Abstract (sommario):

Since the development of Low Critical Temperature Superconducting (low-Tc) materials, various studies have been published regarding this experimental concept. Recently, researchers have focused on the design and application of high-Tc superconductor (high-Tc) materials to develop fault current limiting circuit breakers. The operation of this circuit requires large prospective/limited current ratios, especially in hazardous areas. In spite of this, several studies describing the Superconducting Fault Current Limiter (SFCL) containing members of the bismuth, mercury or yttrium family cuprate have already been described. However, none of these studies included samarium cuprates. Consequently, we have conducted a study of a small superconducting current limiter device based on SmBa2Cu3O7-d samples. The preliminary results indicated that samarium cuprates could be applied to build superconducting fault current limiter devices. In tests using a polycrystalline sample, the superconducting properties were retained without modifications to its stoichiometry. These results suggest the possibility of future investigations into SFCL devices based on these superconducting ceramics. Keywords: High-Tc, Sm-123, Device, Fault current limiter.

Abstract (sommario):

AbstractThis issue of MRS Bulletin provides an overview of the current status of research and development in the area of high-temperature superconductor (HTS) wires. High-temperature oxide superconductors, discovered in the late 1980s, are moving into the second generation of their development.The first generation relied on bismuth strontium calcium copper oxide, and the second generation is based on yttrium barium copper oxide, which has the potential to be less expensive and to perform better.The potential uses of HTS wires for electric power applications include underground transmission cables, oil-free transformers, superconducting magnetic-energy storage units, fault-current limiters, high-efficiency motors, and compact generators.Wires of 10–100 m in length can now be made, but material and processing issues must be solved before an optimized production scheme can be achieved.This issue covers a range of processing techniques using energetic beams, rolling, and laser and chemical methods to form wires with good superconducting properties.

Abstract (sommario):

Since the discovery of superconductors, research has shifted from simple metals to alloys and further to complex compounds. As the record of critical temperature gradually increases, more opportunities and challenges have emerged. The Bardeen-Cooper-Schrieffer theory failed to explain certain observations of unconventional superconductors. However, breakthroughs have been made on the new understanding of unconventional superconductors. This article will introduce various challenges to and opportunities for the application of unconventional superconductors, including the high-temperature superconducting fault-current limiter and the superconducting energy-storage system.

Abstract (sommario):

The application of high-temperature superconductor resistors (HTSC resistors) in ac electrical equipment and networks has been considered to protect them from fault currents and single-phase to earth faults. To improve the response speed and thermal withstand capability of HTSC fault current limiters the use of a stable overloaded regime in composite HTSC wires has been proposed. Basic circuits has been developed for the application of stabilized HTSC wires of low-ohmic value in protective resistors for ac networks that enables to increase the apparent resistance in the circuit by few orders of magnitude. The results are given of measurements of characteristics of first generation HTSC wires with high critical parameters in resistive state in a wide range of overcurrent. Prototype instantaneous current limiters with high thermal capability using the HTSC protective resistors have been manufactured and tested. The estimated values are given for the design parameters of the HTSC protective resistors applicable in electrical networks.

Abstract (sommario):

The influence of CuO nanoscale inclusions as the second component of the composites on the transport properties of superconducting polycrystals YBa2Cu3O7 was studied. Samples of YBa2Cu3O[Formula: see text] with different content of CuO nanoparticles were synthesized. The analysis of magnetic properties was carried out within the framework of the extended critical state model. It was found that the addition of 20[Formula: see text]wt.% CuO nanoparticles leads to an increase in the critical current density at [Formula: see text][Formula: see text]K. A further increase to 30[Formula: see text]wt.% reduces the critical current density. The results of the experimental studies of a switching superconducting fault current limiter in AC voltage networks based on high-temperature superconductors (HTSC) of the 2nd generation are given in this work. The testing equipment contains a series-connected HTSC module and a high-speed current switch with a break time of 9[Formula: see text]ms. The high efficiency of the samples made from the YBa2Cu3O[Formula: see text] + CuO nanocomposite material as an active element of a resistive current limiter is shown.

Abstract (sommario):

Short current limiting technology is a hot problem in power grid with short current increasing. Several short current limiting technologies are analyzed. And improved bridge-type superconductor current limiter which can limit instantaneous and steady short current is presented. Resistance-type, bridge-type and improved bridge-type superconductor current limiter are simulated. Scheme and parameters are proposed, based on which we develop a 10 kV high-temperature superconductor current limiter. In Aug.14th, short testing implements at Gaoxi 110 kV power station in Loudi bureau, Hunan Province. Later, the limiter runs in the power grid. In short testing, the limiter can prevent the short current from 3500 A (Vms) to 635 A(Vms). There is no saltation in wave. The superconductor current limiter has run six month and all indexes are well-balanced. All these can make a base for superconductor current limiter large-scale application.

