Abstract: Due to the low efficiency of data processing and high export delay of intelligent measurement

equipment in substation engineering，the construction progress of substation engineering is slow. Therefore，the data batch export system of intelligent measurement equipment in substation engineering was designed. The information acquisition instrument was used to collect the data of intelligent measurement equipment in the substation project. On this basis，the collected data was transmitted to the data center remotely by using the SDH optical fiber ring network.The data center realized the data normalization processing by converting the data format. The K-means algorithm was used to cluster the normalized data，and the batch export algorithm was used to export the clustering results to Excel，it is easy to use by the production and management personnel in the substation project. The system test results show that the data processing and clustering time of the designed system is short，and the data of intelligent measurement equipment in substation engineering field can be exported in batches. The time delay of single data export is less than 120 ms，and the throughput is up to 8 264 after running for 40 s. The practical application effect is good.
