A research on the operational characteristics of WPT considering reliability limitation

This paper provides an applicable procedure to introduce wind power generaton into a weak power system for readers considering the fluctuation of electric current so as to determine the limit capacity. The static and dynamic condition of a Wind Power Turbine (WPT) relates to terminal output and connection system are detailly explained. Characters of inductive generator under sudden variation of wind speed and short circiut are analyzed. Wind and generation matrixes are applied for area´s wind condition. The method to determine optimal bus are discussed considering the particularity of load sytem. This paper also analyzed electric fluctuation on each bus of substation system. Limit capacity of renewable energy is tested refering the margin of power system.
