Mixing Wind Turbine in Wind Farms
Mixing Wind Turbine in Wind Farms
(OP)
Hello there,
Is there any problems to have different manufacturers (etc Vestas combined with GE wind turbines) of wind turbine in a same wind farms ? Will this effect much of the power generation ? Hope someone will be kind enough to clarify this. Thanks alot in advanced.

From maintenance and service point of view, having the same manufacturer makes more sense. It also builds a relationship one vendor which goes a long way resolving issues.
I do not pretend to be a wind turbine expert, just expressing views based on what I know.

It is no different than mixing two regular synchronous gens of different manufactuers, which is technically doable but could pose problems because of some controls issues.
In theory, any two induction machines should be able to connect to a common grid. I am assuming these are induction machines.
I would even say, as long as each collector bus in a wind farm has machines of the same manufacturer it should work, even if other collector bus has different make of machines.
Again, this is just my opinion based on what I have leaned of WTGs, by reading literature. I am no expert in WTG but electrically they are simple machines. In fact I would be involved with my first WTG interconnection project soon- 2-2MW units.
From a businessman and/or a professional point of view, I would try to stay away from troubles and not be too enthusiastic about mixing two different mfrs on a project. Besides potential technical issues, it is just a bad business and PR issue.

In practice, there is not enough difference to be a problem.

I agree with Scotty though, they are likely (particularly the brands suggested) to be different technologies, and as such may behave differently under certain conditions. This may include minimum wind speed to produce power, speed of reaction (i.e. shutdown or feathering of blades) when a wind overspeed event occurs, and ability to regulate the output of the turbine in wind conditions.
Its obviously impossible to predict what issues may arise without knowing what the technologies involved are, and this just adds to the benefit of sticking to one manufacturer. Are multiples being considered due to the lead time for turbines?

No problems. If you have any doubts about a particular machine, you should talk to the OEM. As a supplier, they would have studied your farm and would be able to answer your questions.
