This recommended practice specifies the PQDIF file format for the transfer of power quality data between instruments and computers. This includes raw, processed, simulated, proposed, specified, and calculated data. The transfer file format includes the power quality measurements as well as appropriate characterization parameters, such as sampling rate, resolution, calibration status, instrument identification, location, and other related data or characteristics. The recommended practice also provides guidelines for transferring power quality data.
IEEE Std 1159.3 provides the power quality industry with the specification for PQDIF, which is an open and accepted data format standard for the transfer of power quality data between instruments and computers. This transfer standard allows the processing and analysis of power quality measurements using multi-vendor and multi-device data. Wider acceptance of PQDIF as a power quality data transfer format will significantly add to the value of power quality monitoring and open new opportunities for the resolution, planning, and understanding of power quality activities. Being able to exchange data between software systems will allow other functions needed in a power quality monitoring campaign, including validation, trending, comparison, overlay, and more.
Revision Standard – Active. A file format suitable for exchanging power quality related measurement and simulation data in a vendor independent manner is defined in this recommended practice. The format is designed to represent all power quality phenomena identified in IEEE Std 1159-2009, IEEE Recommended Practice on Monitoring Electric Power Quality, other power related measurement data, and is extensible to other data types as well. The recommended file format utilizes a highly compressed storage scheme to help reduce disk space and transmission times. The utilization of Globally Unique Identifiers (GUID) to represent each element in the file permits the format to be extensible without the need for a central registration authority.
