【摘要】：在供电企业输电、变电、配电、用电等各个环节中,线损管理是其中最为重要的一个指标,其技术和管理是供电企业在电网规划、生产调控、营销经营等多方面综合水平的主要体现。但其管理方式一直比较被动,一个周期内大量数据汇总形成报表后方可分析其中问题,实时性较差,不能及时发现线损管理中的缺陷。随着国家电网公司一系列建设“一强三优”现代化企业目标的实施,对供电企业尤其是基层县级公司的智能化管理水平的提出了更高的要求。近年来,国网临清市供电公司在营销、生产等各个环节上向智能化、信息化的方面发展,以更为科学的管理手段全方位开展管理工作。在线路损耗指标管控中应用了用电信息采集系统加强了管理的智能化、信息化。用电信息采集系统是一种通过现代化数字通信技术、计算机软硬件等高科技技术通过无线传输将现场设备的用电数据分类采集、归纳处理的系统。能够实现对电力线路、设备现场用电信息实时自动传送、用电异常检测、用电分析和管理等功能,为提高供电企业的营销生产管理水平提供了技术支持。对变电站、台区、用电客户加装用电信息采集终端,通过交互的数据分析实现对线损的异常检测、分析,与调度自动化系统、营销MIS管理系统、生产PMS等系统的有机结合,确定线损升降的主要原因,采取相应的降损技术和管理措施,通过细化环节、过程控制和严格考核,大大的提高了线损管理的实时性及全面性。用电信息采集系统可以为营销生产管理提供可靠决策依据和管理手段,同时能够适应未来生产管理和经营管理的发展要求以及将来电力商业化运营的要求。目前我公司运行用电信息采集终端设备15168套台,已实现辖内所有变电站、台区、用户的全覆盖、全采集。此项工作开展三年以来,公司综合线损下降5.61个百分点,直接经济收益八千多万元；计量设备及变压器类故障事件平均每年减少60余次；其中2014年用电信息采集系统监测及时发现2起35kv线路失压事件、3起l0kv用户窃电事件,为公司追回了20余万元的电费损失。基于用电信息采集系统的线损管理应用符合公司关于智能电网的发展要求,促进了传统人工式管理的转变。既为公司经济利益提供了更有力的保障,又为公司营销生产智能化管理建设提供一个有力支撑。本文以国网临清供电公司为例,首先分析了供电企业线损管理现状,并简单介绍了线损管理中应用用电信息采集系统的实时监测作用。再者简要的描述了临清公司在线路损耗指标管理方面应用用电信息采集系统的相关部门设置分工及相关流程设计,其中对重要流程设计中的关键环节及创新环节进行了详细的解释；对应用中的线损指标,绩效考核部门设置、分工及指标进行了介绍。最后对临清公司线损分析指标报表及应用此系统后发生的部分有代表性实例进行了详细的描述；介绍了用电信息采集系统的应用对临清市供电公司产生的企业效益及对未来发展的展望。
[Abstract]:In the power supply enterprise transmission, substation, power distribution, electric and other aspects, a line loss management is the most important index for which the technology and management of power supply enterprise production control is mainly reflected in the network planning, marketing, and other aspects of the comprehensive level. But its management style has been compared to a passive. During a period of large amounts of data can be aggregated to form statements behind the analysis of the problem of poor real-time, can detect the defects in line loss management. With the implementation of the national Power Grid Corp, a series of building "a strong three excellent" modern enterprise goal, especially for the power supply enterprise intelligent management of grass-roots County, put forward higher requirements in recent years, China Linqing City power supply company in all aspects of production and marketing, intelligent, information-based development, with more scientific management methods to carry out a full range of online management. The road loss index is used in the control of power information collection system to strengthen the intelligent management information. Electricity information collection system is a modern digital communication technology, computer software and hardware technology through the wireless transmission device for electric data acquisition processing system class, induction can be achieved on the power. Line equipment, field power real-time information automatic transmission, electric anomaly detection, power analysis and management functions, which provides technical support for improving the production and marketing management level of power supply enterprise. The substation, Taiwan area, electricity customers to install electricity information acquisition terminal, through interactive data analysis to achieve anomaly detection. Line loss analysis and dispatching automation system, MIS marketing management system, combined production PMS system, the main reason of rising or descending, take corresponding reduction and tube Rizos, through the refinement links, process control and strict examination, greatly improve the real-time and comprehensive line loss management. Electricity information acquisition system can provide a reliable basis for decision-making and management tools for marketing and production management, can adapt to the future development of production management and business management as well as the requirements of future power commercial operation at present our company operation. The electric energy data acquisition terminal equipment 15168 sets, has jurisdiction of all substations, the Taiwan area, the user's full coverage, full acquisition. Since the work carried out for three years, the company integrated line loss dropped 5.61 percentage points, direct economic benefits about eighty million yuan; more than 60 times of measurement equipment and transformer fault the average annual events decreased; in 2014 the electricity information collection system monitoring to detect 2 35kV line voltage loss event, 3 l0kV users of electric larceny, the company recovered 20 Million yuan in electricity loss. Application of line loss management of power information collection system with the company on the development of smart grid based on the requirements, promoted the transformation of traditional artificial management. Not only provides powerful guarantee for the economic interests of the company, and the company is the production and marketing of intelligent management of construction provides a strong support to this. China Linqing power supply company as an example, firstly analyzed the status quo of line loss management of power supply enterprise, and introduces the function of real-time monitoring of electricity information acquisition system used in line loss management. Furthermore, a brief description of the application by the relevant departments of electric information acquisition system set division and related process design company in Linqing line loss index management. The detailed explanation and innovation important tache in the process design; on line loss quota application, setting up performance department, division of labor And the indexes are introduced. Finally analysis index report and application of this system to the company after the loss Linqing some representative examples are described in detail; introduces the application of electric information acquisition system of Linqing City power supply company benefits and prospects for future development.
