[Abstract]:It is of great significance for the safe operation of electric power system to evaluate the security risk of the power communication network support system and discover the risks faced by the network in time. In this paper, a security risk assessment system for power communication network support system is developed. A complete evaluation index system is established for the power supply system, the network management system, the communication computer room and the operator, respectively. The risk assessment function of each module is realized by AHP. On the basis of analyzing and studying the risk assessment technology and related theories and methods, this paper applies the risk assessment to the electric power communication network supporting system, and combines the characteristics of the electric power communication network. The index system and method of risk assessment of power communication network support system are determined, and the security risk assessment system of power communication network support system based on Web service is developed. In the stage of requirement analysis, the data requirement and function requirement of the system are analyzed, and three sub-functional modules of the system are determined: data maintenance, evaluation and calculation, and record query. In the research stage of the system development scheme, the system is developed with Myeclipse as the development tool, Microsoft SQL server as the background database, B / S mode and JDBC database access mode. In the stage of system design, the structure of the system, the main program and the flow chart of each function subroutine, the database table and the index system of the supporting system are designed respectively, in order to realize the flexibility and maintainability of the system. The system has set up a variety of data management and maintenance functions. Finally, the functions of the software system are developed and tested. The test results show that the system is convenient in use, friendly in interface, meets the requirements of function and flexibility, and has high practicability.
