The mains synchronization functionality is used to synchronize a genset group to the power grid. Gensets
are put in parallel on the same busbar.
A maximum number of 16 mains synchronizing controllers may coexist on the same Datalink bus.
The mains synchronization may be required for various purposes:
- Soft transfer to/from the grid
- Peak lopping, peak shaving
- Continuous parallel operation with the grid for immediate recovery of power failures
- Power export to the grid
When mains synchronizer functionality is selected, the controller will control the REMOTE START signal
for the genset group.
When sufficient number of gensets are available on the busbar, the controller will synchronize the
complete busbar to the grid, then put them in parallel.
Different operating modes are available in a grid parallel application. The same controller is able to
provide all possible functions.
The controller has various built-
in “mains failure during parallel” protections. These are necessary to
prevent the genset system feeding the grid. Protections are capable of isolating gensets from the grid as
fast as 2 to 5 cycles.
