“…These limiters need fault detectors. Several types of impedance limiters are classified by mechanical switch as follows [21]: i) Fault current limiter by using parallel barriers and resistant switch; ii) Fault current limiter based on method of arc deviation by using resistant rail; iii) Fault current limiter based on method of arc deviation by using element which deviates arc.…”

Increased generation capacity along with entrance of new power plants to the grid has caused increase in the level of short circuit in transmission grid substations. In this paper, methods for decreasing fault current used theoretically and practically are gathered briefly first. Then, short circuit level is studied in transmission substations at Azerbaijan regional electricity company region in 2014 to introduce practical methods to decrease fault current. Short circuit level of mentioned transmission grid is analyzed using DIgSILENT and appropriate methods are proposed to decrease fault current.Index Terms--Short circuit level, fault current limiter, Azerbaijan electricity grid, DIgSILENT.

“…In 1998, a hybrid current-limiting interrupting device (HCLID) was proposed by experts at the Technical University of Gdansk, Gdansk, Poland. The structure of the HCLID is simple: a mechanical contact, two diode and two thyristors, together with an L-C series-connected circuit [31,32]. As seen in Figure 11, the HCLID may inject a countercurrent into the main path to provide zero-crossing conditions.…”

Circuit breakers (CBs) are the main protection devices for both alternating current (AC) and direct current (DC) power systems, ranging from tens of watts up to megawatts. This paper reviews the current status for solid-state circuit breakers (SSCBs) as well as hybrid circuit breakers (HCBs) with semiconductor power devices. A few novel SSCB and HCB concepts are described in this paper, including advantage and limitation discussions of wide-band-gap (WBG) devices in basic SSCB/HCB configuration by simulation and 360 V/150 A experimental verifications. Novel SSCB/HCB configurations combining ultra-fast switching and high efficiency at normal operation are proposed. Different types of power devices are installed in these circuit breakers to achieve adequate performance. Challenges and future trends of semiconductor power devices in SSCB/HCB with different voltage/power levels and special performance requirements are clarified.

“…According to this principle, a hybrid circuit breaker based on high-speed switch (HSS) and parallel connected capacitor is designed to commutate the fault current, which has been introduced a lot before. [6][7][8][9] These breakers have independent branches to carry the rated current and break fault current. As the current is commutated into the capacitor in single-stage operation during the fault current breaking, the energy stored in inductance is absorbed by the capacitor within a very short time.…”

The DC hybrid circuit breaker based on high-speed switch (HSS) and parallel connected capacitor has been widely applied in the fault current breaking of DC system. However, when the current is commutated from HSS to the capacitor according to single-stage operation, the capacitor has to absorb a large amount of energy stored in the system inductance within very short time. Meanwhile, a high over-voltage rate of rise is especially prone to be produced between the contacts of HSS, which will lead to a failed breaking. As a result, a novel DC hybrid circuit breaker based on the two-stage operation is proposed and analyzed in this paper. By controlling the thyristors in the commutation branches, the fault current is fast commutated into the capacitor, which can not only realize the arcless open of HSS, but also decrease the over-voltage rate of rise significantly in comparison to the traditional single-stage operation. The simulation model of fault current breaking under different conditions in 10 kV medium voltage DC system is constructed. The simulated over-voltages of single-stage and two-stage operations in the case of fault current breaking are compared and analyzed. Finally, the fault current breaking test in the two-stage operation is investigated experimentally, which validates the feasibility and effectiveness of the simulation model well.
