The power average operator for unbalanced linguistic term sets
Information Fusion, 2015Abstract In order to aggregate linguistic values of unbalanced linguistic term sets, this paper introduces the linguistic proportional 2-tuple power average operator, which can reflect the relationship among the aggregated values by considering the support for each value from others.

Operating regions of PWM rectifier under unbalanced voltage supply
2009 IEEE International Conference on Industrial Technology, 2009Operation of electric drives may be negatively affected by non-standard conditions in the power network such as voltage unbalance, which may arise in three-phase power networks. The unbalance can be caused by a failure in the network or by unbalanced load in the vicinity of the affected drive.

Unbalanced OWA Operators for Atanassov Intuitionistic Fuzzy Sets
2016In this work we introduce a new class of OWA operators for Atanassov intuitionistic fuzzy sets which distinguishes between the weights for the membership degree and the weights for the nonmembership degree; we call these operators Unbalanced Atanassov Intuitionistic OWA operators.

Performance of synchronous machines operating with unbalanced armature windings
IEEE Transactions on Energy Conversion, 1988The performance of synchronous machines operating with armature windings unbalanced by having coils cut out following winding failure is considered. The resulting unbalanced voltages and currents tend to produce overheating and may produce magnetic pull-over or excessive vibration.

Unbalanced versus balanced operation in an optical coherence tomography system
Applied Optics, 2000The choice of a balanced optical coherence tomography (OCT) configuration versus an unbalanced OCT configuration with optimized reference-arm attenuation is discussed. The choice depends on the receiver noise, the fiber-end reflection R, and the power to the object. When OCT is used to investigate biological tissue an equivalent R?

Unbalanced GSU Transformer Configuration at Rockport Plant - Analysis and Operating Experience
IEEE Transactions on Energy Conversion, 1987This paper describes extensive engineering studies carried out at the American Electric Power (AEP) Service Corporation to determine the feasibility of operating a 1300 MW generating unit with an unbalanced generator step-up (GSU) transformer bank. These studies served as a basis for plans developed to restart AEP's Rockport Plant -- following the ...

Dissipativity-based adaptive and robust control of UPS in unbalanced operation
2001 IEEE 32nd Annual Power Electronics Specialists Conference (IEEE Cat. No.01CH37230), 2002In this paper, we investigate the output voltage control for three phase uninterruptible power supply (UPS) using controllers based on ideas of dissipativity. To provide balanced sinusoidal output voltages even in the presence of nonlinear and unbalanced loads, we first derive a dissipativity-based controller using a conventional /spl alpha//spl beta/ (

Analysis of line-commutated converters during unbalanced operating conditions
IEEE Transactions on Energy Conversion, 1994In this paper, a method of analyzing the salient performance characteristics of line-commutated power converters during unbalanced operating conditions is presented. Simple analytical relationships are established which relate the negative-sequence component of AC current to the negative-sequence component of voltage. These results are verified using a
