PSS#
Power system stabilizer group.
Common Parameters: u, name
Common Variables: vsout
Available models: IEEEST, ST2CUT
IEEEST#
IEEEST stabilizer model. Automatically adds frequency measurement devices if not provided.
Input signals (MODE):
Rotor speed deviation (p.u.),
Bus frequency deviation (p.u.) (*),
Generator P electrical in Gen MVABase (p.u.),
Generator accelerating power (p.u.),
Bus voltage (p.u.),
Derivative of p.u. bus voltage.
(*) Due to the frequency measurement implementation difference, mode 2 is likely to yield different results across software.
Note
Blocks are named F1, F2, LL1, LL2 and WO in sequence. Two limiters are named VLIM and OLIM in sequence.

ST2CUT#
ST2CUT stabilizer model. Automatically adds frequency measurement devices if not provided.
Input signals (MODE and MODE2):
0 - Disable input signal 1 (s1) - Rotor speed deviation (p.u.), 2 (s2) - Bus frequency deviation (*) (p.u.), 3 (s3) - Generator P electrical in Gen MVABase (p.u.), 4 (s4) - Generator accelerating power (p.u.), 5 (s5) - Bus voltage (p.u.), 6 (s6) - Derivative of p.u. bus voltage.
(*) Due to the frequency measurement implementation difference, mode 2 is likely to yield different results across software.
Blocks are named LL1, LL2, LL3, LL4 in sequence. Two limiters are named VSS_lim and OLIM in sequence.
