Abstract
A backup power system and method of use is provided for powering at least one load wherein the at least one load is normally connected to grid power at a grid frequency. The system and method include providing a generator powered by a fuel in gas phase, such as natural gas; detecting loss of grid power to the at least one load; driving the generator to an operating frequency equal to a predetermined driven frequency that is greater than the grid frequency; and selectively coupling the at least one load to the generator via a load controller while the generator is at the predetermined driven frequency.
Claims23
A backup power system for providing power to at least one load, the at least one load being normally connected to grid power at a grid frequency, the backup power system comprising:
- a generator powered by a fuel in gas phase;
- a power controller operably coupled to the generator, the power controller configured to control an operating frequency of the generator;
- and
- the power controller configured to be coupled to the at least one load,
- wherein the power controller is configured to output a generator control signal to the generator upon loss of the grid power to change an operating frequency of the generator to a predetermined driven frequency greater than the grid frequency, and
- wherein the power controller is configured to selectively couple the at least one load to the generator at the predetermined driven frequency.
A method of providing a backup power system providing power to at least one load, the at least one load being normally connected to grid power at a grid frequency, the method comprising:
- providing a generator powered by a fuel in gas phase;
- detecting loss of grid power to the at least one load;
- the driving the generator to an operating frequency equal to a predetermined driven frequency, the predetermined driven frequency being greater than the grid frequency;
- and
- selectively coupling the at least one load to the generator via a power controller while the generator is at the predetermined driven frequency.
