Woodward 9905-765 Load Sharing Signal Module

Product Brief Introduction The Woodward 9905-765 load sharing signal module is a dedicated board for parallel generator sets. It transmits and receives load sharing signals between multiple Woodward controllers, realizes balanced active and reactive load distribution among parallel units, and ensures stable parallel operation of the generator group.
Tag:

Technical Specifications 24VDC power supply, load sharing bus signal processing. Operating temperature: -40℃ ~ +70℃, compatible with Woodward parallel bus.

Functional Features Load signal transmission, load deviation calculation, parallel synchronization auxiliary signal processing, load sharing fault alarm.

Application Scenarios Multiple generator parallel power supply systems, marine multi-unit power grids, standby generator parallel control cabinets.

Performance Parameters Fast load signal response, small load deviation between units, stable parallel operation.

Structural Characteristics Pluggable PCB communication module, load bus status indicator lights.

Working Principle The module exchanges real-time load signals with the load sharing modules of other parallel units through the dedicated bus. The main controller adjusts the speed and excitation according to the load deviation signal to realize balanced load distribution.

Installation Requirements The load sharing bus adopts shielded twisted pair, the bus wiring should follow the daisy chain wiring specification.

Usage Notes All parallel units must use the same type of load sharing module, and the bus terminal resistance needs to be set correctly.
