摘 要 电力电网电能损耗(简称线损)是国家考核电力部门的一项重要经济指标,也是表征电力系统规划设计水平、生产水平和经营管理水平的一项综合性技术经济指标。电力网在输送电能时产生的电能损耗直接影响电力的使用效率和经济效益。随着电力体制改革的日益深化,降低线损越发显现出重要性,本着“技术线损最优化、管理线损最小化”的降损理念,使专业管理由粗放型转向科学、规范的良性循环,从而降低供电成本,提高供电企业经济效益,开发一个线损分析系统是当务之急,也是本论文选题的重要意义和研究宗旨。 因此本人结合工作性质和对线损分析的要求,对Microsoft Access数据库管理系统、Visual Basic应用程序设计,Visual Basic数据库技术进行了较深入的学习和应用,主要完成对线损分析系统的需求分析、功能模块划分、数据库模式分析,采用了自顶而下、逐步细化、模块化的设计理念,并由此设计了数据库结构和应用程序。系统运行结果证明,本文所设计的线损分析系统可以满足分析线损、降低供电成本的需要。 关键词:线损, Microsoft Access,Visual Basic,数据库组件,窗体,控件 Abstract
The electric power electrical network electrical energy loses (abbreviation line to damage) is a national inspection electric power department's important economic indicator, also is attributes the electrical power system plan design level, the production level and a management management level comprehensive technology economic indicator. Electric power network when transportation electrical energy produces the electrical energy loses the direct influence electric power the use efficiency and the economic efficiency. Along with the electric power organizational reform daily deepening, reduces the line to damage even more appears the importance, "damages in line with the technical line the optimization, the management line damages slightly" falls damages the idea, causes the specialized management to change the science, the standard positive cycle by the extension, thus reduces the power supply cost, enhances the power supply enterprise economic efficiency, develops a line to damage the analysis system is the urgent matter, also is the present paper selected topic vital significance and the research objective. Therefore myself unify the work nature and damage the analysis to the line the request, to Microsoft the Access database management system, Visual the Basic application programming, Visual the Basic data bank technology has carried on the thorough study and the application, mainly completes to the line damages the analysis system the demand analysis, the function module division, the database pattern analysis, used from has gone against but under, is gradually thin, the modular design idea, and from this has designed the database structure and the application procedure. The system movement result proved, this article designs the line damages the analysis system to be possible to satisfy the analysis line to damage, to reduce the power supply cost the need.
