Woodward 8440-2165 SPM-D2-11/LSXR Load Distribution Controller
Woodward 8440-2165 SPM-D2-11/LSXR is a microprocessor based generator synchronization and load distribution controller launched by Woodward in the United States, belonging to the SPM-D series. 8440-2165 is used for automatic synchronization and load sharing of three-phase AC generators, and is widely used in key power generation scenarios such as power plants, cogeneration, and emergency power stations.
Main functions and features
- Fully automatic synchronous grid connection: automatically matching the frequency, phase, and voltage of the generator and busbar to achieve impulse free closing.
- Load sharing (LSXR): Automatically distributes active/reactive loads when multiple machines are connected in parallel to avoid unbalanced loads.
- High precision PID control: outputting speed/excitation bias signals, with fast response and high stability.
- Wide bandwidth and voltage adaptation: 47-63 Hz, 100 VAC input, compatible with global power grids.
- High reliability: Industrial grade design, wide temperature operation, suitable for harsh environments such as power plants/offshore platforms.
- Display and operation: with a high brightness display screen, real-time monitoring of synchronization status; Key configuration parameters.
