摘要
电力是国民经济的命脉与支柱,它在现代社会的发展进程中始终占有举足轻重的地位。地理信息系统(GIS)是具有地理数据获取、存储、编辑、处理和现实功能的计算机软件系统。将GIS引入了电力系统,更能极大的方便电力数据图形的管理,大幅度的提高了工作人员的劳动生产率,改进了供电公司的管理水平。
本文讨论的0.4kV低压配电资源管理系统是充分利用GIS、GPS、CAD、网络、数据库等信息化技术,结合当前低压配电网络的实际管理需求,分析其空间数据、属性数据的基本特征,设计合理的空间数据模型,给出数据库设计与实现的解决方案,为低压配电网管理者提供一个低压配电网的缩微化模型。达到低压配电网管理实现信息化、直观化、科学化、规范化和自动化的目标;将低压配电网GIS系统建设成整个配电网信息共享平台,统一录入、删除、修改低压配电数据,避免重复劳动,为低压配电网管理、规划设计、故障维护等提供信息支持;实现对0.4kV低压网的地理分布、网络拓扑、设备参数、低压用户分布等基础资料进行电子化管理。和传统的以设备属性为主的电力MIS相比,本文研究的重点和创新点在于研究如何以“图模”一体化的方式建立包括图形、拓扑、属性在内的整个低压网络的模型。
文章共分以下四个部分,首先讨论了当前低压配电管理系统存在的问题和实际的需求。第二部分结合低压电网的实际情况,讨论了0.4kV低压配电资源管理系统的设计方案,着重介绍了低压配电网络的建模方式以及低压网络的存储和加载方式。第三部分针对提出的方案,对该系统进行了软件构架设计、系统功能和操作方式的设计。第四部分对系统的总结和展望。本系统的应用为湖州供电公司的0.4kV低压配电网络的管理,建立了统一的数字化电
力系统结构体系。对提高企业信息化水平具有重要的意义,符合电力企业对低压配电网络管理的实际需求。
Electricity is the lifeblood and backbone of the national economy, which plays a vital role in the development process of modern society. Geographic Information Systems (GIS) is a computer software system, which has the functions of acquiring, storing, editing, processing and achieving geographic data. Putting the GIS into the power grid system, people can conveniently manage the pictures of geographic data, and it has greatly improved the labor capacity of the staff as well as the level of power supply company’s management.
The resource management system of 0.4kV low-voltage power distribution makes full use of the information technologies of GIS, GPS, CAD, networks, databases and so on. Combined with the actual management requirements of current low-voltage power distribution grid, this article analyzes the basic characters of its space and attribute data, designs a reasonable model of space data, gives a solution for the design and achievement of database, and provides a low-voltage distribution power grid miniature for the administrators, it can achieve the target of informatization, visualization, scientification, standardization and automation of the administration of low-voltage distribution power grid. The paper uses the GIS system for designing an information-sharing platform for the entire distribution power grid; it unitedly inputs, deletes, and modifies the low-voltage distribution data; it also avoids repeat efforts, and offers technology supports for the administration, designing, bug maintenance and so on; achieves electronic management of the basic information of 0.4kV low-voltage power grid’s geographical distribution, network topology, device parameter, low-voltage distribution for users, etc.. Compared with the traditional power-based MIS device properties, the emphasis and innovation of this paper is on researching how to set up a whole low-voltage power grid model which includes graphics, topology and attributes through the way of“map model”of integration.
The following article is divided into four parts. Firstly, it discusses the problems and actual demands of current low-voltage power distribution management system. Secondly, it mainly talks about the design proposal of 0.4kV low-voltage power resource management combined with the actual situation of low-voltage power grid, and it also focus on introducing the modeling approach and the storage and loading methods of low-voltage power grid. In response to the third part of the program, the paper proposes a design of software architecture, system function and operation mode. At last, it presents the conclusion and outlook of the system.
The application of this system is for the management of 0.4kV low-voltage power grid in Huzhou power companies, and it has established a unified digital power system. It plays an important role in improving the information level of enterprises, and shows the actual demands in accordance with the management of low-voltage power grid by power enterprises.
