Brushless Excitation System of Turbo Generator

Komala Koila

The brushless excitation system works in the absence of commutator, slip rings and brushes. Instead of these components we are using Permanent Magnet Exciter and three phase main Exciter with silicon diode rectifier the system has generated. With this system we can avoid dust particles which cause a great maintenance cost. The complete structure of this excitation system is explained clearly in this review. Drawback of this system is presence of considerable exciter time constant which affects the rate of change of voltage.
