APPLICATIONS

The SPM-D10 is a microprocessor-based synchronizer

designed for use on three phase AC generators equipped

with Woodward or other compatible speed controls and

automatic voltage regulators. The SPM-D10 synchronizer

provides automatic frequency, phase and voltage matching

using either analog- or discrete output bias signals.

The HJV Package provides additional mains protection.

Part-No. 8440-1668 SPM-D1040B/XN is a direct

replacement of the SPM-A synchronizer.

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.
