Wind turbine adaptive controller modeling

摘要

In the time of current trend of increasing energy consumption, the wind-power engineering may compensate considerable part of required electric energy. Rapid windpower engineering development is considered to be one of the important sources of human need satisfaction. Conventional wind turbine control strategies are dedicated to ensure high energy conversion efficiency under varying wind conditions. The challenge in wind power control engineering is to design an adaptive wind turbine control strategy, which provides the dynamic system stability and the effectiveness of energy conversion. Modern vector controlled wind turbine drives allow fast and accurate torque control on a wide speed range. The aim of this paper is to design and implement the control algorithm, which implies the electromagnetic torque control in order to adapt the optimal rotor speed and keep high energy conversion efficiency, taking full advantage of electrical drive performance. Wind turbine operation is considered in the partial-load regime. The stability of the purposed control system is studied using linear control theory concepts. The effectiveness of the wind energy conversion is proved by the simulation results in MATLAB Simulink environment.
