Description
The Woodward 9905-068 2301A is a Load Sharing and Speed Control Module in the 2301A series of controllers. This module is mainly used for generator sets driven by diesel engines, gasoline engines, steam turbines, or gas turbines, and is responsible for controlling the speed of the prime mover and realizing isochronous load distribution when multiple units are connected to the grid.
Applications
Diesel Generator Plants: Enables stable power sharing in multi-generator systems.
Biomass Gas Turbine Plants: Monitors turbine speed across full operating range.
Marine Shipbuilding Plants: Ensures reliable control in harsh marine environments.
Rail Transit Equipment Plants: Supports multiple speed sensors for locomotive systems.
Features and Capabilities
1.Load Sharing and Speed Control
Precise Control: Ensures accurate load sharing among multiple generators
Versatility: Suitable for various types of engines and turbines, including diesel, gasoline, steam, and gas.
2.Installation and Operation:
User Manual: Contains detailed instructions for safe installation and operation.
safety Protocols: Emphasizes adherence to safety guidelines to avoid accidents and equipment damage.
Special Note
Check current transformer phase by measuring the load signal between terminals -11 and +13 with the prime mover stopped, in isochronous mode, and the generator near full load. If correction is needed, test all three CTs and record the required voltage data.
If the engine does not reach the rated no-load speed, check the control and adjust the actuator compensation, gain, and reset potentiometers.
