【摘要】：对电力通信网支撑系统进行安全风险评估,及时发现网络所面临的风险,对电力系统的安全运行具有重要意义。本文研制了一套电力通信网支撑系统安全风险评估系统,通过对电源系统、网管系统、通信机房及运行人员分别建立完备的评估指标体系,利用层次分析法实现了对各模块的风险评估功能。本文在分析研究风险评估技术及相关理论方法的基础上,将风险评估应用到电力通信网支撑系统中,结合电力通信网的特点,确定了电力通信网支撑系统的风险评估的指标体系及评估方法,开发了基于Web服务的电力通信网支撑系统安全风险评估系统。在需求分析阶段,分析了系统的数据需求及功能需求,确定了系统的三个子功能模块：数据维护、评估计算、记录查询。在系统开发方案研究阶段,确定了以Myeclipse为开发工具,以Microsoft SQL server作为后台数据库,采用B/S模式和JDBC数据库访问方式进行系统开发。在系统设计阶段,分别对系统的组成结构、主程序及各功能子程序流程、数据库表以及支撑系统指标体系进行了设计,为了实现系统的灵活性与可维护性,系统设置了多种数据管理维护功能。最后,开发实现并测试了软件系统的各项功能。测试结果表明,系统使用方便、界面友好,满足功能需要和灵活性要求,具有较高的实用性。
[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.
