IEEE St<strong>and</strong>ard Common Format for<br />
Transient Data Exchange<br />
(COMTRADE) for Power Systems<br />
4.1 Introduction<br />
The rapid evolution <strong>and</strong> implementation <strong>of</strong> digital devices for fault <strong>and</strong> transient record-<br />
ing <strong>and</strong> testing in the electric utility industry has generated the need for a st<strong>and</strong>ard<br />
format for the exchange <strong>of</strong> such data for use with various devices <strong>to</strong> enhance <strong>and</strong> au<strong>to</strong>-<br />
mate the analysis, testing, evaluation <strong>and</strong> simulation <strong>of</strong> the power system <strong>and</strong> related<br />
protection schemes during fault <strong>and</strong> disturbance conditions.<br />
The COMTRADE st<strong>and</strong>ard defines a common format for the data files <strong>and</strong> exchange<br />
medium needed for the interchange <strong>of</strong> various types <strong>of</strong> fault, test, or simulation data.<br />
The proliferation <strong>and</strong> implementation <strong>of</strong> digital devices for the acquisition, analysis,<br />
simulation <strong>and</strong> testing <strong>of</strong> power - system equipment has made available a pr<strong>of</strong>usion<br />
<strong>and</strong> variety <strong>of</strong> data that has not been readily available in the past. Since these data<br />
may come from a variety <strong>of</strong> sources, from different manufacturers using proprietary<br />
or other st<strong>and</strong>ard formats, a common format st<strong>and</strong>ard is necessary <strong>to</strong> facilitate the<br />
exchange <strong>of</strong> such data between devices with diverse applications but that have the<br />
