桨距控制 meaning in Chinese

blade pitch control

The result of computer and analysis based on blade elements theory shows us that we can regulate the rotate speed of wind turbine rotor by changing set angle and pitch h . variable - pitch system is the key component of the whole wind turbine , which can assure safely pitch - control and brake
本文利用叶素理论，经计算分析得出：通过改变风力机安装角可以改变桨距h ，从而改变风力机的转速。变距机构是变桨距控制型风电机组实现变距控制和安全刹车的关键机构之一，它的运动由平动和转动两部分组成。
Benefited from the ceaseless development of information technology and control technique , research on grid - connected wind power generation has been in fast progress , with commercial application from several kilowatts up to more than one megawatts per unit , and category of controls from stall type to pitch regulation type up to the state - of - the - art varying speed type
随着计算机与自动控制技术的飞速发展，风力发电技术的发展极为迅速，其单机容量从最初的数十千瓦级发展到最近进入市场的兆瓦级机组；控制方式从基本的定桨距失速型控制向变桨距控制直到最新的变速控制发展。
