Wind Power

As with all such questions, it depends (on the purpose of the studies, and the type of wind generator). What is modeled should be what is there. Induction generator turbines should use an induction motor model with negative real power (so that their fault current contribution, and reactive demand increase when (re) accelerating are captured). 100% inverted turbines are usually represented as a static P (possibly Q) load. Double fed turbines...may require careful thought. Obviously, dispatch/s ...

The wind speed should be mainly from 5 to 20 m/sec because this range permits the wind turbine to operation. Outside this interval, the wind turbine does not operate. It is also necessary to have historical data relevant to the wind speed for 20 years back. These data are available in certain meteorological web site or you can find measures of a site close to the airport and doing approximations to have suitable values corresponding to the site where it is proposed to install the wind farm. < ...

Energy storage will be playing an important role for the next years to come. Lots of companies are involve in the research and development of new type of battery cell designs to be used in new compensation systems technologies, like statcoms, while other relay in the use of flywheels in order to face the challenges that the new generation will be demanding.

The world is moving toward the ...

We have a 2 by 275kW wind power generators connected to a system with two generators one giving a maximum of 500kW and the other 180kW both having speeds of 750 rpm. All these are to supply a load of about 470kW normal hour and a peak load of about 650kW. The problem is one diesel generator (500kW in this case) is not able to be supply load when interconnected with the wind turbines due high frequency swings (47Hz to 53Hz and the diesel gen-set finally falling off) to reduce this effect we ar ...
