Research on Secondary Precision Detection Technology of Primary and Secondary Fusion Complete Equipment

配电网一二次融合成套设备工作中,由于一二次设备之间匹配和工作模式的不同,会影响二次精度检测的准确性。首先分析了一二次成套设备的结构和形式,然后针对一二次融合成套设备的二次精度检测关键技术进行深入分析研究,包括双路同步采样测量技术和微弱信号抗干扰测量技术,保证了一二次融合终端检测时,能够准确地测量微弱信号,多种模式的终端实现一体化检测和校准,也为一二次融合成套设备的入网检测及到货检测提供有效指导。

Because the difference of the matching and operation mode of the primary and secondary equipment will affect the accuracy of the secondary accuracy detection.This paper fi rst analyzes the structure and form of primary and secondary sets,and then deeply analyzes the key technologies of secondary precision detection of primary and secondary fusion sets,including two-way synchronous sampling measurement technology and weak signal anti-interference measurement technology.The study in this paper ensures that the weak signal can be measured accurately,the terminal realizes integrated detection and calibration,and also provides effective guidance for the network access detection and arrival detection of primary and secondary fusion equipment.
