Brushless Excitation System Without Using PM Generator: The excitation is being given through the output of the generator itself. Initially when the generator is not started its generation, the power is being given through the external sources such as the d-c generator set or the grid.. Field Excitation and Exciters вЂў DC field excitation is an important part of the overall design of a synchronous generator вЂў The field excitation must ensure not only a stable AC terminal voltage, but must also respond to sudden load changes вЂў Rapid field excitation response is important Three methods of excitation . 1. slip rings link the rotorвЂ™s field winding to an external dc source.
ELECTRICAL ENGINEERING вЂ“ Vol. III - Synchronous Machines - Tze-Fun Chan 4.5. Applications of Synchronous Motors 5. Excitation System Glossary Bibliography Biographical Sketch Summary Synchronous machines are principally used as alternating current (AC) generators. They supply the electric power used by all sectors of modern societies: industrial, commercial, agricultural, and вЂ¦ Static system - excitation is provided by field winding wound on the rotor therefore Slip Rings and Carbon brushes are used. There are no moving components and usually provides a much faster response which improves stability. It is most commonly used in hydro generators.
An algorithm for a monitoring system for automatic excitation regulators in synchronous generators is described. It takes the features of brushless excitation systems into account and provides effective monitoring of their operation. Results from a test of a prototype of the system on a digital. However, for brushless exciters of field wound, synchronous generators, there is significant room for improvement as the impact of the diodesвЂ™ commutations.

This paper presents brushless excitation system which overcomes these faults and has become popular and being employed.. The field excitation is provided by a standard brushless excitation system which consist of rotating armature diode, diode bridge and stationary field. The proposed system captures important characteristics of alternator that include excitation of alternator as well as of brushless AC excitation system is shown in Fig. 3. Fig. 3 Brushless A C Excitation system . 1.5 STATIC EXCITATION SYSTEMS In static excitation system, a portion of the AC from each phase of synchronous generator output is fed back to the field windings, as DC excitations, through a system of transformers, rectifiers, and reactors. An external source of DC is necessary for initial excitation
