Abstract :

The only way to ensure a protective relay will perform as expected is to test it under realistic power system conditions. This generally means that the relay should be subjected to testing with transient data that occurs during real network conditions at the time of an event or fault. Such transient data can be generated from commercially available network simulation programs or re–playing fault recorded files (Disturbance recorder files). Many such programs are available today such as the ATP, EMTP, PSCAD/EMTDC and others. In each of these tools, its power system program generates the transient data in IEEE COMTRADE FORMAT. The author proposes how new techniques allow these COMTRADE files to be modeled in detail and easily simulate various fault scenarios and system conditions such as power swing, SSRC. The paper will provide a concept for protection efficacy and evaluation through advanced relay testing with help of Transient data.
