“… The power circuit topology of the FCL introduced in [27,28] utilises three similar sets of the FCL in series with individual phases to limit the fault currents. This approach requires three single phase diode-bridge rectifiers, three SSs, three DC inductances, and three series R-L branches, which are connected in parallel with the diode-bridge rectifier to compensate the voltage sag caused during the fault.…”

Low voltage ride-through enhancement of DFIG-based wind turbine using DC link switchable resistive type fault current limiter Abstract Doubly-fed induction generator (DFIG)-based wind turbines utilise small-scale voltage sourced converters with a limited overcurrent withstand capability, which makes the DFIG-based wind turbines very vulnerable to grid faults. Often, modern DFIG systems employ a crowbar protection at the rotor circuit to protect the rotor side converter (RSC) during grid faults. This method converts the DFIG to a squirrel cage induction generator, which does not comply with the new grid codes. The recent grid codes need wind turbines to stay connected to the utility grid during and after power system faults, especially in high penetration level of wind power. Furthermore, the crowbar switch is expensive. This paper proposes a novel DC-link switchable resistive-type fault current limiter (SRFCL) to improve the LVRT capability of the DFIG. The proposed SRFCL is employed in the DC side of the RSC. The SRFCL solves crowbar protection activation problems and eliminates subsequent complications in the DFIG system. The proposed SRFCL does not have any significant impact on the overall performance of the DFIG during normal operation. Whenever the fault, whether symmetrical or asymmetrical, occurs, the SRFCL not only limits rotor over-currents but also prevents rotor speed acceleration and restricts high torque oscillations even during zero grid voltage, as recommended by some grid codes. To prove the effective operation of the SRFCL on the RSC fault current limitation, analytical analysis is performed in each switching interval. The proposed approach is compared with the crowbar-based protection method. Simulation studies are carried out in PSCAD/EMTDC software. In addition, a prototype is provided to demonstrate the main concept of the proposed approach. Simulation studies are carried out in PSCAD/EMTDC software.

Laburpena: Goi-tentsioko korronte zuzeneko (ingelesez, High Voltage Direct Current HVDC) garraio-sistemak gero eta garrantzitsuagoak dira sistema elektrikoan, onura ekonomiko eta teknikoak direla eta. Hala ere, akatsen bat gertatzen denean, korrontea eteteak oraindik ere erronka izaten jarraitzen du HVDC sareetan. Desiragarriak ez diren korronteak eteteko, korronte zuzeneko etengailuak erabil daitezke, baina horien gaitasuna mugatua da. Egoera hala izanik, akats-korronteen mugagailuak (ingelesez, Fault Current Limiter FCL) dira proposamenik egokiena akats-korronteak maneiagarriagoak diren balioetara txikitzeko; hartara, sistema elektrikoaren garraio-ahalmena handitu daiteke, ekipamendua aldatu beharrik gabe. Sarean aldez aurretik legokeen ekipamendua gai izango litzateke korronte berriak kudeatzeko eta sistema era eraginkorrean babesteko FCLen erabilpenaz. Artikulu honetan, FCL tresnen ezaugarri orokorrak eta sailkapena aurkezten dira. Ondoren, egoera solidoko FCLa erabili da maila anizkoitzeko bihurgailudun (ingelesez, Modular Multilevel Converter MMC) VSC-HVDC (ingelesez, Voltage Source Converter) sistema batean, eta horren jokaera azaltzen da simulazio bidez.Hitz gakoak: Goi-tentsioko korronte zuzena (HVDC), akats-korronteen mugagailua (FCL), korronte zuzeneko etengailua, maila anitzeko bihurgailua (MMC), egoera solidoa, supereroaleak.Abstract: High Voltage Direct Current (HVDC) transmission systems are playing an important role due to their economical and technical benefits in the countries where the electric grid is expanding fast. However, fault current interruption is still an unsolved challenge in these HVDC grids. In order to interrupt undesirable currents, DC circuit breakers can be used, but their capability is limited. Under that scenario, Fault Current Limiters (FCL) arise as a good approach in order to reduce fault currents to a more

Abstract-In this paper, a non-controlled fault current limiter (FCL) is proposed to improve fault ride through capability of doubly fed induction generator (DFIG)-based wind turbine. Cooperative operation of chopper circuit and the non-controlled FCL, which is located in rotor side of the DFIG, is studied. It is demonstrated that locating the proposed topology in the rotor side is effective from leakage coefficient point of view in limiting transient over currents rather than stator side. Furthermore, it is shown that, by obtaining optimum non-superconducting reactor value, rate of fault current change is limited to lower than maximum rate of current change in semiconductor switches of the DFIG's converters during fault. Design methodology of non-superconducting reactor value is investigated. Operation of the non-controlled FCL in the rotor side is compared to crowbar protection scheme and results will be discussed. PSCAD/EMTDC software is employed to simulate the proposed scheme and prove its effectiveness.Index Terms-doubly fed induction generator; fault ride through; leakage coefficient; non-controlled fault current limiter; non-superconducting reactor.
