• Intelligent Solutions to Achieve Automated Operations for Power Plant

  The Automatic Power Plant Startup and Shutdown System (APS) is the information control center for the automatic startup and shutdown of power plant units. It issues startup or shutdown commands to various equipment and systems according to a predefined program. The APS coordinates with the Coordinated Control System (CCS), the Modulating Control System (MCS), the Furnace Safety Supervisory System (FSSS), the Digital Electro-Hydraulic (DEH) Control System, the Sequence Control System (SCS), the Feed water Control System, the Burner Load Program Control System, and other control systems such as the Electrical Control System (ECS) and the Automatic Voltage Regulator System (AVR). As a result, the automatic startup or shutdown of the power plant unit is achieved.

• Optimize Control Systems for Fully Automated, High-Efficiency Boiler Operation

  Low automation level in boiler operations within thermal power units cause significant fluctuations in process parameters, hindering long-term stable and safe energy supply. Issues such as prolonged air-fuel imbalance during furnace combustion result in low boiler efficiency. Additionally, coupled disturbances among multiple boilers in a common header control unit make coordinated control challenging. The delayed adjustment of boiler flue gas emissions lead to exceeding emission standards or excessive consumption of environmental materials. The APC optimized control system helps customers overcome these challenges, ensuring long-term, fully automated, high-efficiency operation of boilers.
