Sažetak

This paper presents a Takagi-Sugeno (TS) synchronous generator unit model intended for application in an autotuning power system stabilizer. The model takes into account all three process variables that can affect synchronous machine dynamics regarding stability - beside usually used active and reactive power (P and Q) it includes also line reactance (xm). It is shown that the proposed model gives very good results in spite of simple third order local model used as the consequent part of the proposed TS structure. This makes the model appropriate for implementation on simple microprocessor platforms. Because P, Q and xm are included as TS model premises, it is enough to identify parameters of models in consequent part of TS model off-line. In this way possible numerical instability is avoided, which is common to adaptive PSSs that calculate controller’s parameters directly from on-line identified plant parameters.
