A wind turbine speed control system

Abstract

The invention belongs to the technical field of wind power generation, and particularly relates to a rotating speed regulating and controlling system of a wind driven generator. The rotating speed regulating and controlling system of the wind driven generator collects voltage sent by the wind driven generator through a collecting circuit in real time, and input real-time voltage is converted intooutput signals corresponding to the rotating speed of the wind driven generator through a collecting circuit. A single-chip microcomputer receives the output signals of the collecting circuit, the real-time rotating speed, corresponding to the output signals, of the wind driven generator is compared with preset rotating speed in the single-chip microcomputer, and when the real-time rotating speedis larger than the preset rotating speed, the single-chip microcomputer controls a stepping motor to rotate forwards through a control circuit; meanwhile, the stepping motor drives a paddle of the wind driven generator to rotate, the included angle between the paddle and the wind direction tends to be 89 degrees, and therefore the aim of turning down the rotating speed of the wind driven generatoris achieved.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a speed control system of a wind power generator. Background technique [0002] As lighting equipment, street lamps are widely used in areas such as suburban roads, tourist attractions, development zones, and expressways, and these areas are far away from low-voltage substations. In order to reduce lighting costs, wind power generation systems are usually used. However, the existing wind power generation system can only stop working when the wind speed is high, but cannot generate electricity; if it continues to generate electricity, the wind power generator will be damaged. Contents of the invention [0003] The object of the present invention is to: aim at the above existing problems, to provide a wind power generator rotation speed control system, which can still generate electricity normally when the wind speed is high, which ensures the need for l...
