At this time, the integrated simulation server 200 diagnoses (or verifies) a driving operation state through an operation index provided in a monitoring diagnostic apparatus (e.g., an early warning system) 300 linked by OPC (OLE for Process Control) And confirms and manages the health of the monitoring and diagnosis apparatus 300 through various driving operations of the operator through an HMI (Human Machine Interface) apparatus connected to the two servers 100 and 200 through API (Application Programming Interface) communication. And to acquire know-how.

Here, each operator performs a driving operation through an operator control panel (OIS).

Here, the process model means modeling the operations performed by each process in each system (e.g., a boiler system, a power system, etc.) of the power plant in a kind of program unit, and the control model is used for controlling the facility or system of the power plant Which means that the action to be performed is modeled in a kind of program unit.

As described above, the integrated simulation server 200 is configured to perform a process model, a control model, and an integrated function of the lecturer's operation panel so that the process model 220 and the control model 210 can be selectively changed and adjusted. Accordingly, as shown in FIG. 2, simulators of various units can be implemented in combination.

FIG. 2 is a diagram illustrating a more specific configuration of the integrated simulation server 200 in FIG. 1. In the prior art, when the process model is firmly implemented, the overall operation of the integrated simulation server 200 ) Can implement and operate the process model 220 across the various fields of the plant (e.g., boiler system, power system, etc.). For example, if it is assumed that a plurality of modules (e.g., three change modules) are further implemented to operate the simulator in a total of eight modes, the eight modes may be switched and operated as shown in the table of FIG. 3 .

2, the integrated simulation server 200 includes a control model 210 and a process model 220, and includes a simulator linkage unit 101 for linkage with the control model 210, (DB) 102 for providing data accumulated in the HMI server 210.