Abstract (sommario):

Power systems under expansion suffer from escalating fault levels that impact equipment integrity, operational flexibility, and the overall security of the system. The fault current limiter (FCL) is one of approaches used by utilities to limit fault current levels and in Dubai Aluminum (DUBAL) series current limiting reactors are currently used. However, more effective (FCL) topologies are sought and, in this paper, a case study is proposed using resistive high temperature superconducting fault current limiters (HT-SFCLs). The application of HT-SCFLs is aimed here at reducing short-circuit currents, while at the same time enhancing the stability and security of the network. The study involves analysis of three-phase and single-line-to-ground faults, evaluation of the voltage levels and total harmonic distortion (THD) levels at busbars considering different fault scenarios, and demonstrates how the use of HT-SFCLs at various locations improves the plant performance. The ideal HT-SFCL model is adopted for this analysis since the aim is to look at the steady-state performance rather than the transient performance. Comparison with series reactor FCLs which are currently installed in the plant show better performance with the proposed HT-SFCL. Voltage profile values and total harmonic content were also compared with measurement data available at the plant.

Abstract (sommario):

As the application of low-voltage-direct-current system increases, fault analysis in the low-voltage-direct-current system has essential because the fault response has different from the conventional AC distribution system. Especially, the fault current by the discharge current of the capacitor in the low-voltage-direct-current distribution system has very large compared with the conventional AC distribution system. Therefore, this paper proposed the application of the superconducting fault current limiter for limiting the fault current on the low-voltage-direct-current system. As one of the protected methods against fault current, the superconducting fault current limiter which could quickly limit the fault current has been noticed as an attractive method. However, the protection relay may malfunction such as over current relay, selective protection relay due to limiting fault current by applying superconducting fault current limiter. Therefore, in this paper proposed a solution to malfunction problem of the protection relay using the voltage components of the high temperature superconductivity. This paper verified the effect of the proposed method through test modelling and PSCAD/EMTDC.

Abstract (sommario):

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

Abstract (sommario):

Taking a technology from the laboratory to industry is a long and resource-consuming process. Discovered more than a century ago, the phenomenon of superconductivity is testament to this process. Despite the promise of this technology, currently the only major use of superconductors outside the laboratory is in MRI machines. The advent of high-temperature superconductors in 1986 heralded a new dawn. Machines which do not require cooling with liquid helium are a very attractive target. A myriad range of different superconductors were rapidly discovered over the next decade. This process of discovery continues to this day with, most recently, a whole new class, the pnictides, being discovered in 2006. Many different usages have been identified, including in motors, generators, wind turbines, fault current limiters, and high-current low-loss cables. This Special Issue looks at some of the different factors which will help to realise these devices and thereby bring about a superconducting world

Abstract (sommario):

As the capacity of the power grid continues to expand, high-level fault currents might be caused during a contingency, and the problem of short-circuit current over-limitation is imminent. The high-temperature superconducting (HTS) fault current limiter (FCL) is an effective method to solve this problem. In this paper, a transient numerical model for the process of limiting current in the inductive FCL is proposed. The model is based on the coupling of multiphysics finite element simulation and a circuit model. The voltage source is used as input, which can simulate the macroscopic characteristics in the process of limiting current, such as the voltage and current waveforms, and can also simulate microscopic characteristics, such as temperature, magnetic field, and electrodynamic force distribution. The short-circuit experimental data of an air core inductive superconducting fault current limiter (SFCL) prototype was compared with the simulation results to verify the reliability of the simulation.

Abstract (sommario):

Abstract 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.

Abstract (sommario):

This paper analyzes the structure, the physical parameters and the working principle quantitatively of the single-phase DC-turned off High Temperature Superconducting Fault Current Limiter (SFCL) with Saturated Iron Core. On this basis, a dynamic system model is established and simulation to study the relationships among the various system electrical parameters. The simulation results and the actual waveforms collected from the sample machine were compared to verify the correctness of the model. And the simulation experiment shows that this kind of SFCL is available for current limitation.

Abstract (sommario):

A bridge type superconducting fault current limiter (SFCL) with simultaneous quench using two high-temperature superconducting (HTSC) elements and two coils was fabricated to analyze the fault current limiting characteristics. Before and after the fault occurrence, the current limiting operation and the voltage waveforms of each device were compared according to the change of the input voltage. We also analyzed flux linkages and instantaneous powers of the bridge type SFCL with simultaneous quench using flux-coupling composed of HTSC elements with different critical currents. During the fault period, the magnetization power area and the flux linkage’s operating range variation due to the magnetizing current were compared with each other.

Abstract (sommario):

In this paper, a bridge type superconducting fault current limiter (SFCL) with a single high-temperature superconducting (HTSC) element is proposed to allow fault current limiting operation in direct current (DC) conditions. First, the principle of operation of the bridge type SFCL with a single HTSC element using flux-coupling was presented. After the fault occurrence, the fault current limiting operation and voltage characteristics, the power load characteristics of each device, and the energy consumption of the two coils and the HTSC element were analyzed in the proposed SFCL. As a result, it is confirmed that in the case of the additive polarity winding, the power consumption and the energy consumption of the HTSC element were lower than those in the subtractive polarity winding, and the fault current limiting characteristics were excellent.
