WIND POWER PLANT CONTROL SCHEME

A control system, for controlling a flow of wind through a wind power plant comprising a plurality of wind turbine generators, comprising: a first controller, local to the wind power plant, configured to: receive operational data relating to the wind power plant and, in 5response, to send control signals to the plurality of wind turbine generators based on an implemented wind power plant control function, and a second controller. The second controller is configured to: receive operational data from the wind power plant; train a wind power plant model using the received operational data; generate a trained wind power plant control function based on the trained wind power plant model; and transmit the 10trained wind power plant control function to the first controller. Following the transmission of the trained wind power plant control function to the first controller, the first controller is further configured to: update the wind power plant control function with the trained wind power plant control function. The invention has particular utility in the context of controlling the flow of wind through the wind power plant, for example by controlling the wake steering 15and/or axial induction factor of the wind turbines in the power plant. A complex dynamic relationship exists between the control actions of wind turbines and the resultant wind flow through the power plant which is difficult to control accurately through conventional control approaches. The invention implements a machine learning approach to improve the operational performance of the control function over time, thereby to optimise the flow of 20wind through the wind park by controlling the yaw offset/axial induction factors of the wind turbines, which may achieve improved power production. L'invention concerne un système de commande, pour commander un flux de vent à travers un parc éolien comprenant une pluralité de générateurs éoliens. Ledit système comprend : un premier dispositif de commande, local au parc éolien, configuré pour recevoir des données opérationnelles relatives au parc éolien et, en réponse, pour envoyer des signaux de commande à la pluralité de générateurs éoliens sur la base d'une fonction de commande de parc éolien mise en œuvre, et un second dispositif de commande. Le second dispositif de commande est configuré pour : recevoir des données opérationnelles provenant du parc éolien ; entraîner un modèle de parc éolien à l'aide des données opérationnelles reçues ; générer une fo
