Abstract

Respective research have indicate power system´s stability will be influenced of single-phase reclosure sequence, however, little research has been performed that of three-phase reclosure. After analyzing model is constructed, index of branch stability degree, system stability degree and multi-swing stability based on branch transient potential energy method are defined to discuss the influence of three-phase reclosure sequence on system´s stabltiy. Simulation results in IEEE 3-generator 9-bus system indicate that system stability index can be enhanced by reclosing to normal terminal firstly.
