A system for monitoring a power system and controlling an operation is provided. The system includes: a process setting unit receiving a process modeling file from a user and setting, as a process setting model, a process modeling file on which process verification is completed; a process verification unit performing the verification of preset process modeling items on the process modeling files received from the user; and a data storage unit storing file information for the operation of a system, the process modeling file, process modeling verification results, and the process setting file.

A field device, which measures a physical quantity in a plant or processes the physical quantity, includes: an instruction unit configured to output a verification execution instruction signal for instructing execution of verification of the field device; an operation verifying unit configured to verify an operation of at least one element of the field device in response to the verification execution instruction signal and to verify an operation of the field device based on the verification result; and an output unit configured to output the verification result which is a result of verification of the operation by the operation verifying unit.

A method for verifying process orchestration logic for a modular plant includes generating a plant execution model representing the process orchestration logic; analyzing the plant execution model to identify one or more potential failure scenarios; and generating one or more test cases based on the one or more identified failure scenarios.
