Duplex Reactor Coupled Generator

Duplex Reactor Coupled Generator

Duplex Reactor Coupled Generator

(OP)
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.

RE: Duplex Reactor Coupled Generator

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!

RE: Duplex Reactor Coupled Generator

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

RE: Duplex Reactor Coupled Generator

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?

RE: Duplex Reactor Coupled Generator

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

RE: Duplex Reactor Coupled Generator

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.

Their web site is www.ritzusa.com.
