供并网专用变桨风力发电机

1.一种由公司自主研发的用于中、小型风力发电机叶片的高精度调控离心机械自动变桨轮毂。

1. A company independent research and development for high-precision control of the small wind turbine blades centrifugal machinery automatically change the paddle wheels.

该变桨轮毂是根据发明技术（小型风力发电机离心变桨稳速轮毂，201210029960.1）和实用新型201120350092.8（已授权）研发而成，采用叶片轴与主轴不在同一平面的方式，使得重锤能置于变桨轮毂内部，便于小型化和密封。

The pitch wheel is a steady speed wheels according to the invention of the patented technology (small wind turbines, centrifugal pitch, 201210029960.1), and utility model patent 201120350092.8 (authorization) from R & D, using the blade axis and the spindle is not in the same plane, making the hammercan be placed inside the pitch wheel, easy miniaturization and sealing.

该变桨轮毂以其体积小、不需电控的离心机械变桨方案，达到了极好的调控精度，同时，可使得风力发电机在起动风速以上具有稳定的转速和电压，可保证其发电能力不受风暴影响，在13级以上的强风中还能实现正常发电而不需停车，可有效提高风能利用效率。

The pitch wheel hub for its small size, do not need to electronically controlled centrifugal mechanical pitch program to achieve an excellent accuracy of regulation, at the same time, can make the wind turbine above the starting wind speed with a stable speed and voltage, can ensure that its power generationcapacity is not a crisis, can achieve the normal power generation without the need for parking in the strong winds of more than 13, can effectively improve the efficiency of wind energy utilization.

2.配有变桨轮毂的并网专用风力发电机，不需并网逆变器和其它电子控制器，简单可靠价格低，特别适用许可小型机并网的地区。

2 for grid-connected wind turbine variable paddle wheels, without grid-connected inverter and other electronic controller, simple and reliable low prices, especially for the license minicomputer and network areas.

发电机采用专门技术的交流发电机，能自动同步电网频率，不需昂贵的并网逆变器，且坚固耐用寿命长。
