PssIEEE4B
IEEE 421.5-2005 type PSS4B power system stabilizer. The PSS4B model represents a structure based on multiple working frequency bands. Three separate bands, respectively dedicated to the low-, intermediate- and high-frequency modes of oscillations, are used in this delta omega (speed input) PSS. There is an error in the in IEEE 421.5-2005 PSS4B model: the Pe input should read -Pe. This implies that the input Pe needs to be multiplied by -1. Reference: IEEE 4B 421.5-2005, 8.4. Parameter details: This model has 2 input signals. They have the following fixed types (expressed in terms of InputSignalKind values): the first one is of rotorAngleFrequencyDeviation type and the second one is of generatorElectricalPower type.
