Woodward 9905-797 Digital Synchronizer Load Control Module

Functional Description

The 9905-797 is a Digital Synchronizer Load Control Module manufactured and designed by Woodward as part of the 9900 Series used in Turbine Control Systems. A Digital Synchronizer Load Control Module is a device or system designed to manage and control the synchronization of multiple digital systems or loads. It ensures that the voltage, frequency, and phase angle of the generator match those of the grid, which prevents damage to the equipment and ensures a stable power supply. A load control module (LCM) regulates the load on a generator to ensure that it operates within its rated capacity. It monitors the load on the generator and adjusts the output of the generator to maintain a constant load. It also protects the generator from overloading and overheating by automatically disconnecting the load in case of a fault.

Features

• Digital Technology: The use of the term Digital implies that the synchronizer module utilizes digital technology for its operation. This could involve microcontrollers, digital signal processors, or other digital components.
• Synchronization: Synchronization is crucial in power systems where multiple generators need to work together to supply electricity. The synchronizer ensures that the frequency, phase, and voltage levels of different sources match before they are connected to the power grid.
• Load Control: Besides synchronization, the module may also have features related to load control. This could involve managing the distribution of loads among different generators to optimize their efficiency and prevent overloading.
• Automation: Digital Synchronizer Load Control Modules often come with automation capabilities, allowing them to perform their functions without constant manual intervention. This is particularly important in large-scale power systems where rapid and precise adjustments are necessary.
• Monitoring and Protection: These modules may include monitoring functions to keep track of the health and performance of the generators or loads. Additionally, they might incorporate protection mechanisms to prevent damage in case of abnormal conditions.
• Communication: In modern power systems, communication capabilities are essential. The synchronizer module may be able to communicate with other control systems, providing information and receiving commands to ensure coordinated operation.
• Integration: Integration with other control and monitoring systems within a power plant or grid is common. This facilitates a holistic approach to managing the entire power generation and distribution system.
