ACShort#
Common Parameters: u, name, bus1, bus2
Common Variables: v1, v2, a1, a2
Available models: Jumper
Jumper#
Jumper is a device to short two buses (merging two buses into one).
Jumper can connect two buses satisfying one of the following conditions:
neither bus is voltagecontrolled
either bus is voltagecontrolled
both buses are voltagecontrolled, and the voltages are the same.
If the buses are controlled in different voltages, power flow will not solve (as the power flow through the jumper will be infinite).
In the solutions, the p
and q
are flowing out of bus1
and flowing into bus2.
