Abstract

The influence of soft-clamp misoperation on the relay protections is analyzed according to its actual application situations in smart substations, the fundamental principle and specific strategy against the soft-clamp misoperation are proposed, the implementation of soft-clamp misoperation prevention on the background supervisory control platform is introduced based on an actual smart substation project, and the expression and auto-generation of anti-misoperation logic for soft clamps are discussed.
