Application And Research Of Integrated Automation Of Electrical Auxiliary System In Power Plant

With the development of the automation and information technology of Power Enterprise, and the propulsion of the electricity market, It is becoming the most popular topics for power enterprises to adopt more advanced automation control technology and products, enhance the level of operation and management of power plant automation, save energy and reduce consumption, and strengthen the competitiveness of enterprises.To enhance the management level of the power plant automation and operations, Integrated automation of electrical auxiliary system synthetically applies the advanced computer control technology, the protection of computer monitoring and control technology, the communications technology and database technology and so on, realizes the functions of operation, protection, control and fault information management.This paper introduced the course of historical development of the electric power plant control, focus on the application of industrial Ethernet technology, communications middleware technology, real-time initiative data push technology ect., considers fully the function division and the coordination control between the automation system and the DCS system, proposes the reasonable solution.According to the characteristics and functional requirements of electrical auxiliary system, the design ideas and solutions of the integrated automation of electrical auxiliary system that based on Industrial Ethernet has been proposed. According to the difference of the unit capacity and the scale, the standard configuration and the economy configuration have been designed, and focus on the monitoring platform architecture of the main station. Finally, through the practical application, the feasibility, rationality and advanced of the system has been verified.
