5.10 DEAD BUS SYNCHRONISING (AUTO MODE)
NOTE: For further details on Dead Bus Synchronising, refer to DSE Publication: 056-072
Dead Bus Synchronising Training Document.
5.10.1 BENEFIT OF SYSTEM
Generator set specifications often contain the requirement for the set to be on load within 15 seconds
of a mains supply failure. This is easily achievable in single set applications. However in the current
era of fuel conservation, multiple sets are often used to provide the backup power solution for many
applications. This gives challenges in starting and synchronising the required sets before they can be
used to power the load.
The solution to this is a longstanding one, having being used for many decades. However modern
digital communications such as the DSE MSC link has vastly improved the control and hence safety
of the system operation. The solution is called Dead Bus Synchronising. Using Dead Bus
Synchronising, any number of generators are able to be online and in parallel potentially within 15
seconds, depending upon applications and hardware used.
5.10.2 HARDWARE REQUIREMENTS
DSE8660 MKII controller
DSE8610 MKII controller
DC controlled generator load switch
Auxiliary contact to feed back generator breaker status to the DSE controller.
External relay driven by the DSE module to isolate the supply to the AVR inside the
generator’s alternator.
Speed detection using an MPU or CAN signal.
