Woodward 9905-796 Control Unit

Description

The Woodward 9905-796 is a Digital Synchronizer and Load Control (DSLC) unit designed for three-phase AC generators. It is a reduced upgrade model that lacks power factor control and process control functions. This unit is tailored for environments requiring reliable synchronization and load control.

Features

• Digital Technology: Utilizes digital technology for its operation, involving microcontrollers or digital signal processors.
• Synchronization: Ensures that the frequency, phase, and voltage levels of different sources match before they are connected to the power grid.
• Load Control: Manages the distribution of loads among different generators to optimize efficiency and prevent overloading.
• Automation: Comes with automation capabilities, allowing it to perform functions without constant manual intervention.
• Monitoring and Protection: Includes monitoring functions to track the health and performance of generators or loads, and protection mechanisms to prevent damage in case of abnormal conditions.
• Communication: Capable of communicating with other control systems, providing information and receiving commands to ensure coordinated operation.
• Integration: Integrates with other control and monitoring systems within a power plant or grid.
