Controlling method for wind power generator
专利汇可以提供Controlling method for wind power generator专利检索，专利查询，专利分析的服务。并且PURPOSE: To maintain a high energy acquisition rate by setting a given relation between the number of revolutions and output to an algorithmic combination of a fixed peripheral speed ratio control, where a windmill power coefficient holds a high value, with a load control, where variation of the number of revolutions is held within a given tolerance.
CONSTITUTION: An output of a windmill 1 is converted into electric power by a motive power-electric power converter 2 composed of generator and frequency converter. An output command generator 5 outputs an output command corresponding to a number of revolutions of rotor of the windmill 1 detected by a rotating speed sensor 4 and gives a deviation of output signal P from output command to the motive power electric power converter 2. In this case, a maximum output control is performed at every number of revolutions while a wind velocity is from cut-in velocity to rated one,an output P is kept constantly while the wind velocity is from rated velocity to cut-out one, and the number of revolutions is controlled within a certain tolerance by a mechanical pitch control.
