微风兆瓦级风力发电场成果

风力发电场系统研发生产介绍

概述 以前用于风电场的风力发电机都是1MW以上的特大型风力发电机，这种风力发电机的地面高度一百多米，风叶长度九十多米，要使这个大风叶转动起来，需要强大的风力才可以。一般需要风速4米/秒以上才能够使风叶转动，风速5米/秒以上才能并网发电，且并网发电只有10%的设计功率。要想得到发电量达80%的设计功率，风速最少在10米/秒。

由于世界多年来的风沙治理，大面积的植树造林，地球环境日益改善，使得风速越来越小。即使在著名的世界级“风库”，全年风速5米/秒以上也不足1000小时。内地就更无从谈起大型风力发电了。

我们单位研究开发了一款用“多台小型微风风力发电机并机组成大功率发电系统”方案，克服了以上的缺点。研究成果表明：3米/秒完全可以发电并网，4米/秒风速并网功率在设计功率的32%。7米/秒风速能够足功率发电。3米/秒以上的风速普遍存在于世界各个角落。如中国1/8部分地区3.5米/秒以上风速的年平均3800小时。

性价比的对比 1MW大型风力发电机现场安装十分困难，因为风力发电场都是在废弃的荒芜地带，大型安装设备进入困难，安全风险很大，耗资特大。1MW风力发电机正常运转后，最终耗资1452万元。

我们单位的方案，是选取“无磁阻微风风力发电机”，额定功率1000W，1000只这种无磁阻微风风力发电机组合就是1MW。

无磁阻微风风力发电机安装容易，风险性很小，安全可靠。维护简单容易，维护中不影响正常发电。投资费用很低，它高度不超过15米，为减少占地面积，可以高低错层安装，面积功率比是大型风力发电场的一倍。

如果是定风场，如我们在钦州市海边，因风叶不需要摆动，风力发电机密度很大，单位面积比陆地不定风向高达6倍。再配上我们专利的高效率达45%的转轮风叶（普通风叶是32%），单位面积发电量更大。

1MW最终耗资650万元。

“多台小型微风风力发电机并机组成大功率发电系统”有详细的施工方案 本方案已经在中国实施了100KW的试验。试验结果与预期设想一样。

Xuzhou send the Macao electronic institute wind farm system research and development production are introduced

An overview of the Formerly used for wind turbines are above 1MW wind turbine of oversized, the height of the wind turbine is over one hundred meters, the wind blade length ninety meters, to make the wind blade turn up, need a strong wind. Generally need to wind speed more than 4 m/s will be able to make the blades rotating, more than 5 m/s wind speed can be connected to the grid, and power grid power only 10% of the design. To get the design power of the power output by 80%, wind speed at least 10 m/s.

Due to the sand management the world over the years, a large area of afforestation and improving the earth environment, makes the wind speed is more and more small. Even in the famous world class library of "wind", the year more than 5 m/s wind speed is less than 1000 hours. The mainland is more impossible large wind power generation.

We use unit research developed an "many sets of small wind turbines weaver of high-power power systems", overcome the above shortcomings. Research results show that the 3 m/s can completely, grid-connected power grid power 4 m/s wind speed in the design of 32%. 7 m/s wind speed can sufficient power to produce electricity. More than 3 m/s wind speed are widespread in every corner. Such as China 1/8 parts of more than 3.5 m/s wind speed of annual average 3800 hours.

The contrast of price 1MW large wind generator field under the very difficult, because the wind farms are abandoned wilderness, large installation equipment into difficulties, safety risk is very big, heavy cost. After the 1MW wind turbine operation, the final cost 14.52 million yuan.

Our unit, is to choose "no reluctance wind turbines", rated power of 1000W, 1000 of the no reluctance breeze combination is 1MW.

Easy to install, no reluctance wind turbines risk is small, safe and reliable. Easy maintenance, maintenance will not affect the normal power. Investment cost is low, it is no more than 15 meters high, in order to reduce cover an area of an area, can be installed wrong layer, the area power ratio is twice as large wind farms.

1MW eventually cost 6.5 million yuan.

Many sets of small wind turbines weaver composition scheme of high power generating system This scheme has implemented a small test in China. The test results as expected.

This plan China patent no. 2010201204963 (query)
