Comparative evaluation of four quasi-square wave fed multiphase induction machines
(
IEEE
, 2011 , Conference Paper)
Multiphase winding structures provide induction machines with favorable fault tolerant characteristics. Medium voltage drives have also benefited from the favorable application characteristics of multiphase machines, as ...
Assessment of fault-ride through capability of grid-connected brushless DFIG wind turbines
(
Institution of Engineering and Technology
, 2011 , Conference Paper)
DFIGs are reported to suffer serious reliability problems due to the presence of slip-rings, brushes and gearbox. These disadvantages encouraged several research groups to investigate the viability of employing single-frame ...
Single phase grid connected current source inverter: Mitigation of oscillating power effect on the grid current
(
Institution of Engineering and Technology
, 2011 , Conference Paper)
Although voltage source inverters (VSIs) are the most common DC-AC grid-tied converters, current source inverters (CSIs) are considered to be promising candidate, thanks to their low THD voltages/currents and inherent ...
Static synchronous series compensator for low voltage ride through capability of wind energy systems
(
IET
, 2011 , Conference Paper)
Due to the large increase in number of installed high power renewable energy generating systems such as wind energy power plants, one of the important evolving requirement is riding through the fault at low or zero voltage. ...
Unified power flow controller for low voltage ride through capability of wind-based renewable energy grid-connected systems
(
IEEE
, 2011 , Conference Paper)
Due to the large increase in number of installed high power renewable energy generating systems such as wind energy power plants, one of the important evolving requirement is riding through the fault at low or zero voltage. ...
Harmonic rejection using multi-synchronous reference frame technique for CSI-based distributed generation with grid voltage distortion
(
IEEE
, 2011 , Conference Paper)
In the midst of the growing penetration of renewable energy resources and Distributed Generation (DG), power quality is one of the main concerns. Achieving low total harmonic distortion (THD) of exported current using low ...
A synchronous DQ frame controller via an LCL coupled filter under unbalanced three-phase voltage supply conditions
(
IEEE
, 2011 , Conference Paper)
This paper proposes a synchronous DQ frame current controller for inverter based interfaced systems. The grid voltage may be unbalanced, possibly due to unequal line impedance. The output active and reactive powers oscillate ...
Flywheel energy storage system based on boost DC-AC converter
(
http://dx.doi.org/10.1049/cp.2011.0194
, 2011 , Conference Paper)
An additional DC-DC boost converter is used in conventional configuration of Flywheel Energy Storage System (FESS) to regulate the output voltage during flywheel low speeds. This paper presents a new FESS based on the boost ...
