A method and apparatus for operating a power system is disclosed. A plurality of sensor signals each representative of an operating characteristic of a power system module are received at a common data bus. The sensor signals are received and analyzed at a controller for the presence of an abnormal operating condition, and in response thereto it is determined whether an operational adjustment of the power system module is desirable. In response to the existence of a desirable adjustment condition, the operation of the power system module is automatically adjusted. A sensor of the plurality of sensors is arranged for providing an operating characteristic that is derivable from one or more of the other sensors, which include a different type of sensor, thereby providing redundant system information for determining whether an operational adjustment of the power system module is desirable.

The invention claimed is: 1. A method for operating a power system, comprising: receiving a plurality of sensor signals at common data bus, each sensor signal representative of an operating characteristic of a power system module; receiving and analyzing at a controller the sensor signals from the common data bus for the presence of an abnormal operating condition, and in response thereto determining whether an operational adjustment of the power system module is desirable; and in response to the existence of a desirable adjustment condition, automatically adjusting operation of the power system module; wherein a first sensor of the plurality of sensors is arranged for providing an operating characteristic that is monitored by the first sensor and that is derivable from one or more of the other sensors, the one or more other sensors including a different type of sensor than the first sensor, thereby providing redundant system information for determining whether an operational adjustment of the power system module is desirable. 2. The method of claim 1, further comprising: providing to the common data bus an additional sensor signal representative of an operating characteristic of the power system, which results from an operating characteristic at one or more of the power system module. 3. The method of claim 1, wherein the common data bus includes a simplex channel, a redundant channel, or any combination thereof, arranged for parallel signal communication. 4. The method of claim 1, wherein the analyzing further comprises: determining whether a sensor reports an abnormal operating condition; in response to a sensed abnormal operating condition, determining whether the sensor is unhealthy; in response to the presence of an unhealthy sensor, determining whether the operating characteristic sensed by the unhealthy sensor is derivable from one or more other sensors in the power system; in response to the operating characteristic sensed by the unhealthy sensor not being derivable, determining whether an operational adjustment of the power system module is desirable; and in response to a desirable adjustment condition, automatically adjusting operation of the power system module. 5. The method of claim 4, further comprising: in response to the operating charactaistic sensed by the unhealthy sensor being derivable but the derived characteristic being indicative of an abnormal operating condition, determining whether an operational adjustment of the power system module is desirable. 6. The method of claim 5, wherein automatically adjusting the power system module comprises: changing an operating state of a valve, a pump, a switch, or an output device. 7. The method of claim 6, wherein said changing the operating state comprises: shutting down the power system module. 8. The method of claim 6, wherein said changing the operating state comprises: running the power system at reduced performance to accommodate the desirable adjustment condition. 9. The method of claim 1, further comprising: monitoring the sensor signals at the common data bus; and in response to an abnormal operating condition, automatically adjusting an operating state of a control device, in a direction to compensate for the abnormal operating condition. 10. The method of claim 1, further comprising: storing data relating to an operating characteristic of the power system module; and reporting the stored data to an external system or user on demand. 11. The method of claim 10, further comprising: processing at least a portion of the stored data to synthesize a replacement signal or to command a degraded operational mode. 12. A control system for a power system, comprising: a controller having a processor for executing instructions for: monitoring sensor signals at a common data bus, the common data burn in signal communication with a plurality of sensors, each sensor signal representative of an operating characteristic of the power system; receiving and analyzing the sensor signals to determine the existence of a malfunctioning device, the malfunctioning device including a sensor, a processing element, an output device, or a control device; and automatically reconfiguring other operational devices controlled by the control system to accommodate for the malfunctioning device. 13. The system of claim 12, wherein the processor further executes instructions for communicating over multiple channels. 14. The system of claim 13, wherein the processor further executes instructions for: receiving and analyzing the sensor signals to determine the existence of an unhealthy sensor signal; and substituting a redundant sensor signal or a derived sensor signal for the unhealthy sensor signal. 15. The system of claim 14, wherein the automatically reconfiguring comprises: adjusting an operating state of a control device, substituting a redundant sensor signal or a derived sensor signal for the unhealthy sensor signal, shutting down a power system module, or running the power system in a degraded mode. 16. The system of claim 12, wherein the processor further executes instructions for: analyzing the sensor signals for the presence of an abnormal operating condition and in response thereto, adjusting an operating state of a control device in a direction to compensate for the abnormal operating condition. 17. The system of claim 12, wherein the processor further executes instructions for: storing data relating to an operating characteristic of the power system; and reporting the stored data to an external system or user on demand. 18. A control system for a power system, comprising: a processor for executing instructions for: determining whether a sensor reports an abnormal operating condition; in response to a reported abnormal operating condition, determining whether the sensor is unhealthy; in response to the presence of an unhealthy sensor, determining whether the operating characteristic sensed by the unhealthy sensor is derivable from one or more other sensors in the power system, the one or more other sensors including a different type of sensor than the unhealthy sensor; in response to the operating characteristic sensed by the unhealthy sensor not being derivable, determining whether operational adjustment of the power system or a portion thereof is desirable; and in response to the existence of desirable adjustment condition, automatically adjusting the operating condition of the power system or a portion thereof. 19. The system of claim 18, further wherein the processor is for executing instructions for: in response to the operating characteristic sensed by the unhealthy sensor being derivable but the derived operating characteristic being indicative of an abnormal operating condition, determining whether an operational adjustment of the power system or a portion thereof is desirable. 20. The system of claim 19, wherein automatically adjusting the operating condition comprises: adjusting an operating state of a control device in a direction to compensate for the abnormal operating condition. 21. The system of claim 19, further comprising: a communication architecture for communicating sensor signals between elements of the power system, the communication architecture including a common data bus having a simplex channel, a redundant channel, or any combination thereof, arranged for parallel signal communication.
