摘　　要：针对分布式和微电网系统要求小型风力发电机组的发电负荷可调的需要，提出一种小型水平轴风力机可变偏心距主动侧偏式功率调节方法，介绍机构的组成，分析改变偏心距使风轮侧偏产生机理，给出偏心距与风轮侧偏角度的表达式。通过改造1．5kW上风向水平轴风力机，在风洞中进行稳态风的变偏心距风力机功率输出特性实验，结果表明该机构可满足水平轴风力机功率调节的主要要求，为进一步将该机构用于商用小型风力机功率调节奠定了理论和实验基础。When small wind turbines are used in distributed power generation system and micro-grid system, the output of the turbines needs to be adjustable. This paper presents a small horizontal axis wind turbine with variable eccentricity mechanism which is used to control power output. The paper analyzes the way to change the eccentricity of the turbine cornering mechanism. An expression of the eccentricity and the furling angle of the turbine is derived. By modifying a 1.5 kW wind turbine, the variable eccentricity mechanism is added between the generator and the tail of the turbine. The power output characteristics are tested in a wind tunnel. The results demonstrated that this method has the high possibility to meet the requirements of the power control of commercial small wind turbines.
