Abstract

The invention discloses a distributed control system (DCS) frame for a nuclear power reactor. The frame includes a safety-level DCS and a non-safety-level DCS; the non-safety-level DCS includes a non-safety-level monitoring device, a monitoring network, a non-safety-level gateway, a real-time server, a system network, a first control station, a diversified drive system and the like on an operationstation, wherein the non-safety-level monitoring device, the monitoring network, the real-time server, the system network and the first control station are connected in sequence; and the safety-levelDCS includes a plurality of protection groups, a specially-arranged safety facility drive cabinet, a data transmission cabinet, a safety-level bus, a safety-level gateway, a device interface cabinet,a safety-level monitoring device on a backup disk and the like, wherein the safety-level bus, the safety-level gateway, the non-safety-level gateway and the monitoring network are connected in sequence. By implementing the frame, a compact layout scheme of a main control room can be constructed on the premise of ensuring the basic functions of the main control room.

Description

technical field

[0001] The invention relates to the technical field of nuclear power plants, in particular to a nuclear power reactor DCS architecture. Background technique

[0002] Digital Distributed Control System (DCS, Distributed Control System) is a comprehensive control system that emerged with the continuous rise of modern large-scale industrial production automation and the increasingly complex requirements of process control. Modern equipment for management and improvement of nuclear power plant operation safety, reliability and management efficiency. At present, the main control room architecture scheme of digital nuclear power based on DCS can refer to the main control room architecture scheme of land commercial nuclear power plants, such as figure 1 As shown, it is divided into two parts, a safety-level DCS and a non-safety-level DCS, which are implemented on different platforms. The security-level DCS mainly completes the monitoring of security-level equipmen...
