Abstract

The access of distributed power sources has changed the structure and operation of distribution networks, which makes protection methods currently no longer applicable, and the small probability of extreme disasters makes protections of distribution network face new challenges. In order to make the protection of active distribution network response to different fault types at the same time, a new method of active distribution network pilot protection based on the comparison of the projected and actual values of voltage fault components is proposed based on the analysis of the voltage fault component characteristics of the distribution network when a fault occurs. The method can effectively identify the faults in the zone under different fault types, and has the advantages of not being affected by unmeasurable branches, not being affected by distributed power penetration, and having strong ability to withstand transition resistance.
