PssIEEE2B

Class Description

IEEE 421.5-2005 type PSS2B power system stabilizer model. This stabilizer model is designed to represent a variety of dual-input stabilizers, which normally use combinations of power and speed or frequency to derive the stabilizing signal. Reference: IEEE 2B 421.5-2005, 8.2.
