An algorithm for optimal sizing of the capacitor banks under non-sinusoidal and unbalanced conditions [PDF]

open access: yes, 2014
In non-sinusoidal and unbalanced systems, optimal sizing of the capacitor banks is not a straightforward task as in sinusoidal and balanced systems. In this paper, by means of qualitative and quantitative analysis, it is interpreted that the classical ...

Improved Transformer Differential Protection by Adaptive Pickup Setting during Momentary Over-Fluxing Condition

open access: yesAdvances in Electrical and Electronic Engineering, 2020
The differential relaying scheme is universally adopted as the main protection for power transformer. In certain situations, like temporary over-fluxing, this differential protection may malfunction.

Protection strategy for multi-terminal DC networks with fault current blocking capability of converters [PDF]

open access: yes, 2017
High voltage dc networks are a promising technology to flexibly transmit power over long distances. However, dc grid protection is still a major challenge. DC fault clearance can be mainly achieved with three devices. These are ac circuit breakers (ACCBs)

Dynamic Analyses of the Hydro-Turbine Generator Shafting System Considering the Hydraulic Instability

open access: yesEnergies, 2018
Hydraulic instability is a complex factor causing the vibration of hydro-turbine generator shafting system (HGSS), and the mechanism is the uneven distribution of flow along the circumference.
