ABSTRACT : The working principle and function of the phase-shifting transformer is presented briefly. And the site selection of the phase-shifting transformer is researched. This paper presents the index on reflecting the effect of regulation and the parameters on reflecting stability of the system. Also the method on site selection of the phase-shifting transformer is put forward. Finally the analysis result of a nine nodes example shows that with the presented index and method of site selection the installation position of phase-shifter can be effectively determined.
