配电台区在线线损分级管理和智能异常分析设计

The hierarchical management and intelligent abnormal analysis of the distribution area on-line line loss

用电信息采集系统根据配变和用户用电数据实时计算配电台区在线线损率。提出根据台区用电负荷特征分类管理,有针对性地开展降损工作;根据在线线损的优劣进行分级管理,监视各个级别的台区在线线损每日变化情况,对波动超限的台区及时报警提示;搜集台区线损异常处理案例,建立典型案例库,以案例库为依据,设计台区线损异常智能诊断工具,指导现场检查处理。通过开发台区线损分析和分级管理软件,提高配电台区线损管理工作效率,促进电力营销业务精益化管理。

The low-voltage on-line line loss rate of the distribution unit-area can be computed through the power user energy data acquire system in real time,according to the distribution transformer and power consumption data.In this paper,we present a classified management method on the basis of the transformer area power consumption features and thus some targeted measures are developed on the line loss reduction.Hierarchical management was adopted to monitor the daily change of transformer area on-line line loss at different levels and can be timely alarmed when the range of fluctuation exceeds its limit,according to the evaluation of on-line line loss.We establish a case base by collecting the abnormal area line loss typical ground improvement case.We design intelligent diagnostic tools of area line loss on the basis of the cases database,to guide the on-site check and treatment.In this paper,we develop the line loss analysis and hierarchical management software to improve the line loss of the distribution unit-area management work efficiency and promote the lean management of power marketing
