We had to start a large motor at a mill. Typically,we would start and synchronize the generators and then start the motor. When the motor was successfully started, we would start the other loads.
Also, at a small power plant, when going back online after an outage, if the anticipated load was more than one set could handle we would start and sync two sets prior to picking up the load.
If there is any variation of the governors at no load, you will have reverse power. If the load will be applied within a few minutes, it may be safe to bypass the reverse power protection until some load is added.
Reverse power damage usually takes some time to develop.
What type of prime movers do you have.
