9905-760 Woodward Digital Synchronizer and Load Control Module

Description:

Functional Overview
The 9905-760, crafted by Woodward, serves as a Digital Synchronizer and Load Control Module, designed to harmonize multiple generators or energy sources within an electrical network. Its primary function is to align these generators in terms of frequency and phase before interconnecting them to the grid or linking them together. Employing microprocessor technology, this module precisely gauges the frequency and phase angles of the generators, subsequently issuing control directives to fine-tune their outputs. Furthermore, it dynamically modulates the power generation based on real-time load requirements, thereby sustaining consistent voltage and frequency levels throughout the system.

Key Features
Digital Synchronizer Aspects:
- Accurately determines generator frequencies and phase angles.
- Generates commands for output adjustments to synchronize generators.
- Leverages microprocessor capabilities for high-precision synchronization tasks.
- Capable of orchestrating multiple generators operating in tandem.
- Incorporates sophisticated monitoring and protective mechanisms.
- Operates seamlessly in either automatic or manual configurations.

Load Control Module Capabilities:
- Assess load demands and modulate generator outputs accordingly.
- Upholds voltage and frequency stability within the electrical infrastructure.
- Safeguards generators against overload and thermal overrun conditions.
- Facilitates efficient power distribution and collaborative load bearing among units.
- Interacts with external control systems for enhanced coordination.
- Offers dual operation modes: automated and manual intervention.

Cabinet Grounding Specifications
The enclosure housing the module must be a hexahedral metallic structure. It is imperative that cabinet doors are devoid of unshielded windows; instead, they should predominantly consist of solid metal. Should a window be unavoidable, it must attenuate RF signals by more than 20 dB across the range of 10 kHz to 1 GHz.

Cable entry points are exclusively permitted through the enclosure's floor or top surfaces. These apertures should be minimal in size, with the largest dimension not surpassing 152 mm (6 inches), particularly crucial when radio frequency transmitters, like walkie-talkies or mobile phones, are in proximity to these access points.

If RF transmitters can be situated beneath the floor level within the metallic cable pathway, then the dimensions of floor entry points must also adhere to the 152 mm (6 inches) maximum limit. However, if such transmitters cannot be placed below this plane, restrictions on floor entry dimensions do not apply.

Lastly, proper bonding between the cabinet framework and mounting interfaces is mandatory to ensure comprehensive grounding.
