【 摘 要 】

This paper analyzes the structure and principle of the merging unit. Considering the effect of merging unit device performance of metering device and electrical protection, determines the inspection items and technical indicators. Combined with the merging unit related performance detection technology and related standards and rules, the paper uses system integration technology and automatic control technology to studied synchronization method in a separate network and the operation of SV for IEEE1588. Merging unit field calibration device was developed with advantages of high quality, good performance, reliable, and the device was used for field testing at some intelligent substation merge cells, its validity was proved.
