A clamping type DC circuit breaker with short fault isolation time and low energy dissipation

نویسندگان

چکیده

The development of DC grids faces challenges from fault protection. conventional circuit breaker (DCCB) employs metal-oxide varistor (MOV) to isolate the faulted line, in which isolation process is coupled with energy dissipation process. In this study, a clamping type DCCB (CTCB) uses internal capacitors clamp converter voltage proposed. Thanks proposed configuration, and are decoupled, resulting fast low compared DCCB. working principle CTCB presented verified grid simulation model. A comparison made traditional time can be reduced by 34.5 %. dissipated 17.4 power 76.2 1

A New Circuit Topology for Open Circuit and Short Circuit Fault Tolerant Dc - Dc Converter

This paper describes a new design for a fault tolerant Hbridge dc-dc converter. Open circuit and short circuit fault tolerance is achieved using multilevel converter topology in combination with pulse width modulation control strategy allowing a large set of converter switching states to produce bidirectional power flows at any required output voltage. If two switches fail at particular instant...

Investigating Impacts of Sustainable Repair Time and Circuit Breaker Model on Meshed Distribution Networks Reliability Assessment

Generally, the failure rate and the repair time of system components are constant parameters in reliability assessment of electric distribution systems. A failure of component is resulted from failing in the operation or overloading. In addition, there exist cases where, the repair times of components are small and tolerable from customer point of view. Thus, tolerable repair times may be overl...

Energy dissipation in an adaptive molecular circuit

The ability to monitor nutrient and other environmental conditions with high sensitivity is crucial for cell growth and survival. Sensory adaptation allows a cell to recover its sensitivity after a transient response to a shift in the strength of extracellular stimulus. The working principles of adaptation have been established previously based on rate equations which do not consider fluctuatio...
