Abstract

This paper discuss the influence of the reclosure time on the stability of electric power systems, establishes a mathematical model and derives the optimum condition of reclosure about transient and permanent faults using the energy function. Emulation calculations show that reclosing at optimal time will improve the stability margin, transmitted power and the transient stability greatly. It lays the foundation of reclosing time setting and the study of the optimal reclosure
