A DCS is a decentralized control system architecture used for large-scale industrial automation and process management.
Distributed Control System (DCS) is implemented in large manufacturing plants, integrating numerous process controllers connected by a network. This architecture allows for increased reliability, scalability, and efficient management of complex industrial processes. DCSs are essential in industries such as oil refining, power generation, and chemical processing, where control precision and adaptability are crucial.
A DCS manages an oil refinery's complex processes across various units, including the catalytic cracker unit and distillation unit, with precise temperature control maintained within a range of ±1°C (±1.8°F).
Commonly employed in the petrochemical industry for complex process control and safety automation.
In a power generation facility, a DCS optimizes turbine generator outputs by controlling steam pressure within ±0.5 MPa (±72.5 psi), enhancing energy efficiency and maintaining operational safety.
Used in both fossil fuel and nuclear power plants to enhance system responsiveness and safety.
