Hi Waross, I do not have the details of these inertial storage devices. However, the client has told me they are vertical, with the mass storage below the motor/generator on a vertical axis. I have concluded that they would only be useful in, as you say, paralleling back into the grid. It...

Thanks for the responses. Have been out this morning. This system is hypothetical at this time. The client (a casino) presently uses the three backup generators to feed load at the 480V level, in the event of a loss of utility service to the ring bus. They are considering feeding the MV ring...

Largest motor is 100 HP. Running system load will be 6MW's.

In modeling a system with three 2MW diesel generators, feeding a 21KV ring bus through a step up transformer, and thus serving loads off the ring bus through step down transformers--how should the generators and their exciters be sized in relation to load? The inrush to the transformers can be...
