一种公自转组合式风力发电系统的研究与设计

Research and Design of a Combined Rotation Wind Power System

由于地理环境和气候条件等因素的影响,导致风向的复杂多变,通过对传统风力发电系统的受风情况进行分析发现,部分风能未能得到有效利用,同时受到变应力的作用,影响设备的使用寿命。通过对风向的深入分析,对其进行结构创新设计,实现六面受风,在各种风向的情况下,都能达到风能的最大化利用,进一步提高风能的利用率;公自转组合设计,在变荷载的作用下可有效提高抗疲劳强度,增强抗风性能,增强风力发电系统的适应性。

Due to the influence of geographical environment and climatic conditions, the wind direction is complex and changeable. Based on the analysis of wind receiving condition of traditional wind power generation system, it is found that some wind energy cannot be effectively utilized and the service life of equipments are affected by the stress. Through the in-depth analysis of wind direction, the structure of wind power system is innovatively designed to maximize wind energy utilization under all wind directions, which can further improve the utilization of wind energy. The combination of revolution and rotation of wind power system can effectively improve anti-fatigue strength and enhance wind-resistance capacity of wind power system under variable wind loads, which can further improve the adaptability of wind power generation system.
