Abstract

Abstract: During the “12th Five-Year” period, smart grid will enter the construction phase. Smart substation is a key part of the smart grid, and its operation status directly affects the safety and stability of the smart grid. Attentions therefore should be paid to all aspects of smart substation commissioning. An analysis was conducted on a protection action accident of a smart substation, which was caused by the defects of merging units of lines resulted from bus equipment faults. The dynamic simulation reconstructed accident and verified the correctness of treatment measures. Systematic testing was conducted on the related equipment, and some suggestions are proposed for future smart substation equipment commissioning test.

Key words: smart substation, accident analysis, dynamic simulation, protection, merging units
