“…Tidak hanya pembangunan pembangkit listrik EBT yang terus harus digalakan, namun integrasi pembangkit listrik EBT ke dalam jaringan juga perlu ditingkatan karena memiliki beberapa kelebihan antara lain dapat mengurangi polusi udara, meningkatkan kualitas daya, mengurangi rugi-rugi daya pada jaringan dan memperbaiki profil tegangan [3]. Pembangunan pembangkit listrik EBT dekat dengan konsumen juga dapat mengurangi biaya pembangunan jaringan listrik [4]. Namun integrasi pembangkit listrik EBT ke dalam jaringan listrik juga memiliki kelemahan, yaitu dapat meningkatkan nilai arus gangguan diluar kapasitas peralatan proteksi yang sudah terpasang disamping itu stabilitas sistem dan kualitas tegangan juga akan ikut terganggu [5].…”

ABSTRAK Integrasi pembangkit listrik energi baru terbarukan ke jaringan listrik yang sudah ada dapat menyebabkan kenaikan arus gangguan, mengakibatkan peralatan proteksi yang ada tidak mampu untuk menangulanginya. Hal ini tentunya dapat menyebabkan kerusakan peralatan-peralatan listrik yang dilewati arus gangguan tersebut dan dapat mengakibatkan kegagalan dalam sistem penyaluran daya listrik. Pada penelitian ini dilakukan studi penggunaan peralatan superconducting fault current limiter/SFCL untuk membatasi arus gangguan yang timbul pada jaringan tenaga listrik. Dengan cara memanfaatkan impedansi yang dimiliki oleh SFCL untuk menggerakan mechanical switch (fast switch) sehingga arus gangguan akan melewati current limiting reactor yang terhubung paralel dengan superconductor yang dapat bekerja kurang dari setengah siklus setelah terjadinya ganggun. Pengujian sistem dilakukan dengan beberapa skenario yaitu: 1. sistem tanpa integrasi pembangkit listrik energi baru terbarukan; 2. sistem dengan integrasi pembangkit listrik energi baru terbarukan; 3. sistem dengan integrasi pembangkit listrik energi baru terbarukan dan superconducting fault current limiter. Hasil pengujian skenario 3 menunjukan adanya penurunan arus gangguan yang semula sebesar I = 1,007 kA menjadi I = 0,278 kA dan nilai tegangan sistem yang semula turun sebesar Vrms = 0,856 pu naik menjadi Vrms = 0,96 pu. ABSTRACT The integration of new and renewable energy power plants into existing power grids can cause an increase in fault currents, rendering existing protective equipment unable to cope. This of course can result in damage to electrical equipment through which the disturbance current passes and can result in failure in the electrical power distribution system. This research will conduct a study on the use of superconducting fault current limiter equipment to limit the fault currents that appear in the power grid, by utilizing a very high impedance to drive the mechanical switch (fast switch) so that the fault current will pass through the current limiting reactor which is connected parallel to the superconductor. which can work for less than half a cycle after the disturbance. System testing is carried out with several scenarios, namely: 1. systems without integration of new renewable energy power plants, 2. systems with integration of new renewable energy power plants, 3. systems with integration of new renewable energy power plants and superconducting fault current limiter. The test results of scenario 3 showed a decrease in the fault current by the original I = 1,007 kA to I = 0.278 kA and the value of the system voltage that originally decreased by Vrms = 0.856 pu rose to Vrms = 0.96 pu

Magnetic shielding inductive fault current limiters with high temperature superconducting tapes are considered as emerging devices that provide technology for the advent of modern power grids. The development of such limiters requires magnetic iron cores and leads to several design challenges regarding the constitutive parts of the limiter, namely the primary and secondary windings. Preliminary tests in a laboratory scale prototype have been carried out considering an assembly designed for simplicity in which the optimization of the magnetic coupling between the primary and secondary was not the main focus. This work addresses the design configuration of an inductive current limiter prototype regarding the assembly of the primary and secondary windings in the core. The prototype is based on a closed magnetic core wound by a primary, built from a normal electric conductor, and a short-circuited secondary, built from first generation superconducting tape. Four different design configurations are considered. Through experimental tests, the performance of such prototype is discussed and compared, in terms of normal and fault operation regimes. The results show that all the configurations assure effective magnetic shielding at normal operation regime, however, at fault operation regime, there are differences among configurations.

“…The feasibility and advantages of SCFL have already been demonstrated (Paul et al 1997;Khan et al 2011;Kovalsky et al 2005;Juengst 2002). There are two main topologies (Pina et al 2010), according to the insertion method of HTS material in the line, either in series (resistive topology) or magnetically (inductive).…”

The urgent need to solve existing problems in the electric grid led to the emergence of the new Smart Grid (SG) concept. A smart grid is usually described as an electricity network that can intelligently integrate the actions of all players connected to it in order to efficiently deliver sustainable, economic and secure electricity supplies. Smart grids should be flexible, accessible, reliable and economic, bringing great new challenges into grid management. In order to implement this concept it is necessary to consider the operation of several new devices in the electrical grid. A class of these potential devices is Superconducting Magnetic Energy Storage (SMES) that present, among other features, very fast response times. SMES devices can play a key role in helping to overcome several grids' faults. In this paper it is described the possibility to integrate SMES into SG, and the advantages of this integration.
