ABB SPTAS01 Symphony Plus Turbine Auto Synchronization Module

ABB SPTAS01 Symphony Plus Turbine Auto Synchronization Module

Functional Description

The Symphony Plus turbine auto synchronization module (SPTAS01) integrates automatic generator circuit

breaker closure into the Symphony Plus control system. The module supports high and low range (eg, 0-150

VAC and 0-50 VAC) generator and line input voltages ambient at either 50 or 60 Hz. The module is capable

of automatically matching line and generator voltage, frequency and phase, and automatic closure of the

generator breaker. The automatic functions can be individually disabled, in which case the module

monitors for the correct conditions but takes no action to modify the parameters.

When the SPTAS01 is in the normal mode and the generator is not synchronized, the module checks the

generator and line voltage inputs continually. The synchronization sequence will not start until the line

voltage is greater than 75% of the target synchronization value, the generator voltage is greater than 33% of

the target synchronization value, and the generator and line frequencies are within the acceptable window

configured by the user.
