy of wind farm based on optislip wound rotor induction generators (WRIGs). The WRIGs wind farm shares high market occupancy in China, but academic researches on this grid-connected wind generation are few. Due to the WRIGs wind turbines not allowing the control of the reactive power, so it is necessary that reactive power compensation device is...
With rapid development of wind power generation, it's necessary to study the dynamic characteristics of wind power generators when a fault occurs in the grid to assure the safe and stable operation of the wind farm. At present, the widely used wind power generators in the whole world are squirrel cage induction generator (SCIG) and doubly fed induction generator (DFIG). The models of SCIG wind power...
