<p>A power system specifically designed to provide reliable electrical power to a telecommunication facility is disclosed. The system includes a number of microturbine generators adapted to provide AC power that is then rectified to DC power by an array o f rectifiers. The system is configured so that the microturbine generators are fueled initially by utility-supplied natural gas. In the event the utility-supplied natural gas fails, the system provides propane from a storage tank to fuel the microturbine generators. If both microturbine generator fuel sources fail or their fuel supply becomes exhausted, power is supplied to the rectifiers by a commercia l electrical utility. The system also includes a number of hydrogen-powered proton exchange membranes that are operable to supply DC power directly to the facility if both the microturbine generators and the electrical utility fail. Finally, a number of super capacitors are coupled to the bus line directly connected to the facility in order to maintain power if it becomes necessary to switch power sources.</p> |
