Zero volt switching hybrid DC circuit breakers

Conference Record of the 2000 IEEE Industry Applications Conference. Thirty-Fifth IAS Annual Meeting and World Conference on Industrial Applications of Electrical Energy (Cat. No.00CH37129), 2002
DC distribution networks have the advantage of easy connection of generators of different frequency, fuel cells, and storage devices like batteries and flywheels to a grid and the advantage of a lower current load of the cables. Despite these advantages, often an AC distribution network is chosen because of the lack of reliable DC switchgear.

Analysis and simulation of the proactive hybrid circuit breaker

2015 IEEE 11th International Conference on Power Electronics and Drive Systems, 2015
High Voltage Direct Current (HVDC) short circuitprotection is a fundamental requirement for any HVDCtransmission system. Presently, all point-to-point links areprotected using circuit breakers on the AC side of theconverters. In order to enable HVDC grids, a more advancedprotection system must be developed. HVDC circuit breakersare one solution for the

Arc-less commutation in hybrid DC circuit breaker

2016 IEEE International Conference on Plasma Science (ICOPS), 2016
DC circuit breaker (DCCB) has been intensively studied due to increasing demand in DC power transmission, such as mega solar power plants and large wind farms. A hybrid DC circuit breaker which consists of electrical contacts, semiconductor devices and a metal-oxide element (varistor) is a promising device to provide a small contact resistance and a ...

Parameter Designing of the DC Hybrid Circuit Breaker

2014 Fifth International Conference on Intelligent Systems Design and Engineering Applications, 2014
This paper introduces the parameter designing of the DC hybrid circuit breaker (CB). In the CB, the current limiting circuit is designed to inhibit the increasing of fault current, the combinatorial electronic power switch is designed to reduce the series connecting number of power electronic device.

Intelligent circuit breaker using thermoelectric hybrid overload protection

2017 20th International Conference on Electrical Machines and Systems (ICEMS), 2017
A three-dimensional finite element model of miniature circuit breaker is established. The steady state temperature field is obtained by the method of electrothermal coupling, and the mechanism of overload protection is analyzed. The influence of wire size on the temperature of bimetal is studied. A simple and effective method to reduce the influence of

An Integrated Multi-port Hybrid DC Circuit Breaker

2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019
A massive number of hybrid DC circuit breakers (HCBs) have to be installed to protect a voltage source converter based multi-terminal DC (MTDC) system, leading to quite high costs. To reduce the implementation cost employing HCB in DC systems, this paper presents an integrated multi-port hybrid DC circuit breaker (IMP-HCB), which consists of an ...
