摘 要 本课题主要用于电力系统规划设计人员确定经济合理、技术可行的规划设计方案；运行调度人员确定系统运行方式、分析系统事故、寻求反事故措施；科研人员研究新设备、新元件投入系统等新问题以及高等院校用于教学和研究。Abstract This topic mainly uses in the electrical power system plan designers determining that the economy is reasonable, technical feasible plan design proposal; The traffic control personnel determined that the systems operation way, the analysis system accident, seeks the counter-accident measure; The scientific researchers study the new equipment, the new part to invest the system and so on new question as well as the institutions of higher learning use in the teaching and the research. This topic use structurization method carries on the development to the system, first has carried on the detailed investigation understanding users demand and the present systems condition to the system, then from aspects and so on system feasibility, system analysis, system design conducts the research, and uses massive tools and so on flow charts, data dictionary, structure drawing and data sheet carries on the detailed description to systems analysis and the design, when the system implementation uses PowerBuilder9.0 to take the development kit, 2000 established one take SQL Server as the backstage database simple and direct, practical, to be possible to solve the actual problem system. Uses the method which the black box test and white box test unifies to the system to carry on the test. This systems function mainly includes the asymmetric failure, the tidal current computation, the conductance changes the impedance, Gauss eliminates, the node optimizes, the static computation, modules and so on three-phase short circuit, realize functions basically and so on data increase, deletion, revision, inquiry, printing. Key words：Electronic Power Synthesis computation；Management Information System；Power Builder 目 录 摘要 I Abstract II 第1章 绪 论 1 1.1 选题背景及意义 1 1.2 国内外发展状况 1 1.3 论文使用的研究方法与工具 3 1.4 论文的基本思路与逻辑结构 3 1.5 本人所做的工作 3 第2章 可行性分析 4 2.1 概述 4 2.2 现行系统的调查与分析 4 2.2.1业务流程调查 4
