Title:
WIND FARM AND METHOD AND CONTROLLER FOR FEEDING THE SAME
Document Type and Number:
WIPO Patent Application WO/2018/076236
Kind Code:
A1
Abstract:
A method for feeding a grid by a group of wind turbines (WT1, WT2, WT3, WT4, WT5) in a wind farm and controller (10) and wind farm using the same is provided. The method includes: (a) obtaining first real-time SCADA data and first real-time constant variables concerning each of the wind turbines (WT1, WT2, WT3, WT4, WT5) in the group for a first time point, and first calculating fatigue degree of the wind turbine using the obtained first real-time SCADA data and the first real-time constant variables thereof; and (b) first distributing the grid load among the wind turbines (WT1, WT2, WT3, WT4, WT5) in the group using the calculated fatigue degrees thereof. By having the solutions as mention above, during the operation period of "Crack Generation", it provides output data indicative of a load distribution among the wind turbines (WT1, WT2, WT3, WT4, WT5) of the wind farm in relation to the fatigue degrees of the wind turbines (WT1, WT2, WT3, WT4, WT5). This allows achieving an optimal load distribution among the wind turbines from time to time (i.e. at each execution cycle thereof) always taking into account the fatigue degrees of the wind turbines (WT1, WT2, WT3, WT4, WT5), which represent the operating conditions of the wind turbine prior to occurrence of defect. During "crack generation" operation period of wind turbines, this is helpful for controlling in a mode designed based on fatigue minimization so as to postpone defect occurrence as much as possible which is able to extend lifetime of wind farm with fixed capital cost.
