Design And Implementation Of Relay Protection Operation Management And Statistical Analysis System

State Grid Information Center adopts protection operation management and statistical analysis system to achieve the daily management of the relay protection of power sector,a good computer system can help staff better finish the work so as to improve the efficiency.At present,most of the electric power industry business center still use manual patterns to complete some protection work,It is not only a waste of energy and a waste of time,but also the error rate is very high.With the development of information technology,computer can be used to complete the work of relay protection,automation and intelligent management.In addition,work related to the relay protection is more complex,and some errors or omissions perhaps occur.In order to make the relay protection more reasonable,more scientific,a convenient power sector standard in daily management is very important,which can raise the work efficiency of enterprise staff and relay protection operation management,as a result,statistical analysis system design and development is necesarry.Under the background of this research,the author studies the operation management and statistical analysis system of relay protection.The main work of this paper is to complete the research and analysis of relay protection operation management and statistical analysis system database design and the corresponding function modules by way of combining structured and object oriented implementation research and analysis of the development environment and development methods.From the point of system convenience and security,the three tier MVC architecture based on B/S is an ideal choice for structuring the system.This paper descripts each module of the system,and emphasizes on the system by the proper technology.The relay protection operation management and statistical analysis system is designed and developed specifically for the management of relay protection related work of the electric power department.The design of the information system is designed to improve the efficiency of the system.In the part of system requirement analysis,the author firstly expounds the overall business background,the module division and the use case analysis,and then explains the system requirement modeling and system data modeling.In the part of system design,the system architecture,database system and system function are designed.The system is divided into the parameters of management,operation management,statistical management,data transmission management,system management module.It is a unified arrangement of the parameter management in the operation condition.Operation management and implementation of relay protection fulfils operation in the process of some of the key processes of data processing,statistical management is for the collection of system real-time relay protection data analysis and processing to the user provides decision-making reference.Data transmission management is the basic data required to complete the operation of the program and the data transmission of relay protection.At the same time,according to various data,reasonable setting and adjusting the basic data of the system.Users of the system management module is a system administrator,access to the system administrator,management system as a whole logic processing and performance optimization,in-depth understanding and analysis of each state in the running process of the system,statistical system operating parameters,inquiring and arranging the background data.In the last,the system of functional testing,through in-depth analysis of the system test results show that the system both on the validity of the design and program implementation is feasible,in line with the requirements of the established design.Users in the use of the system's response to good effect,to meet the user's actual needs of the relay protection operation management and statistical analysis system.
