Based on the application of the new generation intelligent substation YeTang, this paper briefly introduces the function of the WIPM-801 power quality monitoring device. Through the analysis of the measure point needs and configuration in YeTang substation, how to choose the merging unit and build the process level framework is put forward. WIPM-801 adopts independent process level framework and distributs VLAN on a special exchange board to transfer data. The key point focuses on framework of 110 kV high side and 10 kV low side. It is the first substation to introduce GOOSE to the power quality monitoring device, based on the combination of the way the substation works and the data from WIPM, we can analyze the complicate power quality problem. Finally, the generation of power index files and how the files transform to PQDIF are discussed, then the implementation plans of the transmission of the substation and the power monitoring station are given.
