Tradeoffs between AC power quality and DC bus ripple for 3-phase 3-wire inverter-connected devices within microgrids [PDF]
, 2011 Visions of future power systems contain high penetrations of inverters which are used to convert power from dc (direct current) to ac (alternating current) or vice versa.

The performance of a 3-Phase Induction Machine under Unbalance Voltage Regime [PDF]
, 2017 In industries, electric motors contribute a major percentage of electrical loads, and by implication, a major portion of the generated electrical energy is consumed by electric motors, and it is therefore vital to ensure that these motors operate with ...

Secondary voltage unbalance compensation for three-phase four-wire islanded microgrids [PDF]
2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14), 2014 This paper proposes a secondary voltage unbalance control approach that compensate voltage unbalances in three-phase four-wire islanded microgrid systems. It is implemented in the secondary control level of the microgrid hierarchical control structure.

P-class phasor measurement unit algorithms using adaptive filtering to enhance accuracy at off-nominal frequencies [PDF]
, 2011 While the present standard C.37.118-2005 for Phasor Measurement Units (PMUs) requires testing only at steady-state conditions, proposed new versions of the standard require much more stringent testing, involving frequency ramps and off-nominal frequency ...

Modeling and analysis of nonlinear rotordynamics due to higher order deformations in bending [PDF]
, 2011 A mathematical model incorporating the higher order deformations in bending is devel- oped and analyzed to investigate the nonlinear dynamics of rotors. The rotor system con- sidered for the present work consists of a flexible shaft and a rigid disk. The
