T/SZBX 189-2024 Nationwide localization of distributed control system for thermal power plant maintenance procedures
Basic Information
Scope
This standard specifies the minimum requirements for the maintenance of domestically-produced DCS systems in thermal power plants, including pre-shutdown inspections, post-shutdown maintenance, the maintenance of main controllers and functional modules, the maintenance of workstation (computer) hardware, the maintenance of power supply equipment, the maintenance of computer peripherals, the maintenance of network and interface equipment, the maintenance of cabinet fans and cooling fan assemblies, the maintenance of master clocks and GPS standard clock devices, and software inspections. This standard applies to the commissioning of domestically-produced DCS systems in newly built, expanded, or modified power stations, such as coal-fired power plants, gas-fired power plants, biomass power plants, and waste incineration power plants.
