【摘要】：线损率能够反映电力网运行状态的好坏、电网管理运营水平的高低。降低线损率是保障供电电能质量、建设绿色电网、实现节能降损的有效方法。目前管理损耗是线损率居高不下的主要影响因素,因此运用用电信息采集系统及时采集用户用电信息、实时监控用户用电状态和处理异常数据,对降损增效具有深远意义。用电信息采集系统具备发布电网信息、监控分布式能源、交互智能用电设备的信息等功能,实现在线监测和用户负荷、电量、电压等重要信息的实时采集。发挥用电信息采集系统挖掘大量数据信息的功能,并制订出有效的管理方案和技术措施,对线损进行有效的控制和管理,实现节能增效,使电能的经济指标达到较为先进水平。电力用户用电信息采集系统与线损分析平台的结合,可以充分反映供电企业管理水平,同时用电信息采集技术引进线损管理可以使电网信息化的问题得以解决,具有很强的可行性与实践性,决定了未来智能绿色电网环境中线损管理的发展动向。推动线损管理由结果管理向过程管理的转变,提高供电运行的效率和管理水平。本文主要介绍了基于用电信息采集系统的线损管理系统主要内容和基本概述,运用数据挖掘算法构建了基于用电信息采集和线损管理系统的软硬件平台,对于线路线损、台区线损、大用户线损的线损异常因素进行实时分析,按线损率高低筛选出线损异常的线路、台区或大用户,并对这些异常的因素进行分析、归纳。线损管理中用电信息采集系统数据采集的不准确或者不充分的因素存在,本文增加了采集终端设备,使其能够采集到足够的数据进行分析,从而实现用电信息采集与线损分析系统的实时监测。最后本文针对高损线路和高损台区综合治理两个方面进行应用案例分析。
[Abstract]:The line loss rate can reflect the running state of power network and the level of power network management and operation. Reducing line loss rate is an effective method to ensure the quality of power supply, build green power grid, and realize energy saving and loss reduction. At present, the management loss is the main influence factor of high line loss rate. Therefore, it is of great significance to use the power information acquisition system to collect the user's electricity information in time, to monitor the user's power consumption state and to deal with the abnormal data in real time, which is of great significance to reduce the loss and increase the efficiency. The power information collection system has the functions of publishing power network information, monitoring distributed energy sources, exchanging information of intelligent power equipment, and realizing on-line monitoring and real-time collection of important information such as user load, electricity quantity, voltage and so on. The power consumption information collection system has the function of mining a large amount of data information, working out effective management scheme and technical measures, effectively controlling and managing line loss, realizing energy saving and increasing efficiency, and making the economic index of electric energy reach more advanced level. The combination of power consumption information acquisition system and line loss analysis platform can fully reflect the management level of power supply enterprises. At the same time, the introduction of line loss management in power information collection technology can solve the problem of power network informatization. It has strong feasibility and practicability, which determines the development trend of line loss management in the environment of smart green grid in the future. Promote the change of line loss management from result management to process management, and improve the efficiency and management level of power supply operation. This paper mainly introduces the main contents and basic overview of the line loss management system based on the power information acquisition system, and constructs the hardware and software platform of the line loss management system based on the data mining algorithm. The abnormal factors of line loss in station area and large user are analyzed in real time. According to the line loss rate, the abnormal line, station area or large user are screened out, and these abnormal factors are analyzed and summarized. In line loss management, there are some inaccuracies or inadequacies in the data collection of power consumption information acquisition system. In this paper, the acquisition terminal equipment is added to make it possible to collect enough data for analysis. Thus the real-time monitoring of power information acquisition and line loss analysis system is realized. Finally, this paper analyzes the application cases of high-loss line and high-damage platform area.
