Woodward 9905‑001

Product Name: SPM‑A Speed and Phase Matching Synchronizer Module, Model 9905‑001SPM‑A
Product Introduction: This is an analog synchronizer module manufactured by Woodward, used for generator set paralleling control. It cooperates with Woodward speed governor to automatically complete generator speed and phase matching, and sends closing signal for generator breaker when matching condition is satisfied, realizing bumpless generator paralleling operation. It applies to diesel engine, gas engine and turbine generator systems.

Description

Technical Specifications:

Nominal input voltage: 115 V AC, 50/60 Hz

Input voltage range: 95‑130 V AC

Maximum power consumption: 5 W

Adjustable phase offset range: 0 to ±10 degrees

Adjustable frequency window: 0.1‑1.0 Hz

Operating temperature range: ‑40 °C to +70 °C

Installation form: Back‑panel chassis mounting

Enclosure type: NEMA 1 equivalent

Functional Features:

Automatically adjusts generator speed bias signal to realize frequency and phase matching with bus voltage.

Outputs contact‑closure signal when synchronization condition reaches preset threshold to close generator breaker.

Provides adjustable phase and frequency window parameters adapting to different generator prime‑mover characteristics.

Does not complete voltage‑matching function; voltage matching shall be finished by other device.

Chassis back‑panel mounting design for cabinet internal installation.

Application Scenarios:

Parallel operation control of multiple diesel generator sets, gas‑engine generator sets and turbine generator units in isolated power grid, marine power station and industrial standby power‑supply systems.

Performance Parameters:

Response time of synchronization logic: 100‑500 ms, adjustable by parameter setting.

Contact output rating: 250 V AC, 2 A resistive load maximum.

Material Composition:

Outer shell: Metal sheet‑metal chassis housing.

Internal main body: Multilayer printed circuit board with analog operational‑amplifier circuit components, relay output unit, potentiometer adjustment components.

Terminal parts: Screw‑type wiring terminals for field‑wiring connection.

Structural Features:

Back‑panel fixed metal chassis structure.

Front‑panel accessible potentiometers for on‑site parameter adjustment.

Screw terminals distributed on chassis edge for signal input‑output connection.

Compact chassis form for standard electrical‑cabinet installation.

Working Principle:

The module collects voltage signals from on‑line bus and standby generator. Internal analog circuit compares frequency difference and phase difference between two signals. It outputs proportional bias signal to prime‑mover speed governor to adjust generator speed. When frequency and phase difference fall within preset window range, internal relay acts to output contact‑closure signal for closing generator breaker to complete paralleling.

Installation Requirements:

Install inside indoor electrical control cabinet on back‑panel mounting surface.

Ensure chassis is reliably grounded.

Adopt shielded twisted‑pair wire for voltage‑signal input wiring.

Keep signal input cable away from high‑power power cable to reduce electromagnetic interference.

Reserve ventilation space around module for heat dissipation.

Complete wiring under power‑off condition.

Usage Notes:

Do not use this module to complete voltage matching task; configure independent voltage‑regulating device.

Set frequency window and phase offset parameters according to prime‑mover dynamic characteristics.

Avoid operating environment with excessive vibration and conductive dust accumulation.

Check terminal screw‑tightening status regularly.

Do not exceed contact output load rating.
