Power distribution with wraparound bus

A method of controlling a generator set providing power to at least two units, the generator set comprising:

• a reserve generator;
• a reserve bus connecting respective units to the reserve generator;
• for respective units:
• a utility line;
• a unit generator;
• and
• a reserve switch that, responsive to detecting a unit load exceeding power from the utility line and the unit generator, routes power from the reserve bus;
• and
• a wraparound bus connecting respective unit generators to the reserve bus;
• and the method comprising:
• monitoring a reserve load on the reserve bus and power from the reserve generator;
• and
• responsive to detecting reserve load on the reserve bus exceeding power from the reserve generator:
• identifying a selected unit having spare capacity that exceeds power routed to a unit load of the selected unit;
• and
• selectively connecting the selected unit to the wraparound bus to supplement the power provided by the reserve generator for the reserve load.

A system for controlling a generator set providing power to at least two units, the generator set comprising:

• a reserve generator;
• a reserve bus connecting respective units to the reserve generator;
• for respective units:
• a utility line;
• a unit generator;
• and
• a reserve switch that, responsive to detecting unit load exceeding power from the utility line and the unit generator, routes power from the reserve bus;
• and
• a wraparound bus connecting respective unit generators to the reserve bus,
• the system comprising:
• a reserve load monitor that monitors a reserve load on the reserve bus and power from the reserve generator;
• and
• a wraparound bus connector that, responsive to detecting reserve load on the reserve bus exceeding power from the reserve generator:
• identifies a selected unit having spare power capacity that exceeds a unit load of the selected unit;
• and
• selectively connects the selected unit to the wraparound bus to supplement the power provided by the reserve generator for the reserve load.
