直流输电可靠性管理统计评估系统设计

Design for Reliability Management and Statistic Evaluation System of DC Power Transmission System

为提高我国直流输电可靠性管理水平,开发了直流输电可靠性管理统计评估系统。该系统已经在全国得到推广应用,系统以直流输电可靠性规程和现场实际需求等作为设计依据,并在此基础上采用最新的软件开发架构和技术进行了系统的开发。对直流输电可靠性规程相关概念作了明确剖析,包括事件状态分类、能量可用率、双极停运、综合检修、计划停运超时等。并从技术特点、体系结构和功能特点等方面介绍了系统。系统的体系结构分为整体运行架构、功能模块结构和数据库结构,在对三种结构分析基础上阐述了j2ee架构下采用组件化开发模式进行系统软件设计的思想。最后,针对直流输电可靠性管理工作的意义及发展提出了一些见解。

For sake of enhancing reliability management level of direct current power transmission system in China, the reliability management statistic evaluation system of direct current power transmission system is developed. This system has been applied all over the state at the request of electric power reliability management center of china electricity council. The system is designed based on the reliability evaluation code for direct current power transmission system and actual scene requirement. Moreover, it adopts the latest software development framework and technology to complete the development of the system. In the article, it makes an clear anatomy for the relative concept of the reliability evaluation code for direct current power transmission system, these concepts includes event state class, energy availability, bipole outage, composite examine and repair, the overtime of scheduled outage etc. The paper also introduces the system including its technology characteristic, system structure and function feature etc. The technology characteristic of this system includes j2ee, java, design pattern, structs, mvc, jsp, servlet, javascript, b/s, oracle, store procedure, trigger, tomcat, log4j, ant etc. For system structure, the paper makes an analysis through three aspects which includes whole operation framework, function module structure, data base structure. From this analysis, you can know how to adopt a component development pattern to design program under the j2ee platform. As function feature of system, it gives some perfections of examine object, business management flow, user management and input of basic event etc. At last, the paper gives some opinions about the meaning and future development of the direct current reliability management work.
