چکیده
Increasing the power transfer capability and efficient utilization of available transmission lines, improving the power system controllability and stability, power oscillation damping and voltage compensation make a great interest in FACTS devices in recent decades. On the other hand, the presence of these devices results in new issues in the field of power system protection. Shunt compensators are one type of FACTS devices which their effects on protection system are studied in few papers. Since there is not a robust method in the few studies which are published about the protection of shunt compensated lines, it seems necessary to find a new method in this topic. Thus, the present paper proposes a new communication aided protection scheme which uses the available signals in commercial relays. The performance of this scheme is evaluated using PSCAD/EMTDC software and presented in this paper. The simulation results reveal that this scheme has appropriate immunity respect to fault and system condition and its performance is better than the conventional pilot schemes.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
