【摘要】：随着电力能源的广泛应用和日渐紧缺,电力企业把减低损耗当做一种战略目标,希望通过降低损耗来提高经济效益。一直以来通过线损分压、等管理办法来进行理论线损计算,下达线损指标,进而用完成指标情况,进行奖惩来进行线损管理是电力部门降损节能的主要管理手段。但农村低压理论线损计算的计算结果和事迹统计线损的差值较大,原因还是在计算过程中用了各种假设,比如假设节点的电压相同等,最后计算结果也没有了参考价值,达不到对降损节能管理的要求。面对这种情况,县级供电公司急需一种能满足工作要求的理论线损计算方法和软件。近几年来,随着配电网系统的迅速发展,配电网络结构更加趋于复杂化,为配电网理论线损计算增加了难度;配电网自动化系统逐步应用,加强配电网的监控,各种数据采集变得容易,为配电网理论线损计算提供丰富的运行数据资料,正是由于以上两个方面,需要研究新的更加适合于目前配电网实际情况的理论线损计算系统。由于发电量和用电量年年增加,即使平均线损率能减少1个百分点,它的经济效益也是十分可观的。随着计算机硬件和软件技术、图形技术、网络通讯技术和计量手段的发展,让农村电网线损计算的精确变得可能实现。本系统通过现代化的技术对10Kv及以下电压等级的理论线损进行精确的计算,然后提供低压线路的降损节能方案,这对电力系统的降损节能非常重要。研究低压线损管理目的在于用日常工作中采集的数据信息,为10KV及其以下的低压线损每月提供可靠的动态考核凭证,提高县级供电公司低压线损的管理水平。本文对供电公司理论线损计算系统进行了详细的设计和实现,通过运用计算机网络技术和现在数据通信技术,结合现有的计算机设备资源,建立起统一的数据管理和应用的平台。根据供电公司所在地区的基本情况来进行定制化的开发和实现,在供电公司理论线损计算系统的设计过程中集成当前电网理论线损计算、统计、分析与一身,并结合当前的数据挖掘方法来对所有收集到的数据信息进行综合的分析,为供电公司领导的决策提供数据支持。
[Abstract]:With the wide application and increasing shortage of power energy, power enterprises take reducing loss as a strategic goal, hoping to improve economic efficiency by reducing loss.Line loss management is the main management method to reduce losses and save energy through line loss distribution, line loss calculation, line loss index, and reward and punishment for line loss management by means of line loss partial pressure and line loss management.However, the difference between the calculated results of the theoretical line loss of rural low-voltage theory and the statistical line loss of the deeds is quite large, because various assumptions are used in the calculation process, such as the assumption that the voltage of the node is the same, and the final calculation result has no reference value.Failure to meet the requirements of loss reduction and energy saving management.Faced with this situation, county-level power supply companies urgently need a theoretical line loss calculation method and software that can meet the work requirements.In recent years, with the rapid development of distribution network system, the distribution network structure becomes more complicated, which makes it more difficult to calculate the theoretical line loss of distribution network.All kinds of data acquisition become easy, which provides abundant operation data for theoretical line loss calculation of distribution network. Because of the above two aspects, it is necessary to study a new theoretical line loss calculation system which is more suitable for the actual situation of distribution network at present.Because of the annual increase in power generation and power consumption, even if the average line loss rate can be reduced by 1 percentage point, its economic benefits will be considerable.With the development of computer hardware and software technology, graphics technology, network communication technology and measurement means, it is possible to realize the accuracy of line loss calculation in rural power network.The system calculates the theoretical line loss of 10Kv and the voltage level below by modern technology, and then provides the energy saving scheme of the low voltage line, which is very important for the power system to reduce the loss and save energy.The purpose of studying low voltage line loss management is to use the data information collected in daily work to provide reliable dynamic check certificate for low voltage line loss under 10KV and below, and to improve the management level of low voltage line loss in county power supply company.This paper has carried on the detailed design and the realization to the power supply company theory line loss calculation system, through the use of the computer network technology and the present data communication technology, unifies the existing computer equipment resources,Establish a unified data management and application platform.According to the basic situation of the region where the power supply company is located, the development and realization of customization are carried out. In the design process of the theoretical line loss calculation system of the power supply company, the current power network theoretical line loss calculation, statistics, analysis and integration are integrated.Combined with the current data mining method, all the collected data information is analyzed synthetically to provide data support for the power supply company leader's decision.
