Revision history [back]

I would recommend that you record a script to do what you want to do in the GUI. Then view that script and read up on what the psspy functions do, in the API manual.

I added a generator (with no P specified), and then changed the power level. As perolofl implied, it is a three step process

Here is such a recording: The first line sets bus 922200 to be a generator bus, or type 2 (Important! Trap for beginners.) The second adds a generator, with ID='2'. The third sets the generator 2 power to 33.33 MW

Here is such a recording: recording. PSSE has done the job in four steps The first line sets bus 922200 to be a generator bus, or type 2 (Important! Trap (Important to do!

The third ID='1', and P=0 MW The fourth sets the generator 2 its power to 33.33 MW
