Abstract:
Introduction Traditional distributed control system (DCS) has many problems, such as single monitoring screen, repeated alarm, and inability to support advanced algorithms. With the development of digital technology, various manufacturers have developed new intelligent control systems. Through the analysis of the scheme of application of the intelligent control system to a 1 000 MW ultra-supercritical secondary reheating unit, this paper provides effective reference for the application of the intelligent control system to new power plants.
Method Based on the traditional DCS, the intelligent control system adopted a new hardware architecture, adding intelligent controller, advanced application service network, high-performance timing database and advanced application server, forming a set of basic platform with high computing power, high real-time performance and high open development environment. The needs of the integrated operation control of the unit were met by applying intelligent monitoring panel, intelligent alarm, predictive control of unit coordination optimization, intelligent soot optimization system and other intelligent applications in the intelligent control system.
Result Through the application of intelligent control system and advanced algorithm, the intelligent level of the unit was greatly improved.
Conclusion With the gradual promotion and successful implementation of the intelligent control system in the power generation industry, the intelligent control system is increasingly mature, and all kinds of intelligent applications will be increasingly rich and mature, directing the development of the future production control system.
