“…However, the presence of a current limiting reactor in an electric circuit will lead to a signi cant increase in the circuit breaker transient recovery voltage, which will also have a greater impact on switching overvoltage and temporary overvoltage. And current limiting reactors are very easy to saturate at high currents and lose their current limiting effect (Chen et al 2013).…”

Battery energy storage system has become an important link to maintain the stable operation of DC microgrid because of its flexible control and fast response speed. As the battery storage system generally does not have fault current control capability, when a fault occurs between the poles of the system, the battery storage system will provide a great short-circuit current to the fault point, which will cause a great danger to the system operation and equipment safety. At this stage, current-limiting reactors or fault current limiters are generally added to the ports of the energy storage system to reduce the fault current, which has the disadvantage of limited current-limiting effect or high cost and large area, so it is not suitable for wide application in DC microgrid. This paper proposes a fault current control method for DC microgrid battery storage system, which enables the battery storage system to be connected to DC microgrid through Buck DC/DC by increasing the rated voltage of the battery stack.The control mode of the battery storage system is power control mode when the DC microgrid is running on grid, and it will be changed to voltage control mode when the DC microgrid is running off-grid. In case of inter-pole fault, the Buck DC/DC of the battery storage system is controlled to operate with reduced voltage to achieve fault current limit. This scheme does not affect the normal operation of the system, and can quickly limit the peak short-circuit current without adding additional equipment, making the short-circuit current flexible and controllable. Therefore, this scheme has good fault current limiting capability and greatly reduces the technical requirements of DC microgrid for protection. Finally, this paper verifies the feasibility of the proposed scheme and its control strategy through PSCAD/EMTDC modeling simulation.

Summary The fault current level in distribution systems has increased in the last years mainly due to the energy consumption is in the limit of the production capacity and also the insertion of distributed generation, since the short circuits happen very closer to the generators now. In addition to this, most of the power substations were designed decades ago, so their equipment is overcome, and they may be damaged in a fault occurrence. To effectively protect the settled equipment or to avoid high investment costs in replacing them, one possible solution is to install a solid‐state fault current limiter (SSFCL), which may reduce the fault current to a value under the supported level. In this context, this work proposes the development of two kinds of SSFCLs: series‐switched reactor and resonant circuit. These devices were designed and compared experimentally in bench prototypes. The measurements showed that both topologies could reduce the fault current from 600 APEAK to 75 APEAK. Both SSFCL‐tested configurations were implemented using silicon controlled rectifier or insulated gate bipolar transistor. The results present the comparison between them, showing the impact in the first semi‐cycle current profile, depending on the type of semiconductor switch adopted. This article also proposes a fault detection algorithm evaluated through digital implementation in a microcontroller. The algorithm detects the fault by the instantaneous current value and its derivative, using a control strategy that avoids false detection due to measurement noises. The theoretical analysis and results are useful contributions to support the SSFCL topology choice regarding its application.

“…However, high price, power losses, continuous current after fault current flow limitation, and harmonic distortion are some of the main problems of typical FCLs. Since the 1970s, several types of FCLs have been investigated such as fuses with fault-current limitation, series current limiting reactors [4], series transformers [5], superconducting fault current limiters (SCFCL) [6][7][8], solid-state FCLs (SSFCL) [9][10][11][12][13], and fault current limiting circuit breakers (FCLCB). In the recent years, researchers have focused on the SSFCLs and FCLCBs, such as: Purely resistive FCL [14], hybrid-resistive FCL [15], saturable core FCL [16], IGBTs controlled series reactor FCL [17], solid-state FCLCB (SSFCL-CB) [18], and bridge type FCL [19].…”

The protection of sensitive loads against voltage drop is a concern for the power system. A fast fault current limiter and circuit breaker can be a solution for rapid voltage recovery of sensitive loads. This paper proposes a compound type of current limiter and circuit breaker (CLCB) which can limit fault current and fast break to adjust voltage sags at the protected buses. In addition, it can act as a circuit breaker to open the faulty line. The proposed CLCB is based on a series L-C resonance, which contains a resonant transformer and a series capacitor bank. Moreover, the CLCB includes two anti-parallel power electronic switches (a diode and an IGBT) connected in series with bus couplers. In order to perform an analysis of CLCB performance, the proposed structure was simulated using MATLAB. In addition, an experimental prototype was built, tested, and the experimental results were reported. Comparisons show that experimental results were in fair agreement with the simulation results and confirm CLCB’s ability to act as a fault current limiter and a circuit breaker.
