Inrush Current Mitigation for Grid-Forming Inverters in Islanded Microgrids
European Conference on Cognitive Ergonomics, 2022Virtual-inertia and droop control methods are commonly used for grid-forming inverters. While the virtual inertia is used to emulate the equation of motion/frequency, if the inverter output voltage is emulated as in synchronous generators, then the ...

A Simplified Phase-Controlled Switching Strategy for Inrush Current Reduction
IEEE Transactions on Power Delivery, 2021High inrush current severely threats the safe operation of the power system and transformers, which may lead to mal-operation of overcurrent protection device, internal short-circuit fault in transformers.

Inrush Current of Superconducting Transformer
IEEE Transactions on Applied Superconductivity, 2013Inrush current in superconducting transformers is a little-known phenomenon. Because of its high values and long time, it may lead to loss of superconductivity in transformer's windings. In the article, we present results of inrush current measurements in two superconducting transformers of the same power but different winding geometries.

IEEE transactions on industry applications, 2021
In this article, a new saturated amorphous alloy core-based inrush current limiter (ICL) has been designed and built to limit the inrush current of a power transformer. A toroidal core with a middle limb is developed using the Metglas amorphous alloy and

Prediction and Control of Transformer Inrush Currents
IEEE Transactions on Magnetics, 2015In this paper, we propose a dynamic model of the electrical transformer suitable for the numerical prediction of the inrush currents due to the arbitrary initial excitation of a transformer after a switch-OFF. In particular, the proposed model can be helpful to control strategies to avoid a transient current overshoot, based on the prediction of the ...

Calculation of the Magnetic Field and Inrush Current in a Three-phase Transformer
2020 Applying New Technology in Green Buildings (ATiGB), 2021When a power transformer is connected to the grid, the inrush current increases substantially with a high value of harmonic components. At that time, the amount of flux in the core increases causing the magnetic circuit to saturate with a duration up to ...

Practical Scenarios to Evaluating Inrush Current Detection Function
2025 International Conference on Protection and Automation of Power Systems (IPAPS)Distinguishing between fault and inrush current (IC) is a significant challenge for protective relays. Actually, the presence of a second harmonic in the IC waveform is one of their biggest distinctions.
