摘要
为了解决低压台区电力线路线损难监测、难排查的问题,设计了一种电力线路线损监测系统。本系统可以对低压台区用户进行线损监测,分析并定位线损产生的位置,解决了目前线损监测排查困难的问题。通过台区进行划分,形成台区的树形结构,系统对每个树形结构所对应线路的总输入电量、分支线路输出电量及用户电量进行监测。考虑到实际节点的分散性和系统的经济性,各个测量点采用NB-IoT模块进行数据上传。线损监测时,通过上位机统一控制监测时间点,确保监测对象各点数据的时间统一性,有效减小了系统计算误差。通过分析树形结构以及计算各节点线损情况,定位发生线损超标的段点,提高了线损排查的效率。通过现场实验证实该系统符合设计要求,能够弥补目前电力行业线损监测漏洞,定位故障点,减小排查难度。
A power line loss monitoring system is designed to solve the problem of line loss monitoring and troubleshooting in low-voltage station area.This system can monitor the power consumption of the users in the low-voltage station area,locate the fault point,and solve the defects of the existing power line loss monitoring system.Firstly,the tree topology of the platform area is formed by dividing the platform area.Secondly,the system detects the total input power,the branch line output power and the user power of each node.Considering the wide distribution of the nodes and the system price,NB-IoT module is used for data uploading at each measurement point.The monitoring time is unified through the internet so that the data of each point can be monitored synchronously in real time,and this can reduce the calculating error of the system.By analyzing the tree structure and calculating the line loss rate of each node,the system can find the place where the line loss exceeds the standard.The experiment proves that the system can make the line loss monitoring of the current power industry smarter,and reduce the workload.
