海上风电机组降载方法综述

摘要

风合理利用风电机组特性和控制效果，并通过不同的策略达到同时降低海上风电机组气动和水动载荷特别是疲劳载荷，可以达到优化基础和支撑结构的目的。不同的降载方法有不同的适用性和优缺点，使用某种降载方法时同时会对子系统造成一定影响。发电量不是作为判别降载方法是否有效的唯一判定标准，合理考虑各个子系统以及整机的经济能效比才是合理的做法。%　　By using wind turbine characteristics and control effects and using different strategies to reduce ofishore wind turbine pneumatic and water dynamic load, especially fatigue load, the foundation and support structure can be optimized. Different mitigation methods have different applicability and advantages and disadvantages, and must consider the impact to the subsystem. Generating capacity is not the only criteria to determine a valid method, and the reasonable approach is to consider the various subsystems, as well as the energy effciency of the whole economy.
