Woodward SPM-D 8440-1706/D Generator Synchronous Parallel Controller
8440-1706/D is a Woodward SPM-D11 series microprocessor based generator synchronous parallel controller , manufactured in Poland, and is a discontinued spare part mainly used for grid control of AC generator sets.
8440-1706/D Core function: Complete automatic matching of voltage, frequency, and phase between the generator and the power grid, and achieve synchronous closing of circuit breakers; 8440-1706/D supports active and reactive load distribution among multiple units, and integrates generator protection function to prevent damage to units caused by reverse power, overvoltage, undervoltage and other faults. It can complete control logic such as isolated grid operation, busbar no voltage closing, soft unloading, power factor adjustment, etc. It is often used in conjunction with speed regulators and AVR voltage regulators to ensure the safe and stable operation of parallel power supply systems for generator units.

Product features
- Based on microprocessor digital operation, it supports two grid connection modes: phase synchronization and sliding frequency synchronization. The synchronization time can be monitored and it has synchronization verification function.
- Integrate true effective value power calculation, support multi unit active and reactive load sharing, support soft unloading, and power factor setting adjustment.
- Built in comprehensive generator protection logic: reverse power, overvoltage, undervoltage, overcurrent and other fault detection, fault relay alarm output.
- Supports multiple operating modes: parallel connection of mains power, isolated network operation, and no voltage busbar closing.
- Channel isolation design, strong industrial anti-interference ability; Equipped with a built-in LCD display panel, it allows for on-site viewing of parameters, fault alarms, and completion of parameter settings.
- Analog+relay output, can be connected to Woodward or other brands of speed controllers and voltage regulators.
