سلام
بنده باید ایمیلی بفرستم به یک شرکت خارجی. نامه را آماده کردم، شما فقط زحمت بکشید یه چک بکنید ببینید اشکال خاصی نداشته باشه.
Dear Sir,
I am a member of a group of engineers undertaking to install two 2 KW wind turbines in a farm which is located in Isfahan-Iran. I have a few questions.
We installed one of the towers (including generator, blades and tail) yesterday but unfortunately we didn't feel it to be in steady state so we have stopped the blades rotating by fastening one of the blades by a rope. first of all we should make sure that the blades would not rotating. Then we would make the tower stronger in order to reduce the vibration of the tower (it would be done by professionals). Then we would improve the wire rope by dividing it into 4 septate parts- as it is in two parts now and can't hold the tower firmly and in steady state. So I would be thankful if you tell me any other secure way to stop the blades turning and I'm sure that your suggestions and tips would be helpful.
I've attached a photo of the mentioned turbine and the total diagram. Do you verify the diagram of installation?
and the last question is, how can we make sure that the blades speed would not exceed that maximum allowable speed?
Thank you for taking the time to read this Email.
Respectfully
My name
Azad University of Isfahan-Khorasgan
