【摘要】 配电管理系统(DMS)是一个符合配电网现代化需求的综合自动化系统，它一般包括以下功能，配电自动化(DA)、地理信息系统(GIS)、配电工作管理(DJM)、配电网高级应用软件(D-PAS)、故障投诉电话管理(TCM)、用电营业管理(SM)、电能计费(EET)、负荷管理(LM)等。配电网高级应用软件主要是网络分析软件，它为调度人员、运行人员以及计划人员提供了在规定条件下分析配电系统的手段。以配电网络分析为核心形成的丰富多彩的配电应用软件，可以分为基本软件和派生软件两部分，进一步还可以分出一部分专用软件。DMS网络分析的基本软件有：网络结线分析、潮流计算、状态估计、负荷预报、短路电流计算、电压／无功优化等。派生软件有：负荷控制、电容器优化配置、变压器与馈线负荷分配、电源阻抗计算等。网络分析软件是有力的调度工具，通过它可以了解和掌握当前的运行状态，从而挖掘安全和经济方面的巨大潜力。本文运用面向对象的程序设计方法结合计算机图形学的知识，开发了一套可视化配电网分析软件平台，它包括用于绘制电力系统结线图的图形模块、用于保存、浏览、修改电网数据信息的数据库模块和进行配电网潮流计算的计算模块。整个系统完全按照面向对象的程序设计方法设计，图形模块、数据库模块、计算模块浑然一体，在图形界面上实现对数据的输入、计算与管理。系统有较好的开放性，编写其他功能模块的程序后可以很容易加入到现有的系统中，已有的代码基本上不需要改动。文中对各种配电网潮流计算方法进行了比较分析，选用了性能较好的交替迭代算法进行了潮流计算，计算结果表明，本软件平台是高效的、正确的。本软件平台是DMS的重要组成部分，下一步将加入短路电流计算、理论线损计算、电压／无功优化、状态估计、负荷预报等功能。更多还原

【Abstract】 DMS (Distribution Management System) is an integrated comprehensive automation system which accord with the development of moden distribution system. The DMS include all of the following function, DA (Distribution Automation), GIS (Geographical Information System), DJM(Distribution Job Management), D-PAS(Distribution Powerful Application Software), TCM(Trouble Call Management), SM(Service Management), ET (Electric Energy Tariffing), LM (Load Management), etc. The fundamental component of DMS is networks analysising. The distribution software centered network analysis is divided into two components: basic software and derived software. The basic software consists of topology analysis, on-line load flow computation, state estimator, security analysis, dispatchers training simulator, short circuit current computation, and voltage/ reactive power optimize, etc. The derived softwares consist of load control, capacitor optimizer configuration, transformer and feeder load distribution, impedance computation of generator, etc. Network analysis software is powerful dispatch tool, though witch the current state of the power system can be realize, then improve the security and economic potential. The paper presents a distribution analysis software platform which is developed combining computer graphical theory and OOP (Object-Oriented Programming). The platform includes three modules, the graphics module, the database module and the computation module. The graphical module can draw the key diagram of power system; the database module can save, browse and edit the data of power systems; the computation module can compute the power flow. The whole system is designed under the OOP ideology. The three modules integrate into a whole system, all the data of distribution systems can be input, management and compute through the -graphical interface. The system also is a open system, that is to say other modules can easily add into the system in the near future, however the existing codes hardly need modify. The paper chooses the alternate iterate algorithm after made a compare with all kinds of power flow computation algorithms. The results of the two examples indicate that theplatform is efficient and accurate. As an essential component of DMS, the system will supplement itself in the following aspect, short circuit current calculation, theoretical losing, voltage/reactive power optimize, state estimation, load forecast, etc.更多还原
