Abstract

A method is presented for reproducing in the laboratory actual faults that have occurred in the field and generating worst-case-fault waveshapes for the actual power lines being protected. Digitally reproducing faults or system disturbances that caused undesired or unexplained results in the protection scheme is the key to the method. The faults can then be replayed through amplifiers and applied to the control and protection devices. Changes to settings or logic schemes can be implemented, and field data can be applied to the protection system located in the laboratory. The tested equipment can then be installed in the operating system with a high degree of confidence.<>
