The nomadic herdsmen erect their yurts in places with abundant water and grass and install a wind - driven generator . they plan to stay there for some time 游動的牧民來到水草豐茂的地方扎下氈包,豎起風力發(fā)電機,準備在這里放牧一段時間。
Regarding of the complexity and reliability of the wind - driven generating system , most parts of the powerful wind - driven generators in home can just depend on import , which justifiably makes the cost of the wind - driven generating pretty high . so it ’ s urgently to carry out the research of the speeding device in the wind - driven generating system to make this way of generating electric more economic 但是由于風力發(fā)電系統(tǒng)結構復雜、可靠性要求高,目前國內大功率的風力發(fā)電機組中眾多部件都是從國外進口,使得風力發(fā)電成本居高不下,因此急需自主開發(fā)研究大功率的風力發(fā)電增速裝置系統(tǒng)使得風力發(fā)電更加系統(tǒng)化和經濟化。
Do the roughly introduction to the wind - driven generator through the way in which the wind - driven generator classifies ; introduce the structure and principle of fd26 - 250kw wind - driven generator , probe into the method of calculating the power of wind - driven generator when the wind is in the low speed , and analyse the course of incorporating the power of fd26 - 250kw wind - driven generator into electricity net ; study on how to supervise the state of the wind - driven generator and diagnose it ’ s malfunction , then confirm the way to build the system of fault diagnosing 2 .對風能利用的主要設備風力發(fā)電機進行了研究。著重介紹風力發(fā)電機fd26 - 250kw的結構及原理,探討風力發(fā)電機低風速功率的計算方法,并分析了風力發(fā)電機的并網過程;提出并實現了風力發(fā)電機狀態(tài)監(jiān)測與故障診斷方法。 3 .對如何最優(yōu)分配太陽能和風能設備的投入這一關鍵問題進行研究。
