Generator Excitation Loss Detection on Various Excitation Systems and Excitation System Failures
2020Generating steadiness of synchronous generator is highly dependent on their exciter as the direct current from excitation system sustains stator and rotor windings magnetically coupled. But generator loss of excitation weakens stator and rotor coupling which result in mechanical and electrical power imbalance and rotor speed rise beyond synchronous ...

Design Aspects of a Novel Brushless Excitation System for Synchronous Machines
International Electric Machines and Drives Conference, 2019In this work design rules for a novel brushless excitation system for externally excited synchronous machines are discussed. The concept replaces slip rings with a fullbridge active rectifier and a controller mounted on the rotor.

Amplidyne main exciter excitation system
Transactions of the American Institute of Electrical Engineers. Part III: Power Apparatus and Systems, 1961The amplidyne exciter combines the basic characteristics of a conventional commutator-type exciter with the buckboost amplidyne features presently used for voltage regulators. The power required to control this exciter is small, permitting new types of voltage regulators to be used and additional, previously impossible exciter functions to be performed.

Double excitations in finite systems
The Journal of Chemical Physics, 2009Time-dependent density-functional theory (TDDFT) is widely used in the study of linear response properties of finite systems. However, there are difficulties in properly describing excited states, which have double- and higher-excitation characters, which are particularly important in molecules with an open-shell ground state.
