Static Parallel Connection - Smartgen HGM9510N User Manual

18 STATIC PARALLEL CONNECTION

Static parallel connection function can be chosen by a digital input port.
It applies to fast parallel connection occasions. All gensets disconnect generator excitation and close
the switch to start at the same time. After all the generators' speed is up to the loading speed and
meanwhile excitation signals are issued. At this time the generator voltage is formed and the genset
parallel connection is completed. This procedure spares the time used in the normal parallel connection
process when the genset is waiting for all synchronous conditions are satisfied and then close the
switch to start. If the genset cannot realize the excitation output condition during the "Static Parallel
Delay" period, it exits from "Static Parallel" mode and changes to normal parallel connection mode. The
genset opens the switch and excitation outputs. It will wait and until all synchronous conditions are
satisfied it closes and starts to work.
This function applies to soft-start loading occasion. For example: when the genset connects to the
transformer.
