风力发电实验仪

Experimental apparatus for wind power generation

研制了风力发电实验仪,并利用该实验仪探究了风速、风机转速、发电机输出电动势之间关系,测量了风机的风能利用系数,展示了风力发电涉及的工程技术问题,即:在额定风速之下,采用追踪最佳叶尖速比的调节方法可最大限度利用风能;当风速超过额定风速,用变浆距调节方法可实现风力发电平稳输出.

Experimental apparatus for wind power generation was designed. Using the apparatus, the relation between wind speed, fan rotation speed and the output of electromotive force was explored, the power coefficient was measured. Using this experimental apparatus, engineering problems involved in wind power generation were investigated, i. e. , under the nominal wind speed, tracking the optimum tip speed ratio could maximize the usage of wind; when the wind speed exceeded the nominal speed, the oitch distance adjustment method could achieve a steady output.
