Abstract

A method and system for operating a facility having a plurality of equipment combinations wherein each equipment combination is operating interactively with at least one of another of the plurality of equipment combination is provided. The method includes receiving, in real-time, for each of the plurality of equipment combinations, a plurality of measured process parameters, determining at least one derived quantity from the plurality of measured process parameters, and recommending a change to an equipment operation based on the measured process parameters and the derived quantities.

Claims

1. An integrated monitoring and control system for a plant including a plurality of equipment combinations that each include a driver machine and a driven machine coupled in rotational synchronicity, wherein each of the plurality of equipment combinations are operable interactively with each other and with individual equipment and wherein each of the plurality of equipment combinations are operable to maintain selected plant operational conditions, said monitoring and control system comprising:

a plurality of sensors operatively coupled to each of the plurality of equipment combinations, the plurality of sensors measuring process parameters for monitoring plant operation and assessing equipment combination conditions, and providing output signals to at least one component of said monitoring and control system;

a derived quantity layer communicatively coupled to a data bus, said derived quantity layer configured to;

receive the measured process parameters;

compute values for process parameters using the measured process parameters; and

compare a first measured process parameter associated with a first of the plurality of equipment combinations to a first computed value based on a second measured process parameter associated with a second of the plurality of equipment combinations;

a rule set layer comprising at least one rule associated with each of the plurality of equipment combinations for determining a health of each of the equipment combinations; and

a recommendation layer for correlating the health of each of the equipment combination to at least one of a mitigating procedure, a maintaining procedure, and an operation procedure.

2. An integrated monitoring and control system for a plant in accordance with claim 1 further comprising a communications layer for sampling said sensor output signals communicatively coupled to the output signals.

3. An integrated monitoring and control system for a plant in accordance with claim 2 wherein said communications layer is configured to receive network message packets of sensor output data.

4. An integrated monitoring and control system for a plant in accordance with claim 2 wherein said communications layer is configured to preprocess said sensor output signals.

5. An integrated monitoring and control system for a plant in accordance with claim 1 further comprising a display layer configured to generate graphical representations of measured process parameters and derived quantities.

6. An integrated monitoring and control system for a plant in accordance with claim 5 wherein said display layer is configured to generate graphical representations of measured process parameters and derived quantities in at least one of real-time, historical values, and a combination of real-time and historical values.

7. An integrated monitoring and control system for a plant in accordance with claim 1 wherein said mitigating procedure includes selectable control actions that are determined from a rule for at least one of facilitating reducing damage to equipment from an equipment failure, and maintaining the plant in an overall operational condition.

8. An integrated monitoring and control system for a plant in accordance with claim 1 wherein said maintenance procedure includes maintenance actions that are determined from a rule for at least one of facilitating reducing an equipment outage time, increasing an equipment combination availability, and facilitating reducing equipment combination failure.
