6.4 SINGLE GENSET PARALLEL WITH MAINS

A single controller is able to provide all the functionality required in order to control a genset running in
parallel with the grid.
Parallel operation with the grid 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
GENSET
When AMF functionality is selected, there are a number of adjustable parameters causing parallel
operation to the grid:
-Peak lopping enable: the load is supplied by mains and genset at the same time.
-Soft transfer enable: load transfer between mains and genset is performed in parallel mode.
-Power export enable: the genset supplies power to the grid.
Continuous parallel operation for immediate recovery of mains failures is achieved in peak lopping mode.
Power may be exported to the grid, or load may be shared between grid and genset, or simply soft
transfers may be performed. 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 protections for "mains failure during parallel operation". These are
necessary to prevent the genset system from feeding the grid. Protections are capable of isolating the
genset from the grid as fast as 2 to 5 cycles.
