A Review on Issues and Coordination Strategies for Over Current Protection in Microgrid
2017 14th IEEE India Council International Conference (INDICON), 2017This paper presents a review on issues and coordination strategies for overcurrent protection in microgrid. Microgrid has become more attractive because of its ability to deliver highly efficient, reliable and economic power to the customers. Also, Microgrid has a flexibility to operate in both grid connected and islanded modes of operation.

Fast, configurable over-current protection for high-power modules
2015 IEEE Electric Ship Technologies Symposium (ESTS), 2015Protection from over-current situations and the resulting risk of device failure is a requirement when testing limited-run, experimental modules. This paper demonstrates a fast, configurable, and consistent means for protecting against over-current conditions during Clamped Inductive Load (CIL) testing of 10 kV SiC MOSFET modules.

Design of over-current protection circuit for digital power amplifier
2016 International Conference on Emerging Trends in Electrical Electronics & Sustainable Energy Systems (ICETEESES), 2016This work shows a modified excess current preservation circuitry for digital power amplifier. Excess current is a condition when a greater than required current occurs, which will be dangerous for our instrument. This preservation circuitry is useful to cut off the output buffer when two output pins short-circuit to Vcc, short-circuit to Gnd or short ...

Improving the performance of smart grid over-current protection relays
2011 IEEE PES Innovative Smart Grid Technologies, 2011Due to the significant increase in non linear loads and the worldwide trend to establish smart grids, harmonic level in the electricity grids is significantly increased. In addition to their impact on power quality, harmonic currents can have a devastating effect on power system protection performance especially on the operation of over current relays ...

Study of Over-Current Protection, Electric Arcing, and Fire Prevention
51st AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference<BR> 18th AIAA/ASME/AHS Adaptive Structures Conference<BR> 12th, 2010The contribution of electrical wiring to ballistic threat-induced aircraft fires is a recognized, but poorly quantified vulnerability, particularly as modern aircraft continue to evolve. Electrical systems are increasingly replacing or supplementing mechanical systems.

Analysis and Optimization of LLC Resonant Converter with a Novel Over-Current Protection Circuit
INTELEC 05 - Twenty-Seventh International Telecommunications Conference, 2005A novel over-current protection (OCP) method for a LLC resonant converter has been proposed in this paper. This method is very attractive for its inherent current limit ability, especially under short-circuit condition. Combined with the frequency increasing method, good current limit features can be achieved.

Real-time Implementation of Directional Over-current Protection Coordination in a Microgrid
2018 International Symposium on Recent Advances in Electrical Engineering (RAEE), 2018This research paper is focused at the study and implementation of various protection relays and schemes in LabVIEW software for a small power system. The test power system is indigenously developed in the Lab. Hardware implementation is performed by using common modules available in laboratory, whereas interfacing is done by using LabVIEW.
