【摘要】：自开展电网信息化道路以来,电网公司相继建设了负荷控制系统、厂站遥测系统、配变监测系统和低压用户集中抄表系统,大幅提高了电力计量的自动化管理水平,提升效果显著。随着社会客户需求的逐步提高,对计量自动化的要求越来越高,电网改造的升级与完善,电网公司将继续推广以上系统的覆盖范围,为了提升对居民用户电量数据的管理和应用,提升供电可靠性,电网公司急需加强对低压用户集中抄表系统的覆盖与实施。低压用户集中抄表系统是综合现代计算机与通信网络技术的信息自动化系统,系统通过对低压居民计量表计数据准确及时采集和统计分析,从而快速、全面地反映低压用户电量使用情况,为电网企业营销客户管理提供可靠数据保证。本论文通过对低压集抄系统总体设计,通信采集方式的研究,并根据不同的地域情况,从而选择不同的采集方式,提高电网企业采集电量信息的经济效益。本文通过研究低压集抄系统的总体设计方案,采集方式等,并从低压集抄工程设计原则、施工规范、验收规范,并根据实际的问题制定相应的运维措施。从中因地制宜的分析出不同低压集抄通信采集技术的利弊,实现集中抄表系统主站对低压用户电能信息的自动采集。低压居民集中抄表系统的推进,能够进一步提升供电局电费回收率,有效防范电费风险,在低压集抄工程实施过程中同步改造费控电能表及相关设施,实现费控功能,降低了供电企业的管理成本,降低了催缴电费的人力投入,提高了供电企业的管理效率。同时本论文通过研究改造集中器、采集器、电能表及各设备间的通信信道,挖掘出不同采集方式的利弊,实现集中抄表系统主站对低压用户电能信息的自动采集。从而实现低压用户月冻结数据的自动采集,用于营销计费结算;另外,为抄表结算、停电统计、线损监测、故障监测等计量业务提供系统化的支持手段,为智能用电提供技术支持。在具体的工程技术应用方面,本研究针对江门蓬江供电局小区开展RS-485方式集中抄表试点技术进行了专项研究,并根据研究的技术方案,从工程的实施的现状及需求分析提出工程建议,在组网原则、建设原则、主站方案、通信方案、实施方案方面都有的放矢的制定了相应的措施,同时还规定了相关设备的配置原则,安装技术要求和推广措施,并选择了相应的试点小区进行实施,从而实现对低压居民用户电量负荷的集抄统计。
[Abstract]:Since the development of power network informatization, the power grid company has built load control system, plant station telemetry system, distribution transformer monitoring system and low voltage user centralized meter reading system, which has greatly improved the level of automatic management of electric power metering. The effect is remarkable. With the gradual improvement of social customer demand, the requirement of measurement automation is becoming higher and higher, and the power grid transformation will be upgraded and perfected. The power grid company will continue to promote the coverage of the above system. In order to improve the management and application of the electric quantity data for the residents and to enhance the reliability of the power supply, the power grid company urgently needs to strengthen the coverage and implementation of the centralized meter reading system for the low-voltage users. The centralized meter reading system for low-voltage users is an information automation system that integrates modern computer and communication network technology. The system collects and analyzes the data of low-voltage residential meter accurately and timely, so as to be rapid. It comprehensively reflects the usage of low-voltage customers and provides reliable data guarantee for marketing customer management of power grid enterprises. In this paper, the overall design of the low voltage collection system, the study of the communication acquisition method, and according to the different regional conditions, we choose different acquisition methods to improve the economic benefit of the electric power information collection in the power grid enterprises. In this paper, the overall design scheme and collection method of the low voltage collection and reading system are studied, and the design principles, construction specifications and acceptance codes of the low voltage collection system are studied, and the corresponding operation and maintenance measures are worked out according to the actual problems. This paper analyzes the advantages and disadvantages of different low voltage collection communication acquisition technology according to local conditions, and realizes the automatic collection of low voltage users' electric energy information by the main station of centralized meter reading system. The advance of the centralized meter reading system for low-voltage residents can further enhance the electricity recovery rate of the power supply bureau, effectively guard against the risk of electricity charges, and synchronously retrofit the fee-controlled watt-hour meter and related facilities during the implementation of the low-voltage centralized reading project, so as to realize the cost control function. It reduces the management cost of the power supply enterprise, reduces the manpower input of calling the electricity bill, and improves the management efficiency of the power supply enterprise. At the same time, by studying the communication channel between concentrator, collector, watt-hour meter and various equipments, this paper excavates the advantages and disadvantages of different acquisition methods, and realizes the automatic acquisition of low-voltage user electric energy information by the main station of centralized meter reading system. In order to realize the automatic collection of monthly frozen data for low-voltage users, it can be used for marketing billing and settlement. In addition, it provides systematic support means for metering business such as meter reading, outage statistics, line loss monitoring, fault monitoring and so on. Provide technical support for intelligent power consumption. In the concrete engineering technology application aspect, this research has carried on the special research to the Jiangmen Pengjiang Power supply Bureau small area to carry on the RS-485 way centralized meter reading pilot technology, and according to the research technical plan, Based on the analysis of the present situation and demand of the project implementation, the paper puts forward some engineering suggestions. In the aspects of network principle, construction principle, main station scheme, communication scheme and implementation plan, the corresponding measures are formulated.
