The invention discloses a PQDIF (power quality data interchange format) communication uniformity detection method. The method includes the following steps: 1), setting a detection target of a PQDIF file, wherein the detection target is composed of different label items; 2), reading in the PQDIF file to be detected, and reading target label items and corresponding label values thereof of all channel records in a data source record of the to-be-detected file; 3), comparing whether a label value combination of the to-be-detected file and a standard label value combination meet communication format requirements or not. By the PQDIF communication uniformity detection method, PQDIF communication uniformity detection can be realized quickly and effectively, and intelligent recognition capability of a program is improved.
