Woodward 8440-1666/E Synchronizer and Load Distribution Controller
Woodward 8440-1666/E belongs to the SPM-D11 series generator automatic synchronization and load distribution controller. A cabinet mounted panel controller is used for diesel and gas generator sets to achieve automatic synchronous closing, phase/frequency/voltage matching, and load sharing management between multiple generators and between generators and the power grid.
Main function
- Automatically detect the voltage, frequency, and phase difference between the standby machine and the bus, complete automatic synchronization, control the circuit breaker to close, and achieve safe grid connection/parallel operation of the generator set.
- Implement active and reactive load distribution among multiple units to avoid single machine overload or load drift.
- Provide protection interlocks such as synchronization failure, voltage abnormality, and frequency abnormality to prevent damage to the generator caused by asynchronous closing.
- Local display of electrical parameters of the unit, and external output of communication and switch signals, connected to DCS and PLC upper monitoring systems, supporting remote monitoring of the unit’s parallel status.

Product features
- Fully automatic synchronous closing: automatically tracks voltage, frequency, and phase, and outputs closing instructions when synchronization conditions are met; Simultaneously retaining manual synchronization mode for easy debugging and maintenance.
- Active and reactive load sharing: When multiple units are running in parallel, active and reactive loads are automatically allocated to suppress load offset and ensure the stability of the parallel system.
- Improve synchronous protection logic: equipped with non synchronous locking, voltage over limit, frequency over limit protection, prohibit closing when conditions are not met, and protect the generator and switchgear equipment.
- Panel LCD+LED status indicator: Two rows of LCD display real-time voltage, frequency, and phase difference on both sides; The LED indicator light provides intuitive feedback on the closing, fault, and synchronization status, allowing for local troubleshooting.
- Standard communication interface: RS485 Modbus RTU, which can be connected to DCS and PLC to achieve remote parameter reading, alarm, and status monitoring.
- Panel opening installation: Cabinet panel embedded installation, front panel IP42 protection, rear terminal IP24, suitable for industrial environments with high dust and strong electromagnetic interference in power plant control cabinets.
- Parameter software configuration: The synchronization threshold, load distribution coefficient, and protection threshold can be modified through the upper configuration software to adapt to different power generator sets.
- Wide voltage DC power supply: 18-36VDC power supply, suitable for industrial battery power supply system, wide temperature operation from -40 ℃ to+70 ℃, strong anti vibration and anti electromagnetic interference ability.
Usage Scenarios
- Factory owned power station: Multiple diesel/gas generator sets are connected in parallel, with mutual switching, grid connection, and load sharing control between the units.
- Oil and gas, petrochemical site backup power supply: The backup generator set of the petrochemical plant is synchronized with the plant power grid to ensure uninterrupted process power supply.
- Auxiliary power generation system for power plants and thermal power plants: synchronous parallel control of small steam turbine generators and biogas generators.
- Backup power supply for data centers and large commercial complexes: Multiple high-power backup generators automatically switch in parallel to ensure emergency power supply.
- Ship and offshore platform generator sets: Multiple auxiliary generators on board are connected in parallel for synchronization and load distribution control.
- Off grid isolated power supply system for industrial and mining enterprises: Multiple units operate in parallel on isolated islands without an external network to achieve load balancing.
