Soekrutin foer Optimering av Effekten i ett Vindkraftverk med Variabelt Varvtal (Search Routine for Optimization on the Power in a Wind Power Plant with Variable Speed)

摘要

To get a wind power plant with variable speed to deliver maximum power at actual windspeed it is important that the speed of the turbine is correct. The paper describes a method how to obtain this, by optimization of a parameter of amplification, KQ, in the electrical control of the power plant. A model of the wind power plant and the optimizing algorithm have been designed and implemented in the simulation language Simnon. The optimization algorithm works in the following way. Add a test signal to KQ so that a power variation is obtained. Estimate the crosscovariance between the test signal and the power variation. The result of the estimation is then used to adjust KQ to its optimum.
