Boost inverter-based HVDC transmission system with inherent blocking capability of AC side contribution during DC side faults
(
Elsevier Ltd
, 2014 , Article)
Semiconductor advancements in the past three decades have positioned the voltage source converter-based HVDC (VSC-HVDC) solution as a practical and popular alternative to its line-commutated converter high voltage DC ...
An Improved Fault Tolerant Five-Phase Induction Machine Using A Combined Star/Pentagon Single Layer Stator Winding Connection
(
IEEE
, 2015 , Article)
One of the main merits offered by multiphase machines is their high fault-tolerant capability. Literature has demonstrated that the performance of multiphase induction machines under fault conditions is affected by the ...
A Droop Control Design for Multiterminal HVDC of Offshore Wind Farms With Three-Wire Bipolar Transmission Lines
(
IEEE
, 2015 , Article)
Converting existing ac transmission lines to an extended multiterminal three-wire bipolar HVDC system can be considered a cost-effective way to interconnect dispersed offshore wind farms to onshore ac grids instead of ...
A static three-phase to five-phase transformer based on Scott connection
(
Elsevier B.V.
, 2014 , Article)
Multiphase machines have become challenging candidates for safety-critical applications that require wide fault tolerant capabilities and higher system reliability. However, this adds more complexity to the adopted power ...
Parameter identification of five-phase induction machines with single layer windings
(
IEEE
, 2014 , Article)
Despite the increased interest in multiphase induction machines for safety-critical applications, machine parameter identification for the different sequence planes is still a challenging research point. In most available ...
An interline dynamic voltage restoring and displacement factor controlling device (IVDFC)
(
IEEE
, 2014 , Article)
An interline dynamic voltage restorer (IDVR) is invariably employed in distribution systems to mitigate voltage sag/swell problems. An IDVR merely consists of several dynamic voltage restorers (DVRs) sharing a common dc ...
A series flywheel architecture for power levelling and mitigation of DC voltage transients in multi-terminal HVDC grids
(
Institution of Engineering and Technology
, 2014 , Article)
This study proposes a new architecture of flywheel energy storage system (FESS) which can be implemented at generating unit (GU) level (e.g. wind turbine) or scaled up for application in grid-side converter (GSC) stations ...
Four-switch three-phase SEPIC-based inverter
(
IEEE
, 2014 , Article)
Four-switch three-phase (FSTP) inverter has been proposed as an innovative inverter design to reduce the cost, complexity, size, and switching losses of the DC-AC conversion system. Traditional FSTP inverter usually operates ...
Single-Stage Three-Phase Differential-Mode Buck-Boost Inverters with Continuous Input Current for PV Applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Differential-mode buck-boost inverters have merits such as reduced switch number, ability to provide voltages higher or lower than the input voltage magnitude, improved efficiency, reduced cost and size, and increased power ...
Design of Optimal Droop Control for Multi-Terminal High-Voltage Direct Current Systems During Line Outages
(
Taylor and Francis Inc.
, 2019 , Article)
This article investigates the required modifications to droop control design for optimum operation of Multi-Terminal High-Voltage Direct Current (MTHVDC) systems during line and converter outages. A typical 6-bus MTHVDC ...
