专利汇可以提供Wind power generator专利检索,专利查询,专利分析的服务。并且PURPOSE:To enable the optimal control corresponding with the wind speed by performing such load control as to obtain variable output corresponding with the input and to produce constant rotary speed upto the rated wind speed region while performing such load control as to produced constant rotary speed through function of a pitch control mechanism after said region. CONSTITUTION:Upon receiving of wind force to rotate a blade 12 and reach to the cut-in wind speed region, a rotary speed comparators 34 will produce an output for driving a phase control circuit 36. Said circuit 36 will drive a thyristor gate trigger circuit 39 on the basis of the output signals from a current detection circuit 37 and a frequency detection circuit 38 to perform such load control as to make the rotary speed of blade 12 constant. Upon entering into the rated wind speed region, the pitch angle of the blade 12 is controlled through function of a pitch control mechanism employing mechanical means provided in the rotor hab 13 of the wind receiving section 11 including the blade 12 thus to control the blade 12 with constant rotary speed.,下面是Wind power generator专利的具体信息内容。
