“…The three-phase version consists of three similar single-phase structures of the TCAR and they can independently operate in each phase of the network. A point that should especially be noted is that fewer components are required for the proposed TCAR as compared with other FCLs [13][14][15]. According to the simulation and experimental results, it has been proved that the proposed TCAR is effective for fault current breaking and restoring the PCC voltage to the acceptable level.…”

“…However, this FCL has a considerable power losses on the equipments, it is not cost effective due to its components, it needs costly cooling system and complicated control system. But the suggested TCAR has a simple structure, the power losses on its components are negligible and it has a simple control system [13][14][15]. Development of the proposed single-phase TCAR to three-phase TCAR is easy.…”

-Recently, various types of Solid State Fault Current Limiters (SSFCLs) have been proposed. These SSFCLs can improve the voltage quality, decrease the transmission losses, and also can enhance the distribution network stability but there are some practical problems with these FCLs. This paper proposes a modified FCL with focusing on the components optimization, efficiency improvement and reducing the cost. The suggested FCL uses a series AC reactor with controllable power electronic switches named Thyristor-Controlled AC Reactor (TCAR) which is connected in series with the feeder to limit the fault current and avoid fault current problems, which impairs overall distribution network reliability. The influence of TCAR on the fault current is analyzed using analytical, simulation and laboratory tests. The performance of the proposed TCAR in the simple distribution network is examined. The simulation and experimental results are in a good agreement with together and show the proper operation of the proposed TCAR during the normal and fault operation modes.

“…A number of methods of high-speed splitting between commercial power systems and nonutility generation facilities have been proposed to prevent shutdowns of critical loads and propagation of faults to distributed generators in the case of voltage sags caused by lightning strikes or other system faults [1][2][3][4][5]. For example, there are devices providing high-speed contact separation by utilizing electromagnetic repulsion in vacuum circuit breakers, devices that employ GTO and other semiconductor components, and hybrid designs that combine vacuum circuit breakers with semiconductor switches.…”

SUMMARYThis paper deals with a new detection method based on three-phase vector operation for voltage sag. The detection method is applicable to a protection system using a high-speed interruption system which protects distributed generators and critical loads in a customer's facility. The algorithm and merits of this method are explained in detail. The detection characteristics are then analyzed using the ATP (Alternative Transients Program) and are confirmed using a real-time digital simulator, and it is shown that the method is useful for detecting voltage sag.

“…As one of researching hotspots currently, DC fault current limiter is mainly achieved by the following three ways: superconductor, 8,9 power electronic devices 10,11 and saturable core. [12][13][14][15] Since the front two methods are both too expensive and complicated for actual implementation of fault current limiter (FCL) in HVDC area, our team applied saturable core theory and proposed a novel concept of DC system fault current limiter (DCSFCL) using permanent magnets (PM) and iron core to generate variable inductance to limit DC fault current at early stage.…”

Performance investigation on DCSFCL considering different magnetic materials

In order to protect high voltage direct current (HVDC) system from destructive consequences caused by fault current, a novel concept of HVDC system fault current limiter (DCSFCL) was proposed previously. Since DCSFCL is based on saturable core reactor theory, iron core becomes the key to the final performance of it. Therefore, three typical kinds of soft magnetic materials were chosen to find out their impact on performances of DCSFCL. Different characteristics of materials were compared and their theoretical deductions were carried out, too. In the meanwhile, 3D models applying those three materials were built separately and finite element analysis simulations were performed to compare these results and further verify the assumptions. It turns out that materials with large saturation flux density value Bs like silicon steel and short demagnetization time like ferrite might be the best choice for DCSFCL, which can be a future research direction of magnetic materials.
