Design and Construction of Inverse Time & Definite Time Overcurrent Relay Based on Arduino Uno

Emitor: Jurnal Teknik Elektro
This system is designed to detect overcurrent faults, then disconnect them from the circuit. In inverse time overcurrent relay, the relay trip time will depend on the magnitude of the fault current.

Active Power Control of Full‐Scale Converter‐Based Wind Turbine Considering Turbine Angular Velocity for Short‐Term Frequency Stability in Power Systems

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
The increasing deployment of wind turbine generators (WTs) may alter the frequency stability of power systems. Unlike traditional synchronous generators, WTs are connected to the power system through converters. Consequently, WTs cannot provide an inertia response to the power system. Nevertheless, the converters can perform rapid control.

A Review of Transient Support and Security‐Stability Enhancement Control Strategies for Grid‐Forming Voltage Source Converter‐Based High Voltage Direct Current Transmission

High Voltage, EarlyView.
ABSTRACT Amid the ongoing global energy transition, the short‐circuit ratios of AC power grids are continuously decreasing. Grid‐forming voltage source converter‐based high voltage direct current transmission (GFM VSC‐HVDC) systems have therefore come to the forefront of attention.
