Claim 21:
22. A non-transitory computer-readable medium storing instructions executable by one or more computers to perform operations comprising:
in an industrial plant implementing steam and power systems, the industrial plant comprising a plurality of equipment comprising a cogeneration system and a steam turbine:
for each equipment of the plurality of equipment:
receiving, by a computer system and during operation of each equipment, measured operational physical parameter values output by the equipment during the operation of the equipment,
determining, by the computer system, and using the received operational physical parameter values, mass balance and energy balance parameters associated with the equipment, and
validating, by the computer system, an operation of the equipment using the determined mass balance and energy balance parameters; and

after validating mass balance and energy balance parameters for the plurality of equipment:
determining, by the computer system and using determined mass balance and energy balance parameters for each equipment of the plurality of equipment, mass balance and energy balance parameters associated with the industrial plant, and
validating, by the computer system, an operation of the industrial plant using the determined mass balance and energy balance parameters associated with the industrial plant,

wherein, for each equipment of the plurality of equipment, validating the operation of the equipment using the determined mass balance and energy balance parameters is implemented as a level in a multi-level validation process, wherein the multi-level validation process further comprises verifying that each measured operational physical parameter value output by the equipment during the operation of the equipment is within a threshold physical parameter value range associated with the equipment,
wherein the multi-level validation process further comprises comparing each measured operational physical parameter value output by the equipment during the operation of the equipment with stored historical data comprising historically measured operational physical parameter values output during past operations of the equipment,
wherein the multi-level validation process further comprises, based on a result of verifying that each measured operational physical parameter value output by the equipment during the operation of the equipment is within the threshold physical parameter value range associated with the equipment, and based on comparing each measured operational physical parameter value output by the equipment during the operation of the equipment with stored historical data comprising historically measured operational physical parameter values output during past operations of the equipment, classifying each measured operational physical parameter value as a value that accurately represents an operational state of the equipment or as a value that comparatively less accurately represents the operational state of the equipment,
wherein validating the operation of the industrial plant using the determined mass balance and energy balance parameters associated with the industrial plant comprises:
determining, using the mass balance and energy balance parameters associated with the industrial plant, that the industrial plant is operating outside threshold parameters associated with the industrial plant;
in response to determining that the industrial plant is operating outside the threshold parameters, determining a level to which a physical process input to one or more of the equipment of the plurality of equipment is to be modified to cause the industrial plant to operate within the threshold parameters; and
transmitting instructions to cause an operation of the physical process to be modified to the determined level, and

wherein the physical process is flow of steam to one or more of the equipment of the plurality of equipment, wherein the level to which the physical process is to be modified comprises a change in a flow rate at which the steam is flowed to the one or more of the equipment of the plurality of equipment.
