Power system with computer-controlled fuel system
View Patent ↗Various embodiments of a fuel-control system for regulating the administration of a first fuel to a fuel consuming device are disclosed. In one aspect, the fuel-control system includes a system-controlling device adapted to consume a primary source of electrical power. The system controlling device is also adapted to consume a secondary source of electrical power, with the secondary source produced by noncombustibly consuming a second fuel.
1. A fuel-control system for regulating the administration of power to a controller, comprising:
a DC bus for distributing electrical power to various components of the fuel-control system;
a primary source of electrical power that supplies the electrical power to the DC bus;
an independent backup system that includes a secondary source of electrical power;
a controller adapted to consume the electrical power from either the primary source or the secondary source in a mutually exclusive manner;
a breaker adapted to selectively isolate the controller and the independent backup system from the DC bus according to signals from the controller,
wherein, when a voltage read from the DC bus falls below a predetermined minimum voltage level, the controller causes the breaker to interrupt power-supply capability between the DC bus and the controller, and
wherein, when the voltage read from the DC bus overcomes the predetermined minimum voltage level, the controller causes the breaker to restore connectivity between the DC bus and the controller.
2. The system of claim 1 , wherein the primary source of electrical power represents a gas turbine generator.
3. The system of claim 1 , wherein the primary source of electrical power is configured to consume a first fuel from a first fuel source, a second fuel from a second fuel source, or a combination of the first fuel and the second fuel.
4. The system of claim 3 , wherein the first fuel represents natural gas supplied from a utility, and wherein the second fuel represents natural gas stored in a tank.
5. The system of claim 1 , wherein the secondary source of electrical power represents a fuel cell.
6. The system of claim 1 , wherein the controller represents a programmable logic controller.
7. The system of claim 1 , wherein the controller represents a microprocessor.
8. The system of claim 3 , wherein the controller is used to control valves that regulate the administration of the first fuel and the second fuel to the primary source of electrical power.
9. The system of claim 8 , wherein the controller receives information from at least one pressure sensor, the at least one sensor being configured to detect a first gas pressure in a first conduit that transports the first fuel.
10. The system of claim 9 , wherein the controller receives information from at least one pressure sensor, the at least one sensor being configured to detect a second gas pressure in a second conduit that transports the second fuel.
11. The system of claim 5 , wherein the secondary source of electrical power is configured to consume hydrogen gas.
