NCS: Power network computer monitoring system (NCS for short), usually used in plant transformer systems;
ECS: Power plant electrical monitoring and management system (Electric Control System), usually used in units;
DCS: Also known as distributed control system, it controls various execution components according to the operation logic of the power plant based on various simulation data volumes and the logic of the power plant operation. This is a comprehensive system. The basic functions of light can accurately collect various data and correctly issue control instructions. The key is the analysis and judgment of various data. It is usually used in booster stations.
Extended information:
It is a multi-level computer system composed of process control level and process monitoring level with communication network as the link. It integrates 4C technologies such as computer, communication, display and control. Its basic idea is decentralized control, centralized operation, hierarchical management, flexible configuration and convenient configuration.
In special control fields, such as nuclear power plant control systems, the meaning of DCS is mistakenly called digital control system (Digital control system), but its essence is still a distributed operating system.
