A wind turbine forward-looking cooperative main control system and method based on a wind field flow field digital twin

Abstract

The present application relates to the technical field of wind power generation control, and particularly discloses a wind turbine forward-looking cooperative main control system and method based on wind field flow field digital twinning, which collects macro weather and micro flow field data through a multi-source heterogeneous data perception module, constructs a high-precision wind field flow field digital twinning engine and a wind turbine high-fidelity twin, realizes the advanced prediction of the wake distribution in the wind field and the dynamic response of the wind turbine, and fuses the space-time data through a forward-looking cooperative optimization control module, solves a multi-objective optimization function containing the maximum of the total field power generation and the minimum of the wind turbine fatigue load based on a model predictive control algorithm, and generates an optimal cooperative control strategy. Through the closed-loop control mechanism combining feedforward and feedback, the present application effectively solves the problems of large load impact and serious wake interference caused by the hysteresis of the traditional control strategy, and significantly improves the operation efficiency, safety and economy of the wind farm.
