Variable speed constant frequency (VSCF) wind power generation system Adaptive Control Method
Abstract：Rapid growth in energy consumption in today's society, leading, growing energy crisis, while also becoming increasingly serious environmental pollution problems, so use renewable clean energy to replace the current fossil energy by the people as the solution to the energy crisis and environmental pollution problems of the most effective pathway, while the wind as a renewable clean energy storage in large, easy to use energy, large-scale use by the people, so how to generate electricity using wind energy wind power technology has become the current renewable energy research hotspot. In this paper, reading a lot of wind power at home and abroad on the basis of relevant literature, the design brief introduction VSCF wind power generation system of automatic control, in accordance with the relevant literature describes, first expounded VSCF wind power technology advantages, discusses today's shifting constant frequency wind power generation system has an important role in promoting. Second, a simple analysis of VSCF wind turbine works, the last from the perspective of a wind turbine control automatically catch the wind principle, through its mathematical model and the curve analysis, to understand the basic steps of their work, and how to implement automatic catch the wind process.
