Coal-fired Power Plant Electrical Control Systemdesign Based On Network Communication Technology And Research

With the continuous development of China's power industry,generating units are constantly to the large capacity and high parameters of the direction of development,which gives the power plant electrical automation level has put forward more and more high requirements.However,the development of automatic monitoring technology of power plant in China,especially in thermal power plant is slow,and the rapid development of the electric power industry has become more and more obvious.This paper puts forward the overall design scheme of electrical monitoring and control system based on network communication technology in view of the deficiency of the electrical automation system of domestic thermal power plants in China.In this paper,the communication technology using CAN bus technology,so as to achieve the monitoring of the entire power plant.In this paper,firstly,the research status of the domestic and foreign power plant monitoring system is analyzed,and then the design of the power plant power control system designed by the system is analyzed.This system first introduces the monitoring system of the main monitoring methods and the overall framework of the design.Secondly,the hardware design and the communication scheme of the monitoring system of the thermal power plant are introduced.The hardware design of the system uses 32 bit embedded control unit and 16 bit analog to digital conversion unit,and gives the corresponding communication interface driver design.The design method of multi task real-time operating system is mainly used in the software design.In addition,this paper also relates to the matching of monitoring and management system,and describes the function of the management system and the design method of the monitoring management software...
