DCS features strong versatility, flexible system configuration, comprehensive control functions, easy data processing, centralized display and operation, a user-friendly interface, simple and standardized installation, convenient debugging, and safe and reliable operation, and is currently widely used. Especially in power plants, not only are new units equipped with DCS systems, but some older units also have their original, outdated control, protection, and regulation methods upgraded to distributed control systems. Modern large-scale power units no longer rely solely on functions such as on-site data acquisition and monitoring (DAS) and analog control (MCS); 300MW units come equipped with functions like FSSS, CCS, and SCS ； Moreover, other functions of some units such as DEH, MEH, and ETS are also incorporated into the DCS.
DCS Reliability: 1. Redundancy requirements – Redundancy is required for DCS I/O cards, controllers, power supply modules, communication modules, etc； 2. Hardware quality requirements: the metric is mean time between failures (MTBF). 3. Interference resistance. 4. System scalability. 5. Maturity of system software
