FAQ

What is the main function of the Woodward 9905-946 Automatic Synchronizer?
The 9905-946 automatically matches the generator’s frequency, voltage, and phase angle with the bus or another generator, ensuring safe and smooth synchronization before circuit breaker closure.

How does the 9905-946 achieve synchronization accuracy?
It uses digital phase-locking algorithms to continuously compare the generator and bus parameters, adjusting speed and excitation until the phase difference is within ±1°.

What type of systems can this synchronizer be used with?
The module is suitable for use with diesel and gas engine-driven generators, turbine systems, and marine power management systems requiring automatic synchronization.

Can the 9905-946 be integrated with external control systems?
Yes, it includes an RS-232 communication interface allowing integration with Woodward governors, voltage regulators, and supervisory control systems.

What happens if the synchronizer detects unsafe synchronization conditions?
If voltage, frequency, or phase deviation exceeds preset limits, the unit blocks breaker closure and indicates a synchronization fault to prevent equipment damage.

How does the device handle dual or parallel generator operation?
It can manage parallel operation by automatically synchronizing multiple generators sequentially to a common bus, ensuring balanced load sharing after synchronization.

Is there a manual synchronization option available?
Yes, the 9905-946 supports manual control through front panel switches or remote operator panels for field calibration or emergency operation.

What are common applications of the Woodward 9905-946 Automatic Synchronizer?
It is commonly used in power plants, industrial generator systems, marine vessels, and backup power installations where precise and safe generator synchronization is essential.
