Woodward 9905-001K SPM-A Synchronizer

Product Introduction

The Woodward 9905-001K SPM-A Synchronizer is a precision automatic synchronizer designed to align generator output with an active power grid or another generator before connection. By controlling voltage, frequency, and phase angle, the SPM-A ensures a seamless transition when paralleling power sources, eliminating the risks of voltage spikes or mechanical stress. Its rugged design and advanced circuitry make it ideal for critical power generation environments such as utilities, marine applications, industrial facilities, and independent power plants. This synchronizer integrates easily with Woodward governors and other control systems, offering dependable, repeatable performance in demanding electrical installations.

Technical Specifications

Applications

• Utility Power Plants: Synchronizes standby or peaking generators with the main utility grid to maintain stable power delivery.

• Marine Power Systems: Integrates shipboard generator sets to ensure safe and smooth connection to onboard busbars.

• Industrial Facilities: Supports backup generators in factories and data centers for uninterrupted power during transitions.

• Independent Power Producers: Enables synchronization of renewable energy sources, such as hydro or biomass generators, to regional grids.

• Emergency Power Systems: Automatically synchronizes multiple gensets for hospitals, airports, or critical infrastructures requiring continuous power.

Advantages

• High Synchronization Accuracy: Maintains precise control of frequency and phase angle for safe, seamless generator-to-grid or generator-to-generator connection.

• Wide Voltage and Frequency Range: Flexible operating parameters ensure compatibility with diverse generator and grid configurations.

• Built-In Protection: Integrated alarms and isolation protect connected equipment from voltage surges or accidental mis-synchronization.

• User-Friendly Integration: Designed for quick installation with Woodward governors and compatible with most modern control systems.

• Industrial-Grade Durability: Wide operating temperature range and robust enclosure guarantee long-lasting performance in harsh conditions.

• Low Power Consumption: Energy-efficient design reduces operational costs while maintaining stable performance.

FAQ

1. What type of output signals does the 9905-001K provide to adjust generator speed and voltage?
   The SPM-A delivers discrete raise/lower pulses to the governor and automatic voltage regulator (AVR), enabling precise frequency and voltage adjustments during synchronization.

2. How does the unit detect when synchronization is complete?
   It continuously monitors voltage, frequency, and phase angle differences. Once all parameters are within the preset limits, it signals the breaker control system to close.

3. Can this synchronizer handle multiple generators operating in parallel?
   Yes. Multiple SPM-A units can be configured to coordinate and synchronize several generators to a single bus or grid.

4. What is the typical response time for frequency and phase corrections?
   The SPM-A responds within milliseconds, providing rapid and stable corrections to ensure smooth paralleling.

5. Does the 9905-001K provide alarms for out-of-limit conditions?
   Yes, it features Form C relay contacts to trigger alarms or inhibit breaker closure if voltage, frequency, or phase conditions deviate from set tolerances.

6. Is it compatible with both 50 Hz and 60 Hz systems?
   Absolutely. The unit automatically accommodates systems operating within the 45–65 Hz frequency range.

7. How does the unit maintain isolation between control circuits and the generator bus?
   It incorporates a 1500 V RMS galvanic isolation barrier to prevent noise or surges from affecting sensitive control electronics.

8. Can the SPM-A be installed in outdoor environments?
   While the electronics are robust, it should be housed in a weatherproof or NEMA-rated enclosure if installed outdoors to protect it from moisture and dust.

9. What type of maintenance is required for reliable operation?
   The unit is solid-state and requires minimal maintenance; periodic terminal inspections and functional testing during routine generator maintenance are recommended.

10. Can this synchronizer integrate with digital control systems or SCADA?
    Yes, the SPM-A provides discrete output signals and alarm contacts that can interface directly with digital supervisory systems for monitoring and control.
