Due to the asynchronous generator has many negative factors such as large power fluctuation, poor transient performance, low energy efficiency, etc. The doubly fed induction generator(DFIG) is becoming a popular concept and thus the modeling of DFIG becomes an interesting research topic. This paper develops the DFIG model of power flow and third-order transient in which the power converter is simulated...
With wind farms expansion, the wind generations have large influence on power grids. Taking wind farms connecting to the grids as an object of study, this paper set up dynamic mathematical models of asynchronous wind power system, including wind speed, wind turbine, transmission mechanism and asynchronous generator. And set up the dynamic simulation model of asynchronous wind power using Power System...
It is expected that increasing amounts of new generation technologies will be connected to electrical power systems in the near future. Most of these technologies are of considerably smaller scale than conventional synchronous generators and are therefore connected to distribution grids, as the DFIG-based wind farm. When connected in small amounts, the impact of wind farm on power system transient...
Based on simplified RX model of asynchronous generator, state estimation model containing wind generators is presented in this paper. Simplified RX model can be merged into traditional state estimation algorithm efficiently with the consideration of asynchronous generator and the impact of wind generators on power system state estimation is investigated. Compared with traditional RX model, the calculation...
Increasing capacity of connected wind power generation to utilities brings new opportunities and also problems to the utilities and customers. Evolution and analyzing of the connection conditions and effects of wind farms especially on remote areas are the main aspects of developing wind power on the utilities, because the impact will be more serious. The problem is that these wind turbine that mostly...
