Woodward 9907-029

الوصف

The Woodward 9907-029 is an SPM-A Synchronizer (Speed and Phase Matching Synchronizer). This is a specialized control module designed to automatically match the speed, phase, and voltage of a generator to a bus or another generator before closing the circuit breaker.

Key Features and Applications

The SPM-A Synchronizer is a key component in power generation systems that involve paralleling generators. It ensures a smooth and safe transition when connecting two power sources, preventing damage that could be caused by an abrupt connection.

• Automatic Synchronization: The primary function is to automatically synchronize a generator to a live bus. It adjusts the generator’s speed, phase angle, and voltage to match the bus frequency, phase, and voltage.
• Voltage Matching: Unlike some other models in the series (e.g., the 9907-028), the 9907-029 includes voltage matching capabilities. It can match voltage with a precision of 1%, which is crucial for stable and efficient operation when paralleling.
• Compatibility: This module is compatible with other Woodward units, such as the 2301, 2301A, EPG, and 2500 series controls. It works by sending raise/lower speed signals to the generator’s governor and voltage-adjusting signals to the AVR.
• Operating Modes: The unit has several selectable operating modes, including OFF, RUN, CHECK, and PERMISSIVE. This allows for flexible control depending on the specific application needs.
• Adjustable Dynamics: The controller has fully adjustable parameters and dynamics that can be tuned to match the characteristics of the attached engine, whether it’s a small engine or a large turbomachinery like a diesel, gas, or steam turbine.
