Abstract

The invention discloses a novel wind powered generator control method and a controller, wherein the method comprises the following steps: sampling input signals by a sampling circuit; conveying results to the controller for maximum power tracking algorithm calculation; outputting pulse waves to a driving circuit; driving a CUK circuit by the driving circuit after processing the received pulse waves so that the equivalent impedance of the CUK circuit per se and a load can be regulated; and finally, outputting the maximum power capable of being output at the time by the wind powered generator. The controller of the invention comprises a sampling circuit, a control circuit, a driving circuit and a CUK circuit, wherein the output end of the sampling circuit is connected with the input end of the control circuit, the output end of the control circuit is connected with the input end of the driving circuit, and the output end of the driving circuit is connected with the input end of the CUK circuit. The method of the invention utilizes the maximum power tracking algorithm so that the wind powered generator controller can track the catchable maximum wind energy under the complicated external environment condition, and the power generation efficiency of a generator can be effectively improved.

Description

technical field [0001] The invention relates to automatic control technology, in particular to a novel wind power generator control method and controller capable of tracking the maximum power of wind energy. Background technique [0002] In recent years, the production and promotion of off-grid wind turbines in my country have made great progress. As of 1997, the number of off-grid wind turbines promoted and applied nationwide has exceeded 100,000 units, with a total installed capacity of more than 15MW, which has solved the power consumption problems of more than 130,000 households for lighting, watching TV, and listening to the radio. At present, the control function of domestic off-grid wind turbine controllers is relatively simple. The controller uses the voltage at both ends of the battery as the basis for charging and discharging the battery to control the charging of the battery; The unit is protected. The power output of the wind turbine is determined by the load, ...
