ABB SPTAS01 HR Series turbine control solutions

SPTAS01 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.
