Experiences with Model Predictive Control for the W2E-120/3.0fc

摘要

This contribution presents a Model Predictive Controller (MPC) with move-blocking strategy for combined power leveling and load alleviation in wind turbine operation The controller is designed for a 3 MW wind turbine developed by W2E Wind to Energy GmbH and compared to a baseline controller, using classic control schemes, which currently operates the wind turbine. All simulations are carried out using a detailed multibody simulation turbine model implemented in alaska/Wind. The performance of the controllers is compared using a 50-year Extreme Operation Gust event, since it is one of the main design drivers for the wind turbine considered in this work. The implemented MPC is able to level electrical output power and reduce mechanical loads at the same time. Without derating the achievable control results, the move-blocking strategy reduces the computational burden by more than 50% compared to a baseline MPC and allows to run the MPC on a state of the art Programmable Logic Controller (PLC).
