PROCESS INFORMATION SYSTEM (UNIT’S UPPER LEVEL)

The IVS process information system of a unit’s upper level is one of the main components of an I&C system of NPP units.

Functions of IVS:

• providing information to personnel in an operating circuit of a main control room and local control stations;
• registering and documenting technological process parameters in all modes of operation of a unit;
• monitoring critical safety functions;
• monitoring basic safety parameters;
• providing recommendations as to equipment control in transient modes of operation of a unit;
• calculating and analyzing technical and economical parameters of unit’s equipment;
• providing reference information about technological equipment and facilities of a unit’s I&C system;
• calibrating measuring channels metrologically.

Composition of IVS:

• the lower level is implemented based on MSKU-4 failsafe industrial controllers;
• the upper level is implemented based on PS5140 industrial workstations.

System advantages:

• possibility of step-by-step modernization of operating IVS systems with preservation of designed functions;
• built-in functions of a safety parameters display subsystem;
• implementation of unified protocols of data exchange with adjacent systems;
• wide list of additional functions, adaptation of control ergonomics to meet preferences of operating personnel;
• high degree of approbation of technical solutions due to a long-term experience of operation at NPP units;
• availability of built-in automated means for calibration of measuring channels.

Safety class – 3.
