风力发电发展现状

Of the last century 70\\\\\\\\\\\\\\\'s, the worldwide capacity of wind power generation along the rising power equipment advances in power control technology continues to mature and flourish direction. Rational development and utilization of wind energy for our country and the world are of great practical significance. Wind Power System experienced a CSCF(constant speed constant frequency), VSCF(variable speed constant frequency), direct-drive phases. CSCF wind power generation system is characterized by simple structure, but Wind energy utilization rate is low; VSCF wind power system to maximize the improvement of the characteristics of wind energy utilization, but the complex structure of such a system, reliability is low;　Direct-drive wind power system, characterized by the absence Gearbox, system reliability, noise greatly reduced, but the motor bulky and costly. This article describes the status of wind power development at home and abroad.
