Function design and application exploration of intelligent DCS for coal-fired power plants
This paper analyzes the structure concept of intelligent distributed control system(DCS) in coal-fired power plant and carries out preliminary functional design according to the actual needs of power plants. Moreover
it explores the application of intelligent DCS. By using intelligence algorithm
big data technology
machine learning
expert knowledge map
multiple-object optimizing and automatic optimization
the DCS has been turned into intelligent DCS in coal-fired power plants. By the case study of intelligent DCS phased construction in Suqian Power Generation Co.
Ltd.
the intelligent DCS can realize the advanced functions such as(automatic plant startup and shutdown) APS
fault diagnosis
early warning
automatic optimization processing
operation control
optimization and operational guidance
and this greatly improves the safety and stability of thermal power plants in a long running period
reduces energy consumption of power generation
improves the clean level of power generation process
and improves the economic benefit of thermal power generation.
