induction vs. synchro gensets
(OP)
Our company is looking at ways to power remote locations with minimal 480v power (50 to 300kw) and sell back the unused portion to the utility. Our applications require 24/7 operation with natural gas engines (casing gas) or diesel power - Anyone have some history with these systems and/or directions?






RE: induction vs. synchro gensets
I designed an installation of 2x500 kW natural gas engines for cogen service with induction generators, no known problems after 9+ years in service. The utility interconnect was also simpler with this arrangement, as there is no continued backfeed into utility side faults.
The downside of course is that there is no standby supply if the utility fails, as you need that supply for your excitation. If you absolutely must have 24/7 uninterrupted supply, then you need to go with a synchronous generator with appropriate controls & intertie protection to ride through utility outages - you will also get a boost in power quality with this arrangement, as voltage control will be tighter.
One thing to watch for with the induction option - you will probably need to install power factor correction capacitors, which should be sized so that they don't improve the no-load PF beyond 1.0 lagging. This is to avoid self-excitation of the induction generator.

Our company builds the power generation equipment you need for converting casinghead gas to electricity. We have both synchronous and induction units fueled by natural gas, casinghead gas, landfill methane, etc., and have placed these units in numerous 24/7 "oilfield" situations. We would be pleased to visit with you further about our equipment. You can call us at 505-623-3700 and/or visit our website at www.genergypower.com.
