Problems solved by technology

Geographically remote areas such as islands or mountainous regions are often not connected to main utility electrical grids due to the cost of installing and maintaining the necessary transmission lines to carry the electricity.
Even in remote communities where the transmission lines are in place, it is not uncommon for frequent and extended power outages due to weather related faults.
In either case, to prevent economic loss in times of an electrical outage, it is often necessary for these communities or industries in these regions to create local “micro” electrical grids to ensure a reliable and uninterruptible power system.
This uninterruptible power system may be either a primary system where there is no connection to the main utility grid, or a backup system that activates when an outage occurs.

Embodiment Construction

[0028] The following description will provide specific examples with respect to the load and power source voltages for example only. It will also be understood that the method and apparatus for bridging short duration power interruptions may be used with different types of primary / secondary sources and / or other operating voltages, and is not limited to the implementations described herein. Various power sources can range from grid power to solar power, hydroelectric power, tidal power, wind power, fuel cell power, and the like, as well as combinations comprising at least one of the foregoing power sources (e.g., via solar panel(s), wind mill(s), dams with turbines, electrochemical cell systems, and the like).

[0029]FIG. 1 depicts a block diagram of a portion of power system 10 having a primary power source 32 such as generated grid power or that from a renewable source, a secondary power source 100 and a load 36, which load 36 is fed from a feeder bus 38. In the example shown, the p...

Abstract

A system for providing back-up power to a load powered by a primary power source comprises: a fuel cell arrangement for generating back-up power for the load, a bridging power source for generating bridge power for the load, and a controller in operable communication with the fuel cell arrangement and the bridging power source. The controller is adapted to initiate application of the bridge power to the load upon detecting a deterioration of power from the primary power source, and is further adapted to initiate application of the back-up power to the load upon detecting a power capability of the back-up power to power the load.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation application of U.S. patent application Ser. No. 10 / 065,387 filed Oct. 11, 2002, which claims the benefit of U.S. Provisional Application No. 60 / 328,996, filed Oct. 12, 2001 and U.S. Provisional Application No. 60 / 410,412, filed Sep. 13, 2002; the contents of all of which are incorporated by reference herein in their entirety.BACKGROUND OF INVENTION [0002] This disclosure relates generally to power systems, and especially relates to the storage and recovery of energy from a renewable power source and electrochemical cells. [0003] Geographically remote areas such as islands or mountainous regions are often not connected to main utility electrical grids due to the cost of installing and maintaining the necessary transmission lines to carry the electricity. Even in remote communities where the transmission lines are in place, it is not uncommon for frequent and extended power outages due to weather related...
