  1. Then analytical measurements of the noise were carried out on both of the turbines by means of modern acoustic apparatus and a conclusion has been found that the noise of the concentrated wind energy turbine is lower than the one of the ordinary wind energy turbine and the root of the trouble to cause noise chiefly originates from the turbine blade. besides, the result of analytical measurement also reveals that the power output both of the wind energy turbines will increase with the increase of the wind speed and unfortunately does the noise too. in order to lower the noise, a measures of noise reduction have been advanced that an active method is to develop a wind energy turbine run at a lower rating of wind speed while the passive method is to adopt a board drilled tiny holes, having established a sound technological basis for the development of a kind of wind energy turbine of low noise and high level in the world

    主要對濃縮風能型風力發電在正常運轉時,噪聲產生的理進行了理論分析研究,並與普通型風力發電的噪聲進行了對比實驗分析;利用現代聲學測試手段對兩類型進行測試與分析,得濃縮風能型風力發電產生噪聲低於普通型風力發電和葉輪是風力發電產生噪聲的主要部件的結論;通過對兩類型的噪聲、功率的測試,得隨著風速的增加,兩類風力發電功率在增加,產生的噪聲也在增加的結論;提了進一步降低濃縮風能型風力發電噪聲的措施,從主動降噪方面,研製低額定轉速的發電;從被動降噪方面,採用微穿板的降噪結構;為研究開發一種國際上低噪聲、高水平的風力發電下了良好的技術基礎。
