10kV 50Hz DG sets
10kV 50Hz DG sets
(OP)
Does anyone know any suppliers of industrial DG sets (10kV 50Hz) greater than 3225kVA rating?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: 10kV 50Hz DG sets
10kV 50Hz is not a UK voltage - We are 11kV. We see 10kV on the continent (the rest of Europe). So that gives me a clue as to where you are.
Look on http://www.dieselpub.com/ click on "global sourcing guide". This will give you the engine manufacturers - but not packagers. The usually have local associations in each country.
At this kVA and voltage, you are getting outside what a genset packager will offer. Because their market is generally standby / low voltage they generally offer 1500 rpm engines (1800 rpm for 60 Hz). At this speed, the maximum engine power is around 2000kW,2500kVA. Low voltage also limits you to around this size, because of the practical limits to breaker rating and cabling practicalities.
If you go to higher power, you start to get engines at 1000 rpm. Higher cost, larger, heavier. More site work, as you generally transport the smaller units in a container. As I say to people: "This is a power station, please tell me how you will design and construct this power station".
Is your application standby or base load? If standby, you could go for two x 1600kVA gensets. Then have them at low voltage (400V?) and step up to 10kV with transformers. All snchronising etc is at low voltage, which can be easier to operate and maintain to the 10kV gear. You then have to decide what to do with the 10kV connection. If you need suggestions, please ask.
If your application is base load, then the lower operating costs of lower speed engines could be of a benerfit to you.

Application is standby generator to be installed in petrochem plant in China. Ideally like to find a manufacturer there but the best I've found so far is 3225kVA. Space is tight so ideally would like one set. It would be installed in a dedicated generator house.
There are a number of 10kV motors that need the supply hence the 10kV set.
Would like to try and simplify without 2 sets synchronising if possible?

Please check Hunday in S. Korea.
I don't have more information, but I know , them built DG power plant with 2 x 6MW DG set and 10 or 11.5kV ( is near to my city). Project was turnkey of Hunday.
Of course check Wartsila, as I know, them build DG power plant in all word and it's turnkey project.
