Relay Protection Setting Value Management System Design And Implementation

Relay Protection is the key of the power system, to ensure the grid security, stability, economic operation and intelligent control, the relay protection system has played an irreplaceable important role. With the expanding of the grid, the development of the smart grid, grid operation mode tends to be more and more complicated, after the changes in the operating mode to achieve operation mode and protection device setting combined optimally, can effectively ensure the grid security, stability and economically be in motion, which require the relay protection setting management accurately, effectively, promptly.Based on modern computer technology, network information technology and management theory, the research of relays protection setting management system from city-level power supply enterprises this paper based on a careful analysis of the characteristic works on relays protection setting management, this paper mainly discusses the researches on relay protection setting management system such as computer technology, workflow concept, system design and achieve work. From the current development of similar systems in the world, software development technology, system design, database, network operating system platform, etc., on the development of relay protection setting management system involves comparison and selection of relevant technologies, combined with the actual work in city-level power supply enterprises need to be seriously analysis, and explain the management of relay protection setting combined with the workflow technology to determine the appropriate technical solution of the system. In accordance with the software engineering theories and methods,the overall structure and function from the system analysis, system platform, system appearance, database technology, etc. to determine the structure and functions of the whole system was constructed based three relatively separate: user layer, application layer, service layer, and this system making the management of relay protection setting intelligence, networking, automation, to achieve a setting value requisition management responsibilities clear, easy to operate, efficiency and economize.
