Trustworthy Paralleling Electrical Generators

Is this to be used on a gridd as a back-up during main feed black outs?

Or, is this to be a primary remote feed to a gridd?

Mr. Maximo:

Primary remote site generators by now.

Long term backup generators.

Dear SERCA,

That is expensive plant you are going to install.

I have past smaller experience and suggest this way:

4 N0s. 500KW DFEK: Parallel onto a BUS #1 and keep locked to share load equally.And maintain fixed RPM and Output Volts.(Current will be determined by SYSTEM.)

You can do this if you buy /install/use:

• Parallel Load Transfer equipment
• Digital Paralleling Switchgear
• PowerCommand network and switchgear - ALL kept on Auto

*****************************

6 Nos 300KVA ESP:Parallel 2 nos each to Bus#2,3,4.

Each pair on Bus #2,3,4 shall be shut down Manually .

When loads pick up and main bus shows overloading, you will get warning to add 2 more 300KVA sets onto Bus#1 after restarting/steadying/pair-paralleling . But you should be able to feed special loads directly.

Set all 6 to 90% rated load(future>95%,>100%.!05% all possible)

**********************************

Above means enable you to cut in/ out pairs of 300KVA's after judging overall loads.

500KW'S will float up or down to deliver efficiently generated power close to max.efficiency.

All depends on load pattern over 24x7 day basis.

Also from Cummins you can buy fully Automatic Cut-in/out controls for all 10 Gensets to achieve above MODE of Cut-off and Cut- in.

I feel the operator will go to sleep if you do that. Better to give him a decision making.

Thanks Mr. Mukulmahant.

Everything is so simple these days. We used a synchroscope with the needle going slow in the fast direction to synchronize an oncoming AC generator when paralleling in my Navy days.
