Abstract: This paper fully considers the inherent characteristics of low rate and instability of carrier communication, combined with the engineering experience of several pilot projects, summarizes and analyzes the misunderstanding existing in the design of lean line loss scheme, and puts forward a kind of irregular and indefinite cycle reading method, which has achieved good results in the pilot project.
Key words: distribution transformer area; line loss lean management; power line carrier communication; cycle read

低压配变台区的供电线路多,走线复杂,分布面积广,用户用电行为多变且难以预测,线损动态变化范围大[1],长期以来基于用电信息采集系统的台区总表-用户电表模型仅能计算台区总线损,台区内部或局部更多的线损信息无法给出。(剩余3796字)
