PSSE bus codes

asked Oct 17 '12

A reference of all the bus types in PSSE.

Type 1: Load Bus
Type 2: Generator Bus
Type 3: Swing Bus
Type 4: Disconnected
Type 5: Load Bus (at boundary of an area)

Have you ever used Type 5? I only came across it today in my research.

Here is how to create a new type 1 bus

busnumber, busname = 20020, "PARK_2"
psspy.bus_data_2(i=busnumber, intgar1=1, name=busname)

Beware though, if bus number 20020 already existed then this would change it's type and name - It wouldn't create a new bus at all.

I had this (type 5) error crop up using

psspy.extr(0)

to extract sbs 0, where there were branches to deleted buses connected to in service buses they became type 5. An interim fix (as you can't actually do any operations with a type 5 bus in the case) is to use

psspy.extr(0,0,[0,0])
