窄带载波集抄方式常见问题解析与应对策略

Common Problem Analysis and Countermeasures of Narrowband Carrier Centralized Meter Reading Method

窄带载波集抄方式具有抗干扰能力强、连接户数多、施工方便等优点,但因施工工艺等原因在运行过程中存在抄表速度慢、重新组网、数据跳变等问题,直接影响抄表成功率的提升。以应用载波集抄方式较多的某县供电公司为例,介绍了窄带载波集抄方式的优点和常见问题,重点分析了问题产生原因,通过现场实践列出了清除冗余档案、消除跨相抄表和线路迂回、提升用电电压等针对性解决措施,总结了有效提高载波集抄方式抄表成功率的解决方案。

Narrowband carrier is advantaged by strong anti-interference capacity,a large number of connecting households and convenient construction. However, the improvement in meter reading success rate is directly affected by slow meter reading speed, network re-organization and data jump during the operation process due to construction technology and other reasons.Exampled by the power supply company of a county which frequently uses carrier centralized meter reading method,this paper introduces the advantages and common problems of narrowband carrier centralized meter reading method, emphatically analyzes the causes of problems,lists such targeted countermeasures as removing redundant archives, removing phase-crossing meter reading and line circuity and improving utilization voltage through field practice,and summarizes solutions for effectively improving the success rate of carrier centralized meter reading.
