Abstract: The present invention is concerned with a flexible way of operating a wind farm with a plurality of degrading wind turbine components. According to the invention, maintenance scheduling and power production in the wind farm are handled concurrently in a single optimization step. Instead of a serial approach first scheduling maintenance activities and subsequently adapting the power production and/or wind turbine operation the two aspects are optimized together. The wind farm operation takes maintenance aspects into account by adapting a life index or health status based on modeled mechanical and electrical stress. Accordingly, the wind farm owner may decide when and how much energy to produce accepting which level of stress to the turbine equipment. The proposed optimization of wind farm operation includes all aspects of transmission network operator settings, the topology of wind farms and the underlying collector grid, the short and long term wind conditions forecasts, the conditions of the turbines, the estimated remaining operational time under different usage patterns and times, as well as aspects of the electricity market.

Abstract translation: 本发明涉及操作具有多个降级风力涡轮机部件的风电场的灵活方式。 根据本发明，在单一优化步骤中同时处理风电场中的维护调度和电力生产。 代替串行方法首先调度维护活动并随后调整功率生产和/或风力涡轮机操作，这两个方面被一起优化。 风力发电场运行通过根据模拟的机械和电气应力调整生命指标或健康状况来考虑维护方面的问题。 因此，风力发电场所有者可以决定何时以及能产生多少能量来接受涡轮机设备的应力水平。 拟议的风电场运行优化包括传输网络运营商设置，风电场和底层收集器网格的拓扑结构，短期和长期风力条件预测，涡轮机状况，不同使用情况下的估计剩余运行时间 模式和时代，以及电力市场的各个方面。
