Technical Issues in Wind Turbine
Technical Issues in Wind Turbine
(OP)
Hello people..There are few issues that i do not understand when i was reading to the GE catalogue which is shown below.
There are few technologies they develop that i find it hard to understand coz i m a newbie and don't really have a good engineering foundation for me to understand this..Hopefully you guys who are more experienced can help...Firstly in the webpage., it stated-
http:// www.gepowe r.com/prod _serv/prod ucts/wind_ turbines/e n/15mw/tec h_data.htm
1)'The energy of a gust is stored by accelerating the rotor. This leads to reduced loads, improved transmission efficiencies and performance.'
How can this be done or actually how does it work ? i mean the energy storage.
2)Reactive Power Control
Does this mean that this will improve the Power Factor ? Correct me if i am wrong...
3) And finally from this webpage http://ww w.gepower. com/prod_s erv/produc ts/wind_tu rbines/en/ downloads/ wind_plant _perf2.pdf
it says that reactive power can still be generate even though there is no wind...is this possible ? but how ?
Hopefully you all are able to give some clues or hints..Hope to hear from you soon.. Thanks in advance and have a good day ahead :)

RE: Technical Issues in Wind Turbine
GE uses a doubly-fed induction generator in their wind turbines. The back-to-back converter used in this control system allows control of power factor (reactive power). That is the basis for all of this marketing hyperbole.
I'd suggest taking a long look at the doubly-fed generator technology they are using. That will give you a better understanding of what is going on.
