overview：
Woodward 8440-1706 SPM-D11/LSXR is a digital synchronizer used to synchronize generators with the grid or multiple generator sets. It can control the frequency and phase of the generator to ensure its safe connection to the grid or parallel operation with other units.
It has an automatic synchronization function and can monitor the frequency, phase and voltage difference between the generator and the grid or other units. After the generator is connected to the grid, the synchronizer can distribute the load, maintain the stability of the system frequency, balance the load between multiple generators, and avoid equipment overload or uneven load.
Fuctions & Features:
- Automatic synchronization function: Woodward 8440-1706 has a fully automatic synchronization capability, which can monitor the frequency, phase and voltage differences between the generator and the grid or other generator sets.
- Load distribution and frequency control: After the generator is connected to the grid, Woodward 8440-1706 can distribute its load to maintain the stability of the system frequency. It can balance the load between multiple generators to prevent overload or unbalanced load on individual devices.
- Multi-function display and monitoring: Woodward 8440-1706 is equipped with a multi-function display, through which users can monitor the key parameters of the generator in real time, such as frequency, phase, load, etc.
