An effective fault management scheme and comprehensive double line‐frequency ripple propagation analysis for MVDC networks

IET Generation, Transmission & Distribution, 2021
This paper proposes an effective fault management scheme for medium‐voltage direct current (MVDC) networks, which includes a virtual‐impedance‐based fault current limiter (VI‐FCL) on the DC side and a positive‐negative‐sequence (PNS) control scheme on ...

A voltage-clamped bidirectional fault current limiter based on a three-winding coupled inductor for DC power grids

International Journal of Electrical Power & Energy Systems
The DC fault is a serious challenge to voltage-source-converter-based HVDC (VSC-HVDC) systems, and the fault current limiter (FCL) is one of the key measures to solve the DC fault and reduce the capacity of the DC circuit breaker.

Improved Low Voltage Ride-Through Capability of DFIG with ESO Controller under Unbalanced Network Conditions

Majlesi Journal of Electrical Engineering
Under unbalanced grid condition, in a Doubly-Fed Induction Generator (DFIG), voltage, current, and flux of the stator become asymmetric. Therefore, active-reactive power and torque will be oscillating.
