“…He et al [85] proposed this type of FCL in an HVDC system and analyzed the coordination between the FCL and DCCB to find the best parameter combination of the FCL. A capacitor modified type was proposed in [86] and both fault current and low-voltage ride-through issue can be solved by applying this FCL into wind farms. In [87], a parallel branch with a fully controllable semiconductor switch and resistor were added in the inductor circuit, while the control strategy was applied to detect the fault and insert the r p , so as to use L d and r p to restrict both severe fault rising rate issue and peak current value.…”

Fast emerging fault current levels in high voltage direct current (HVDC) systems has always been a significant obstacle to building a safer and more reliable grid. Inductive fault current limiters (FCLs), compared with its resistive counterpart, are very effective in restricting the fault rising speed that causes major damage during the whole fault process. In this study, a comprehensive review of the methods used for building inductive type FCLs in HVDC systems is presented. The fault current characteristics of the modern HVDC system is discussed to obtain the basic requirements for the FCL. On the basis of different technological domains, various inductive-type FCL topologies and devices are well categorized and analyzed. After the overall discussion and comparison, representative works, as well as new progress and future prospects, are conveyed in detail. One may find the content of this study helpful as a detailed literature review or a practical technical guidance of this field.

“…Instead, among different types of WT technology, variable-speed wind turbines with doubly fed induction generators (VSWT-DFIGs) have the most significant global market share due to their remarkable advantages, including lower converter rating and adjustable control, lightweight, high efficiency, output strength, excellent speed control, and decoupled ability to control active and reactive power [16,17]. Additionally, full-scale power electronic converters are required for permanent magnet synchronous generators, whereas partial-scale power converters are required for DFIG-based systems [18].…”

According to the grid code specifications, low voltage ride-through (LVRT) is one of the key factors for grid-tied wind farms (WFs). Since fixed-speed wind turbines with squirrel cage induction generators (FSWT-SCIGs) require an adequate quantity of reactive power throughout the transient period, conventional WF consisting of SCIG do not typically have LVRT capabilities that may cause instability in the power system. However, variable-speed wind turbines with doubly fed induction generators (VSWT-DFIGs) have an adequate amount of LVRT enhancement competency, and the active and reactive power transmitted to the grid can also be controlled. Moreover, DFIG is quite expensive because of its partial rating (AC/DC/AC) converter than SCIG. Accordingly, combined installation of both WFs could be an effective solution. Hence, this paper illustrated a new rotor-side converter (RSC) control scheme, which played a significant role in ensuring the LVRT aptitude for a wide range of hybrid WF consisting of both FSWT-SCIGs and VSWT-DFIGs. What is more, the proposed RSC controller of DFIG was configured to deliver an ample quantity of reactive power to the SCIG during the fault state to make the overall system stable. Simulation analyses were performed for both proposed and traditional controllers of RSC of the DFIG in the PSCAD/EMTDC environment to observe the proposed controller response. Overall, the presented control scheme could guarantee the LVRT aptitude of large-scale SCIG.

“…The main goal of FCLs is to lower the fault current to a level that the circuit breaker can conveniently and safely clear [11]. The utilization of FCLs in power system has not only been to suppress fault currents but has also been to enable voltage ride-through capabilities of wind farm doubly-fed induction generators [12], [13], enhance transient stability [14], eliminate voltage sags [15], improve power quality, limit inrush current in transformers [14] and increase the power transfer capability of the power system [16]. Various types of FCLs have been developed [17]; the most common being the superconducting fault current limiters (SFCLs), solidstate fault current limiters (SSFCL) and saturated core fault current limiters (SCFCL) [18].…”

The electrical distribution network is undergoing tremendous modifications with the introduction of distributed generation technologies which have led to an increase in fault current levels in the distribution network. Fault current limiters have been developed as a promising technology to limit fault current levels in power systems. Though, quite a number of fault current limiters have been developed; the most common are the superconducting fault current limiters, solid-state fault current limiters, and saturated core fault current limiters. These fault current limiters present potential fault current limiting solutions in power systems. Nevertheless, they encounter various challenges hindering their deployment and commercialization. This research aimed at designing a bridge-type nonsuperconducting fault current limiter with a novel topology for distribution network applications. The proposed bridge-type nonsuperconducting fault current limiter was designed and simulated using PSCAD/EMTDC. Simulation results showed the effectiveness of the proposed design in fault current limiting, voltage sag compensation during fault conditions, and its ability not to affect the load voltage and current during normal conditions as well as in suppressing the source powers during fault conditions. Simulation results also showed very minimal power loss by the fault current limiter during normal conditions.
