Wind Turbine Protection Help
Wind Turbine Protection Help
(OP)
We are putting up 2-1800kW Wind turbines and connecting them to a 12.5kV distribution feeder. I need help from anyone out there on the best way to set up fault protection on these units and on our feeder breaker. From what I have heard so far, these turbines can be considered like a large induction generator/motor.
Any tips,links,experiences would be greatly appreciated.
Thanks.

RE: Wind Turbine Protection Help
There are two facets to equipment protection. An agreement between the independent power producer and wheeling utility will cover the utilities’ concern is that the connected equipment will not affect the safety and stability of their system, but in some cases interconnection and generating equipment protection are not the same.
In the US, utilities and Public Utilities Commissions often publish web-accessible descriptions of minimum protective schemes. Induction machines are typically easier to protect than equivalently sized synchronous machines, so there will be protective elements for IPP-domain equipment that will be of no concern to the wheeling utility. One example is www.pge.com/customer_services/business/tariffs/pdf/ER21...

Just a short list of possible solutions:
-induction generator
-induction generator with AC-Controller
-induction generator with voltage sourec converter
-double fed induction machine
-synchronous generator with volatge source converter
So protecion requirements might be different from a large induction motor.

The protection system used will depend on what type of units you're using. Are they doubly fed induction generators? The manufacturer of the turbines should be able to give you the recommended protection scheme.
As for the utility, they won't be concerned about impacts on the network, since your output is only 3.6 MW. They make ask you to have a unity power factor, or at least a 0.95 p.f.
For larger wind farms the "voltage ride through capability" of the turbines becomes a major issue, because induction generators tend to trip for any voltage dips. If their output is large, the tripping can have significant adverse effects on the network.
