【摘要】：随着科学技术的发展,人民生活水平的提高,社会用电需求逐年增加。当代电网面临着越来越多的问题,国家电网现有系统仅限于管理电压等级较高的输配电线路,其硬件设施投入成本高,日常维护成本也比较高,不适用于中小城市以及城镇的电网管理。如何加强中小城市以及城镇电网的调度管理,保障电网安全运行,以及提高供电企业自身经济效益是我们研究的重要方向。GIS是“数字化电网,信息化企业”不可或缺的重要技术。论文选取河南省南阳市部分城镇为研究区域,调研现有电力资源发展现状,结合GIS技术对线路的数据采集、资料管理、数据统计汇总等多种电力业务进行需求分析,构建了电网线路数据的管理和分析体系。主要工作如下:(1)对电力网络现状及实际需求进行分析,确定了基于GIS的实体关系模型,筛选出适合配电网络的关键技术。(2)确立数字化电网线路管理系统的设计目标和原则,采集GPS电杆、变压器等数据,将线路按每个杆塔及有关资料逐级录入到数字化地图中,对杆塔和线路等分别处理以形成数字化电网的基本资料,通过地理数据拓扑关系建立电网空间数据库。(3)针对现实电网线路输送过程中损耗问题,探讨线损分析的原理,提出适合程序实现的线损分析流程,为系统计算实际的电网线路损失提供依据。(4)利用MapInfo的MapX组件技术,结合Oracle数据库,建立了基于GIS的数字化电网线路管理系统。通过上述研究,本文提供了采集的杆塔、变压器等外业数据批量导入功能、和台帐自动生成、架空线自动连线的功能,构建电网高级应用计算模拟。并且本文对线路运行控制、线损计算以及电网专题图等高级应用功能做了研究。
[Abstract]:With the development of science and technology and the improvement of people's living standard, the demand for electricity is increasing year by year. Nowadays, the power grid is facing more and more problems. The existing system of State Grid is limited to the transmission and distribution lines with higher management voltage grade. The cost of hardware and equipment is high, and the cost of daily maintenance is also high. Not applicable to small and medium-sized cities and towns power grid management. How to strengthen the dispatching management of small and medium-sized cities and urban power grid, ensure the safe operation of power grid, and improve the economic benefit of power supply enterprises is the important direction of our research. Information enterprise "indispensable important technology." This paper selects some towns of Nanyang City in Henan Province as the research area, investigates the current situation of power resources development, and combines GIS technology to analyze the demand of many kinds of electric power services, such as data collection, data management, data statistics and summary, etc. The management and analysis system of power line data is constructed. The main work is as follows: (1) analyzing the current situation and actual demand of power network, determining the entity relation model based on GIS, selecting the key technology suitable for distribution network. (2) establishing the design goal and principle of the digital power network line management system. The data of GPS poles and transformers are collected, the lines are recorded into the digital map according to each tower and related data, and the basic data of the digital power grid are processed separately to form the digital power grid, such as the pole tower and the line, etc. The spatial database of power network is established by topological relation of geographical data. (3) the principle of line loss analysis is discussed in the process of transmission of real power line, and the flow of line loss analysis suitable for program realization is put forward. It provides the basis for calculating the actual power network line loss. (4) the digital power network line management system based on GIS is established by using MapInfo MapX component technology and Oracle database. Through the above research, this paper provides the functions of mass data transfer from the pole tower, transformer and so on, and the functions of generating the account automatically and connecting the overhead lines automatically, and constructing the advanced application calculation simulation of the power network. Furthermore, the advanced application functions such as line operation control, line loss calculation and power grid thematic map are studied in this paper.
