Design And Implementation Of The Integrated Automation Protection System For Substations

Integrated automation protection system of transformer substation is the application of electrical automation technology, computer technology, communication network technology and other high-tech in the transformer substation. According to the automation system of transformer substation of Aluminum Corporation of China, Zhengzhou Institute, the key technologies of design and implementation of integrated substation automation protection system were studied, the main contents are as follows:(1):Reviewed the concept and development of integrated automation protection system of transformer substation and the key technologies of the system.(2):On the basis of research on the technology of computer automated protection system, the key theory and technology of computer automated protection system were studied, including the main structure, the main function of the layers of the hierarchical and distributed as well as internal network communications technology(3):Design a hierarchical distributed computer integrated substation automation protection system after consideration the forward-looking, rational, applicability, economic circumstances of the design. The overall principle and the technical route of the design were proposed. The main structure and function of each level of the hierarchical distributed computer automated protection system and the principle of computer relay protection device were studied.(4):The background monitoring systems was designed, the main properties and characteristics of the background monitoring software were analysised.(5):The principle of interference and the corresponding preventive measures were studied.
