The Application of Digital Twins of the Subsystems of APCS of NPP at the Stage of Factory Tests

The task of executing factory tests of the subsystems, including in the Automated process control system (APCS) of a Nuclear power plant (NPP), in the absence of actual related subsystems, is considered. The methods for solving this problem using software and hardware modeling tools (digital twins) for the subsystems of upper and lower levels of APCS of NPP are proposed.
