Method, system and device for on-line computation of optimal gain of wind generation set control strategy

The present invention is optimum gain line calculation method, system and wind turbine equipment on control strategy, on-line calculation method comprising the steps of: collecting real-time temperature of the external environment wind turbine; reads the system time; time reading system according to obtain the real-time temperature history of the month and monthly average temperature weighted calculation, the weighted temperature; air density is calculated according to the weighted local temperature and altitude; the air density, wind turbines binding parameters calculated optimum gain value. The present invention may be measured in real time the peripheral ambient temperature of wind turbine, according to the monthly average temperature history statistical weighting to calculate the air density, and binding characteristics of wind turbines, calculated online power full power speed of the speed torque control strategy the optimum gain values ​​of the wind turbine for online optimization, in order to improve performance of wind turbines, the present invention is relatively easy to implement and low cost, is conducive to the promotion.
