IoT based over Current Protection Control System using for Micro Grids

2021 6th International Conference on Inventive Computation Technologies (ICICT), 2021
Microgrids are local electric and load networks which can be used by chip-level materials to form part of a broader power infrastructure or an individual power grid. Micro-grid will help the business transition from non-renewable to reliable and renewable energy. Their implementation in current chip-level systems will be updated.

A new IGBT with a monolithic over-current protection circuit

Proceedings of the 6th International Symposium on Power Semiconductor Devices and Ics, 2002
A new IGBT structure with a monolithic overcurrent sensing and protection circuit has been developed. The feature of this device is a novel integration of a sensing and protection circuit which consists of a sensing IGBT, lateral n-MOSFET, polycrystalline silicon diode and resistor with an IGBT structure.

Adaptive over current protection for distribution feeders with distributed generators

IEEE PES Power Systems Conference and Exposition, 2004., 2005
The connection of distributed generators (DG) to distribution networks influences the performance of the networks. This paper focuses on the impact of DG on the feeder protection, specifically the impact on the overcurrent (OC) relay performance. The paper presents simulation results to show the extent of deterioration a DG can cause on the OC relay ...

Improving the performance of smart grid over-current protection relays

2011 IEEE PES Innovative Smart Grid Technologies, 2011
Due 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 ...

Protection of microgrid through coordinated directional over-current relays

2014 IEEE Global Humanitarian Technology Conference - South Asia Satellite (GHTC-SAS), 2014
Microgrids integrate distributed energy resources to provide reliable, environment friendly and economic power to small/medium sized urban communities or to large rural areas. Due to the existence of generators at all levels of the distribution system and two distinct operating modes, i.e.

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, 2010
The 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.

Design of over-current protection circuit for digital power amplifier

2016 International Conference on Emerging Trends in Electrical Electronics & Sustainable Energy Systems (ICETEESES), 2016
This 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 ...

Solid-state Over-current Protection for Industrial DC Distribution Systems

4th International Energy Conversion Engineering Conference and Exhibit (IECEC), 2006
We describe a concept for circuit protection and fault current limitation in DC power systems based on the use of solid-state power switches. The approach could be useful in the increasingly widespread application of DC power distribution networks. During normal operation the power switch is always "on".

A High Reliable Over-Current Protection Circuit with Low Power Consumption

2013 5th International Conference on Intelligent Human-Machine Systems and Cybernetics, 2013
This paper shows a kind of over-current protection circuits used to power management with the function of pre-comparison, low power consumption and rapid response ability. Power consumption is mainly by the pre-comparison circuits detecting current in real time with low power consumption. The later stage circuits begin to work once load current exceeds
