“…Many references report the short-circuit current behavior for converter-based low-voltage systems [6,7,[18][19][20][21][22][23][24], the behavior of insulated-gate bipolar transistors (IGBTs) in fault conditions [25,26], the protection techniques for low-voltage (high-voltage) DC distribution systems [6,[20][21][22][23][24]27], and DC compact systems (nodes) [6,7]. However, the dynamic performance of the electrical protection system in DC compact systems with solid state circuit breakers (SSCBs), hybrid circuit breakers (HCBs), and protective relays, especially during operation, has not been assessed in any depth.…”

This paper describes a multiterminal DC compact node consisting of voltage-source converters and DC-DC converters as a promising arrangement to feed electric vehicle (EV) charging stations with renewable power sources.This research analyzed the behavior of the node currents under DC faults, and more specifically their natural response, which can produce challenging electrical protection requirements. An electrical protection system was thus designed based on the use of protective devices that included protective relays, solid state circuit breakers and hybrid circuit breakers. These protective devices monitor local readings to detect and isolate DC faults as quickly as possible. This highlighted the fact that there are devices, available on the market, that comply with the fast response requirement to prevent damage or destruction of the converters and filter capacitors of the node.

“…DC distribution protection system is divided into three protection levels, namely, component level, device level, and system level. The researches of short circuit protection of component and device, such as the IGBT and the converter, have been addressed in many publications [17][18][19][20]. Hence, the protection presented in this paper is primarily focused on system level.…”

DC distribution system has advantages of high power quality, large transmission capacity, high reliability, simple structure, economy and low energy consumption, and so forth. It has been a key part of smart grid nowadays. However, the development of DC distribution system is constrained by the lack of operational experience in DC system, the small interrupting capacity of DC circuit breaker (CB), and the lack of protection schemes for system itself. In this paper, protection for DC distribution system with distributed generator (DG) is fully investigated and verified. Firstly, the electromagnetic transient model of DC distribution system with DG is presented. Simulation based on the electromagnetic transient model is carried out. Both the step response and the steady-state performance verify the accuracy of the model. Then the fault characteristic mechanism is analyzed, and the protection principles and scheme are investigated in detail, including voltage mutation principle as protection starting component, differential current protection principle for DC bus, and two-section current protection for distribution lines. Finally, transient responses with protection scheme are analyzed during faults. The results present that the protection principles and scheme are feasible for DC distribution system with DG.

“…The topics of shortcircuit protection of the inverter and the IGBT behavior in a short circuit have been addressed in many publications [4], [5], [6], [7], [8], [9], [10], [11]. Typically, the protection is based on short-circuit detection and converter shutdown (trip) in a short circuit.…”

The short-circuit protection of a low-power converter-fed low-voltage DC distribution network is investigated. In a public distribution network, the short-circuit protection is implemented by using fuses and circuit breakers, which may require a current that is over ten times the nominal currents of low-power DC/AC converter units to satisfy the recommendations. In the paper, the operation of the converter in a short circuit is studied, and the control scheme for the short-circuit current control and the fault ride through (FRT) operation is proposed. The operation of the short-circuit control scheme is verified by measurements. To overcome the problem of high fault current injection, alternative short-circuit protection realizations that are based on a simple low-current compact circuit breaker (but are not approved in standards) are proposed and demonstrated by measurements.
