6.3.3.1 Bus topology
Bus configurations are processed to divide the main paralleling group into several sub
groups. The algorithm that is used to accomplish this task is called the Grouping Operation
Algorithm (GOA).
The basic bus configurations supported are Single Bus, Ring Bus and Double Bus. In
addition to obtaining VArs or load Current information through communication, this
method has the capability to recognize which transformers are still in parallel in the event
of tiebreakers or switches being opened or closed. Depending on the bus configuration,
each control monitors 1 Line Breaker and 1 or 2 Tie Breakers.
A means to make commissioning of the paralleling system easier, TCC600 provides a
feature to detect all ABB controls that form part of the parallel network. After detection
of the controls, depending on the bus configuration selected, the user can view the
paralleling network as a whole and also individually configure each control.
Single bus
A Single Bus with eight transformers is shown in Figure 348 .
