Design of General Intelligent Control Platform for Thermal Power Plants

Intelligent control system (ICS) is a new type of control system that combines advanced intelligent control technologies, such as big data and artificial intelligence, with traditional DCS, and it is the development direction of realizing production process intelligence in thermal power plants. In this paper, for the third-party intelligent applications other than DCS manufacturers, and in view of the deficiencies of existing intelligent control systems in terms of integration and extensibility, we propose a general intelligent control platform architecture design based on "microservices + containerization" and "unified interface + modularization". The platform integrates DCS internal communication interface and human-computer interaction interface, realizes the integrated monitoring and closed-loop control of general intelligent control platform and DCS, and is compatible with a variety of DCS and intelligent applications developed in different programming languages. The successful on-line operation of the general intelligent control platform on a 600MW unit of a power plant has verified the rationality and effectiveness of the system architecture design.
