Summary:This paper proposes a refined Differential Current Protection Method (DCRM) to solve problems associated with malfunction or error in relay response caused by operation of FACTS devices. The FACTS devices of interest include STATCOM, SSSC and UPFC. Analytical models and methods are presented to analyze impacts of those compensation devices on the transmission system for these devices. A variety of faults cases are studied with the proposed methods and simulation results are provided as well.
