Design and application of parallel intelligent control system for denitration system in coal-fired power plant

Abstract

Based on the parallel control theory, a denitration parallel intelligent automation system is designed in this paper. It is composed of hardware system and software system. The hardware system has modules such as power supply, industrial controller and host, and real-time communication is realized between the control modules. The software system is based on the parallel control theory. Firstly, the pseudo-random sequence module, period data acquisition module, identification module, predictive control module and other modules are realized, and the specific basic functions are given;Secondly, the relevant modules and logic systems corresponding to manual system, calculation experiment and parallel execution are designed, the specific structure of denitration parallel control system is given, and the structure of parallel process controller is analyzed in detail;In this paper, it is proposed that the program-controlled signal flow is the key to realize the intelligent operation of parallel control, and the specific design method is given. At the same time, the virtual machine simulation operation in the hardware system is also an important part of parallel intelligent control, and the specific signal communication mode is given. Finally, an engineering application example of denitration parallel intelligent automation system is given, and the effectiveness of the system is verified by experiments, The design method proposed in this paper has strong practical significance for the application of parallel intelligent automation system.
