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...
With rapid development of wind power generation, large capacity wind farms are connected into the transmission system. Comparing with traditional power plant, the transient characteristics of transmission grid including wind farm are worthy investigating. The wind farm based-on wound rotor induction generators (WRIGs) shares high market occupancy in China, but academic researches on this grid-connected...
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 security 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). In the paper, the model...
In an AC/DC large-scale interconnection power grid, there are many problems to be solved. Among these, small- signal stability is extremely important. In this paper, based on the reallocating -damping theory of PSS, reallocating-damping theory of HVDC modulation is proposed, that variation of gain of HVDC modulation doesn't influence the system general damping. It is also proved that reallocating-damping...
