Abstract: The data acquisition mainly refers to the collection of PQDIF （Power Quality Data Interchange Format）files. In this paper, an efficient and reliable data acquisition strategy is given through analyzing the source of PQDIF files and the data requirements of Power Quality Intelligent Information System. The collection strategy of PQDIF files includes both automatic collection and manual collection. The traditional multithreaded FTP technology is improved, thus the PQDIF files being created in a certain period time can be collected, which provides the Power Quality Intelligent Information System with reliable and realtime basis data sources.

Key words: PQDIF, FTP, data acquisition, power quality
