Woodward easYgen | exciter-10 Excitation module for synchronous generators

DESCRIPTION

Woodward’s easYgen | exciter-10 (EX-10) module is a power electronics

component designed to provide excitation current to the generator that is

controlled by the Active Voltage Regulator (AVR) feature in the easYgen

3400/3500XT genset controls.

The active voltage regulation concept intends to substitute a traditional

voltage regulation configuration by simplifying the overall topology. The

easYgen internal controller regulates generator output voltage by sending a

pulse width modulation (PWM) signal to the excitation module. The excitation

module controls generator excitation and therefore generator output voltage.

This topology eliminates the redundant voltage and current sensing from a

traditional voltage regulator and also makes a feedforward control architecture

at AVR level simplifying the cascaded PID control topology. For power input,

EX-10 interfaces with any of the following excitation systems: Self/Shunt

Excitation, Auxiliary winding/AREP Excitation and Permanent Magnet (PMG)

Excitation systems to make it a standard yet versatile solution.
