Function
Three parameter synchronization: automatically adjust the voltage, frequency, and phase of the machine to be connected to the grid, aligning perfectly with the bus/grid
Automatic closing: When the synchronization conditions are met, the output relay contact signal drives the circuit breaker to close
Operation mode: Supports four modes: RUN, CHECK, PERMISS, and OFF
Adjustable parameters: phase window, closing delay (dwell time), voltage/frequency tolerance can be set on site
Speed control interface: Output speed bias signal, adjust engine/turbine governor, achieve frequency synchronization
Application
Multiple parallel diesel/gas generator sets and islanded grid connection
Automatic synchronization of ship power station and backup power system
Industrial self owned power plants, secure grid connection of distributed energy sources
