【摘要】：随着近年经济的发展,人民的生活水平的提高,我国的电力用户数量越来越多,使得供电企业面临的挑战也逐年增大。一方面是因为电力用户数量增加,必然会大幅度的增加电力部门抄表的工作量,另一方面负荷用电的时段增加,电力生产压力增大,对计划调度以及经济调度的要求也随之增加,更加突出了电力供求之间的矛盾。为了解决供求矛盾,提高用户满意度,实现削峰填谷和科学合理用电,具有实时抄表、稽查监控、需求侧管理功能的用电信息采集系统应运而生。用电信息采集系统能够实时监控用电现场并且对用电现场进行在线检测,实现准确的进行数据抄读的同时并能保证这些数据得到及时的、准确的传输,这样监控中心对现场电能表的管理就能更加方便、快捷,大大提高工作效率,以达到优化整个系统的目的,实现资源的优化配置,大幅度的节省人力、物力和财力,也为企业降低成本,提升用户满意度,提高经济效益提供了切实有效的方法。本文主要将根据智能电网发展的实际需求,对国网满城供电公司韩村供电所辖区内村居民及非居民用户用电信息信息系统进行分析与应用,并重点对高级应用模块中的线损分析功能及负荷监测功能进行测试分析。本文完成的的主要工作包括:(1)首先分析了国内外远程抄表的情况,根据这种现状,分析并明确用电采集系统的功能需求,依据《电力用户用电信息采集系统功能规范》,同时结合满城区韩村供电所的实际情况,设计出用电采集系统的总体架构,并分析用电采集系统的关键技术。(2)用电信息采集系统的通信信道的分析。用电信息采集系统的通信信道可分为两部分:远程通信信道和本地通信信道。主站系统与采集终端之间的通信信道是为远程通信信道,远程通信技术包括GPRS无线公网、CDMA无线公网中压电力线载波等;各个采集终端之间或采集终端与智能电表之间的通信信道称为本地通信信道,本地通信技术一般包括低压电力线载波、RS-485总线、微功率无线技术等。(3)对用电信息采集系统的主要业务进行了流程分析与交互界面的展示,对主站软件进行测试,重点对线损分析模块应用情况进行分析,帮助电力企业找出线损异常的根源,及时做出调整,降低线损;应用负荷分析模块监测异常负荷,迅速找出故障点或发现窃电用户,挽回供电企业损失。测试结果说明用电信息采集系统的应用不仅解决了传统抄表模式耗费大量人力物力的弊端,而且提高了抄表准确率,降低了线路损耗,极大的提高了国网满城韩村供电所的经济效益和客户满意度。
[Abstract]:With the development of economy and the improvement of people's living standard in recent years, the number of electric power users in our country is more and more, which makes the challenges faced by power supply enterprises increase year by year. On the one hand, because of the increase in the number of electricity users, it will inevitably increase the workload of meter reading in the power sector by a large margin. On the other hand, the period of time spent on load electricity will increase, and the power production pressure will increase. The demand for planned dispatch and economic dispatch is also increasing, which highlights the contradiction between power supply and demand. In order to solve the contradiction between supply and demand, improve customer satisfaction, realize peak and valley cutting and scientific and reasonable electricity consumption, a power information collection system with real-time meter reading, checking and monitoring, and demand side management functions emerges as the times require. The power information acquisition system can monitor and monitor the power scene in real time and carry on the on-line inspection to the electricity field, realize accurate data reading and reading, and can guarantee these data to get timely, accurate transmission at the same time, In this way, the management of the on-site watt-hour meter by the monitoring center can be more convenient, fast, and greatly improve the working efficiency, in order to achieve the purpose of optimizing the whole system, to realize the optimal allocation of resources, and to save manpower, material resources and financial resources by a large margin. It also provides a practical and effective method for enterprises to reduce cost, improve customer satisfaction and improve economic efficiency. According to the actual demand of the development of smart grid, this paper will analyze and apply the power information system of village residents and non-residents within the jurisdiction of Hancun Power supply Station of Mancheng Power supply Company. The line loss analysis function and load monitoring function of advanced application module are tested and analyzed. The main works of this paper are as follows: (1) first of all, the situation of remote meter reading at home and abroad is analyzed. According to this situation, the functional requirements of the electric power acquisition system are analyzed and defined. According to the function Standard of Electric Power user Power Information Collection system and the actual situation of Hancun Power supply Station in Mancheng District, the overall structure of the power acquisition system is designed. The key technology of the electric power acquisition system is analyzed. (2) the communication channel of the electric information acquisition system is analyzed. The communication channel of electrical information acquisition system can be divided into two parts: remote communication channel and local communication channel. The communication channel between the master station system and the acquisition terminal is a remote communication channel. The remote communication technology includes GPRS wireless public network / CDMA wireless public network medium voltage power line carrier and so on. The communication channel between each acquisition terminal or between the acquisition terminal and the intelligent meter is called the local communication channel. The local communication technology generally includes the low voltage power line carrier RS-485 bus. (3) the main business of the power information acquisition system is analyzed and the interactive interface is displayed, the main station software is tested, and the application of the line loss analysis module is analyzed. Help electric power enterprise to find out the source of abnormal line loss, make adjustment in time, reduce line loss; use load analysis module to monitor abnormal load, quickly find fault point or find out the power stealing user, and recover the power supply enterprise loss. The test results show that the application of the electric information acquisition system not only solves the drawback of the traditional meter reading mode which consumes a lot of manpower and material resources, but also improves the accuracy of meter reading and reduces the line loss. It greatly improves the economic benefits and customer satisfaction of Hancun Power supply Station in Mancheng.
