Woodward 9905-795 Digital Synchronizer And Load Controller

FAQ

Q1: What is the main purpose of the Woodward 9905-795 Digital Synchronizer and Load Controller?
A1: It is designed to automatically synchronize multiple generators to a common bus and manage load sharing to ensure stable and efficient power generation.

Q2: How does the synchronizer detect synchronization conditions?
A2: The unit continuously monitors voltage, frequency, and phase angle between the generator and the bus to initiate synchronization when parameters match within specified limits.

Q3: What types of generators can this controller be used with?
A3: It supports both diesel and gas engine-driven generators and can be integrated with Woodward or third-party speed and voltage control systems.

Q4: How is load sharing managed between multiple generators?
A4: The controller uses analog and digital communication to distribute load proportionally across all connected generators, maintaining system balance and preventing overloads.

Q5: What communication protocols does the 9905-795 support?
A5: It supports RS-232 for configuration and monitoring, with optional CANopen for networked generator control applications.

Q6: Can the unit provide protection during synchronization errors?
A6: Yes, it automatically prevents breaker closure if frequency, voltage, or phase angle are outside safe limits, protecting the generator and grid equipment.

Q7: Is it possible to adjust synchronization and load-sharing parameters?
A7: Yes, all control parameters including frequency, voltage thresholds, and load bias can be configured through software or front-panel interface.

Q8: In what applications is the 9905-795 typically used?
A8: It is commonly used in power plants, marine systems, and industrial facilities requiring precise generator synchronization, load management, and automatic paralleling control.
