“…Resistive type SFCL can improve the transient stability of the power system by suppressing the level of fault currents in a quick and efficient manner [5,[69][70][71][72][73][74][75][76][77][78][79]. A very simple structure of resistive SFCL is shown in Figure 5 consisting of nth units of stabilizing and superconducting resistances in parallel [5].…”

Power systems are becoming more and more complex in nature due to the integration of several power electronic devices. Protection of such systems and augmentation of reliability as well as stability highly depend on limiting the fault currents. Several fault current limiters (FCLs) have been applied in power systems as they provide rapid and efficient fault current limitation. This paper presents a comprehensive literature review of the application of different types of FCLs in power systems. Applications of superconducting and non-superconducting FCLs are categorized as: (1) application in generation, transmission and distribution networks; (2) application in alternating current (AC)/direct current (DC) systems; (3) application in renewable energy resources integration; (4) application in distributed generation (DG); and (5) application for reliability, stability and fault ride through capability enhancement. Modeling, impact and control strategies of several FCLs in power systems are presented with practical implementation cases in different countries. Recommendations are provided to improve the performance of the FCLs in power systems with modification of its structures, optimal placement and proper control design. This review paper will be a good foundation for researchers working in power system stability issues and for industry to implement the ongoing research advancement in real systems.

“…In order to improve the ability of safe and stable operation for the power grid, many countries suggest that wind generators need low voltage ride through (LVRT) [2], which is the ability that when the voltage of the wind generator drops, caused by the grid fault or disturbance, the wind generator can operate in a grid‐connection state continuously [3]. For enhancing the LVRT of wind generators, the simulation study is becoming the key technology for wind power generation gradually.…”

“…The first group of LVRT approaches uses external passive and active equipments and hardware. Some literatures use passive elements such as crowbar, fault current limiter, and series damping resistor for LVRT improvement . A number of related papers use supercapacitor energy storage system, superconducting fault current limiter with magnetic energy storage device, flexible ac transmission systems, new different types of current limiters, and series converter located between the stator and grid .…”

Summary This paper analytically deals with the transient behavior evaluation and crowbar hardware design for the low voltage ride‐through (LVRT) capability enhancement in doubly fed induction generator (DFIG)‐based wind turbines (WTs). The paper indeed answers the following question analytically. “What are the main criteria for choosing the crowbar resistance?” It is shown that the value of the crowbar resistance affects both the peak values and oscillations of the DFIG transient response. Therefore, the paper first analytically investigates the rotor dynamics with the crowbar hardware during the voltage dip, and then develops analytical expressions for the crowbar resistance design to meet the LVRT requirement. It is shown that selection of the crowbar resistance higher than the maximum value may deteriorate the DFIG LVRT performance. Next, contribution of the DFIG to the fault current by using the crowbar is analytically studied. Then, the impact of crowbar resistance on the damping of the DFIG transient oscillations is examined by the modal analysis and phase plots of the stator flux. At the end, the concept of rotor active impedance is introduced, the LVRT capability of the DFIG is evaluated, and the DFIG transient responses under different crowbar resistances are investigated and compared.
