Pitch control and load optimization of variable speed variable pitch wind turbine
摘要
Abstract
The issue that how to reduce system overshoot and decrease wind turbine load for large variable speed variable pitch wind turbine over the rated wind speed is discussed. Because the wind turbine is strongly nonlinear, the pitch control strategy based on fuzzy-immune-PID controller is adopted to reduce generator speed fluctuation and improve power quality. Aiming at how to decrease the tower fore-aft vibration, tower side-side vibration and gearbox vibration of the wind turbine, corresponding control strategies such as pitch and torque damping filter and acceleration feedback are proposed. Finally, this paper uses Bladed external controller module to program and simulate. It's shown that the proposed control strategy can improve the dynamic characteristics of variable pitch control and reduce the load of key parts.关键词
