Abstract

Security for a conventional substation system run low, controllable power quality, operation and maintenance of the heavy workload and other issues, the design of an integrated substation automation monitoring system based on intelligent control to monitor for real-time operation of the substation substation the computer monitoring system is the use of object-oriented design ideas, and relying on computer technology, network communication technology, modern control technology and graphics display technology substation set control, measurement and modern management feature set for the integrated automation systems.

The actual problems of the of the papers needle site and the current development trend of substation monitoring system and substation monitoring special process, the basic characteristics and requirements of the 110KV substation integrated automation control system design. The actual problems of the of the papers needle site and the current development trend of substation monitoring system and substation monitoring special process, the basic characteristics and requirements of the 110KV substation integrated automation control system design.

The substation is an important part of the power system, and its role is to transform the voltage, the collection and distribution of electric energy, therefore, substation safe and reliable operation is closely related to the development of the national economy. With the continuous expansion of the installed capacity of the power system and power supply geographical, power quality, supply reliability, running economy are increasingly high requirements. In order to achieve high-quality, safe, reliable, economical operation requirements, it is economically reasonable, technologically advanced substation monitoring and protection system must be established, namely substation automation. In recent years, the substation computer monitoring and protection technology development exciting, especially substation integration of computer monitoring and protection integrated substation automation design ideas and promote the realization of the unmanned substation, can take advantage of remote technology to grid scheduling quickly and accurate access to the the substation operation of real-time information, a complete grasp of the real-time operating status of the substation, discover substation protection and make the appropriate decision-making and processing.
