从而极大提升火力发电机组长周期安全稳定运行的能力

降低发电能耗

提高发电过程的清洁水平

提高火力发电的经济效益。

Abstract

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.
