基于132 kHz载波模块的双频点载波用电信息采集技术及应用

Dual Frequency Point Carrier Electrical Information Acquisition Technology and Application Based on 132 kHz Carrier Module

针对部分使用132 k Hz载波通信模块的智能电能表台区受负荷性质影响,通信环境恶化,台区采集稳定性差的问题,提出双频点技术,即在不改变原有载波频点情况下,并行高频点载波通信技术,分析该双频点技术关键和功能,可有效弥补低频点受干扰的盲点,通过在衡水市区多个不稳定台区推广应用分析,采集成功率均稳定在98.5%以上,说明该技术应用效果良好。

Because power distribution area of smart measures with 132 kV carrier communication module is affected by the load characteristics,communication condition is worse and power distribution is bad, this paper advances the dualfrequency point technology, which is the parallel high frequency carrier communication technology under the original carrier frequency, analyzes the key technology and function, this technology can make up the blind spot of low frequency point by interference, through application analysis of some unstability power distribution area of Hengshui region, it is considers that acquisition success rate is up to 98. 5 %, the application effect is well.
