Duplex Reactor Coupled Generator

[GerH]

I read an embedded generator can be connected in parallel with utility using a duplex reactor to isolate the site load from grid faults. Embedded generator is running continuously ( Heat & power plant).

Can anyone advise how to design this reactor or recommend an expert with experience. Our application is 20kV, 5MW.

The GE Industrial Power Systems Data Book (1950's) covered the application of a Duplex-Reactor as a means for reducing short-circuit duty, in great detail!

Thanks. Any idea where I could get a copy of this?

The reactor is simply sized to limit the fault current from the utility connection to a value that the site equipment ratings can handle. Run a Short Circuit Study using the utility contribution to determine what size reactor is necessary to limit the fault current to the value needed. Or is this why you need a consultant?

Reactor manufactures are Ritz and Trench.

In order to spec the reactor, they will need the following:

-System voltage
-reactance/inductance
-frequency
-fault current (i.e. 1 sec current) after the reactor is inserted
-rated continuous current
-mounting configuration, i.e. single-phase/three-phase stacked
-any space limitations

ScottF - can you provide the url for Ritz's website if they have one - I had not heard of them. I have used Trench current limiting reactors.
