Towards the development of a two-time scale CUEP/BCU method
(IEEEManhattan, 2013-09)
This paper proposes a new Two-Time Scale (TTS)
BCU method, and reports the first ever known use of the TTSCUEP
method in a multi-machine power system. The proposed
TTS-BCU method is a numerical algorithm to correctly ...
Numerical correction for the diffuse solar irradiance by the melo-escobedo shadowring measuring method
(2011-12-01)
The present paper deals with numerical corrections factors proposed as a function of the clearness index in order to correct the diffuse solar irradiance measured with the Melo-Escobedo Shadowring Measuring Method (ME ...
Distortional buckling of simple lipped channel in bending results of the experimental analysis versus direct strength methods
(2006-12-01)
Cold-formed steel members are subject to failure caused by buckling, normally under loads smaller than those corresponding to partial or total yielding of the cross section. The buckling of members in bending can be ...
Constraints implementation for IQML and mode direction-of-arrival estimators
(2000-12-01)
The iterative quadratic maximum likelihood IQML and the method of direction estimation MODE are well known high resolution direction-of-arrival DOA estimation methods. Their solutions lead to an optimization problem with ...
Transient stability indices from a hybrid approach
(2001-12-01)
This paper deals with hybrid method for transient stability analysis combining time domain simulation and a direct method. Nowadays, the step-by-step simulation is the best available tool for allowing the uses of detailed ...
Comparison between Lebaron-Perez and Dal Pai-Escobedo correction methods for diffuse irradiance measured by the meo shadowring method
(2017-01-01)
This study aims to determine the effectiveness of two methods of correction of diffuse irradiance measured with shadowbands: LeBaron-Perez method and Dal Pai-Escobedo method. For the LeBaron-Perez method, we use the original ...
Crack Detection and Dynamic Analysis of a Cracked Rotor with Soft Bearings Using Different Methods of Solution
(2019-01-01)
The ratio of bearing stiffness to the shaft stiffness has a significant impact on the lower frequencies, mode shapes and, consequently, the whirl orbits. Most works studying crack detection methods in rotating systems use ...
Influência do TCSC na energia transitória dos sistemas de potência
(2005-12-01)
The problem of power system stability including the effects of Flexible Alternating Current Transmission System (FACTS) is approached. The Controlled Series Compensator is considered, and its effects upon synchronizing and ...
Effects of FACTS devices on power system performance in view of small-signal or great disturbances
(2003-01-01)
The problem of power system stability including the effects of Flexible Alternating Current Transmission System (FACTS) is approached. The Controlled Series Compensator and the Static Var Compensator (SVC) are considered, ...
Dynamic analysis of a new piezoelectric flextensional actuator using the J1-J4 optical interferometric method
(2005-12-01)
Piezoelectric actuators are widely used in positioning systems which demand high resolution such as scanning microscopy, fast mirror scanners, vibration cancellation, cell manipulation, etc. In this work a piezoelectric ...
