چکیده: امروزه به دلیل افزایش قیمت منابع انرژی فسیلی، استفاده از تولیدات پراکنده که اغلب از انرژی­های نو استفاده می­کنند، در حال افزایش است. با نصب این واحدها در شبکه­های توزیع، سطح جریان اتصال کوتاه شبکه افزایش می­یابد؛ که این امر منجر به برهم­خوردن هماهنگی بین رله­های جریان زیاد موجود در سیستم و همچنین ایجاد جریان­های خطای بالاتر از قدرت قطع­کنندگی تجهیزات حفاظتی می­شود. در این مقاله از محدودس...

Concerning the development of a micro-grid integrated with multiple intermittent renewable energy resources, one of the main issues is related to the improvement of its robustness against short-circuit faults. In a sense, the superconducting fault current limiter (SFCL) can be regarded as a feasible approach to enhance the transient performance of a micro-grid under fault conditions. In this pa...

Günümüzde, nüfus artışı, yerleşim yerlerinin ve endüstriyel alanların genişlemesi teknolojinin gelişmesiyle birlikte elektrik tüketiminde önemli bir artış görülmektedir. Buna paralel olarak üretim kapasitelerinin de artması ile güç sistemlerinde çeşitli sebeplerle meydana gelen arızaların sebep olduğu yüksek akım seviyeleri, sistemdeki elemanlar için tehlikeli durumlar oluşturmaktadır. Arıza ak...

In the past few years there has been a significant rise in the short-circuit current levels in transmission and distribution networks, it due to the increasing demands on power and the addition of sources of distributed generations. It leads to the need of integration of novel protection systems such as the superconducting fault current limiters (SFCLs), as the installation of these devices int...

The stability related issues may occur in a power system due to disturbances generating or loading conditions, especially the presence of distributed generation (DG) based on renewable energy resources (RERs). This paper proposes novel strategy for enhancement wind (WPGS) by using combination three devices, namely, stabilizer (PSS), resistive superconductor fault current limiter (R-SFCL) and st...

An approach for assignment of the optimal location and tap changer adjustment related to flux-lock type superconducting fault current limiters with tap changer (TC-FLSFCL) is used in this paper by debating the reduction of fault current flowing from each device and enhancement of reliability varying with customer type in a distribution network connected with distribution generation (DG). TC-FLS...

As the energy demand increases due to developing electric power industry, fault current becomes higher during time. A new approach is needed reduce a in distribution system, since currents influence other protective devices’ operation. To decrease current, superconducting limiter (SFCL) has been suggested. The SFCL no loss with effect on system because impedance only occurs However, can current...

In this paper, the fault current limiting (FCL) characteristics of a flux-coupled type superconducting limiter (SFCL) with parallel connection between two windings in DC system were analyzed. The SFCL was composed coils connected and element (SE), which series secondary coil. works systems similar to those AC systems. Before occurs, respective magnetic fluxes generated by offset each other, mai...
