Transient eddy current distribution in the shield of the passively compensated, compensated pulsed alternator: iron-core machines

Transient Minimization Within Static Var Compensated Distribution Systems

VAR support should be supplied as close to the load as possible to minimize transmission losses. For voltage control and for improvement of total power factor in a distribution system the circuit- breaker switched capacitor banks can be used. The problems with this solution are the voltage steps caused by the large sizes of the capacitor banks as well as the transients caused on insertion. Thyr...

Eddy-Current-Compensated RF Pulse Design for Parallel Excitation

Introduction: High-performance RF coils and shielded Gradient coils [1] for high or ultra high field MRI often require the use of RF shields that are in close proximity to the imaged volume. These shields can sometimes generate Eddy-Currents that are not adequately compensated for using the pre-emphasis algorithm [2] of the scanner. K-space trajectory measurements [3] can be used to compensate ...

Current Directional Protection of Series Compensated Line Using Intelligent Classifier

Current inversion condition leads to incorrect operation of current based directional relay in power system with series compensated device. Application of the intelligent system for fault direction classification has been suggested in this paper. A new current directional protection scheme based on intelligent classifier is proposed for the series compensated line. The proposed classifier uses ...

Fault Location on Compensated Transmission Lines without Current Measurement

This paper presents a novel fault location method for series compensated transmission lines. It is established based on synchronized voltages sampling and Thevenin impedance from both ends of series compensated transmission line. The method is based on the use of phasor measurement units (PMU) technology which is aimed to be independent of current measurements, fault type, fault resistance, fau...
