SPM-D11 (ASG 411)

Synchronizer and Load Share Unit

The SPM-D11 is a microprocessor-based synchronizer designed for use on one or three-phase AC generators equipped with Woodward or other compatible speed controls and automatic voltage regulators. The SPM-D11 synchronizer provides automatic frequency, phase and voltage matching using either analog- or discrete output bias signals.
It combines synchronizing for one circuit breaker, load and power factor control or isochronous load sharing and generator protection.

Common Features:

• Phase match or slip frequency synchronization with voltage matching
• 2-phase sensing of generator and busbar
• Synchronization time monitoring
• Load/var sharing
• Real power control
• True RMS power calculation
• Generator real power set point by parameter or via 0/4 to 20 mA
• Soft unloading
• Power factor control
• Power factor set point by parameter
• Power limit value with relay output
• Discrete raise/lower for speed/load
• Discrete raise/lower for voltage/power factor
• Two-line Liquid Crystal display
• Operation and alarm indication
• Control activity and breaker state indication
• Synchroscope
• Generator/busbar value display
• English/German display language
• PC and front panel configurable

Protection Functions:

• Generator over/undervoltage (ANSI# 59/27)
• Generator over/underfrequency (ANSI# 81O/U)
• Generator overload (ANSI# 32)
• Generator reverse/reduced power (ANSI# 32R/F)
