[Abstract]:With the continuous development of social economic construction and the continuous application of various high and new technologies, the power quality and the reliability of power supply have been updated and higher requirements, in order to meet the increasing social needs, It is the primary goal of electric power enterprises to improve the power supply capacity, improve the structure and reliability of power network, and improve the degree of comprehensive automation. The detailed requirements and manufacturing standards of substation integrated automation system in China are not perfect. It is an important trend of future development to configure a set of ideal automation system reasonably. This article mainly carries on the research from the following several aspects: 1. This paper first summarizes the automation integrated system, analyzes the research trend of substation integrated automation system at home and abroad, and finally introduces the source and background of the subject. The research object comes from the transformation project of automatic monitoring system in 500kV Shaping substation, which requires the substation integrated automation monitoring system to run efficiently, real-time and reliably, and to monitor and manage the equipment in the substation. At the same time, it is necessary to exchange and share information in real time and effectively with the power grid system to improve the security and stability level of power grid. The overall design scheme of substation integrated automation system is presented. It includes the classification of the system architecture, the requirement analysis of the substation integrated automation system, and the overall structure diagram of the system. Combined with the actual situation of 500kV Shaping substation system, the substation integrated automation monitoring system is divided into three levels according to the hierarchical and distributed construction. The hardware of the system is the foundation and premise of the whole system, which should satisfy the principles of reliability, openness, stability and practicality, so as to realize the high precision remote monitoring, real-time telemetry and remote signal acquisition of substation system. Realize the integration of function execution. The whole hardware system mainly includes the measurement and control device, the electric power data telemetry unit, the computer and its network transmission equipment, the man-machine interactive equipment / GPS timing system, other external equipments and so on. The integrated automation system of Shaping 500kV substation is a large software system, which is the fusion of many software technologies. The following seven key technologies are studied in the whole system: multithread data acquisition and can network communication, Multi-channel data release system, high performance multi-layer database, intelligent electrical analog diagram display platform, system security system and background monitoring, external information exchange and sharing platform .5. Finally, the paper gives the concrete physical drawing of the whole system, including the display of the main interface, the data acquisition equipment, the user management interface and so on. The developed substation integrated automation monitoring system has been used in 500kV Shaping substation. The operation results show that the system is stable, the equipment is in good condition, the design is reasonable, and the automation level of the whole system is improved. In this paper, through the whole process design of the comprehensive white monitoring system in Shaping 500kV substation, the functional requirements of substation integrated automation are analyzed, and its development process and direction are discussed, and the premise of product and market is investigated. In this system, the hierarchical and distributed structure based on bus is constructed, the equipment is rationally selected and configured, and some functions of some products are improved according to the actual situation in the field. The transformation of the substation self-contained system has been completed and finally implemented.
