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.
