Analysis of power system small signal stability

Analiza EES-a pri malim poremećajima provedena je na primjeru IEEE mreže sa 9 sabirnica. Predstavljen je postupak modeliranja elemenata EES-a, linearizacija sustava, modalna analiza EES-a te naposlijetku primjer analize u programu PSS/E na spomenutoj mreži. Modeli elemenata EES-a uključuju sinkroni generator, uzbudni sustav, stabilizator sustava, pogonski sustav, turbinski regulator, model vjetroagregata tipa 3 i općenite modele potrošnje.Small signal stability of electrical power system is conducted on IEEE 9 bus grid. In this thesis, models of typical power system elements are derived including synchronous generator, excitation unit, power system stabiliser, prime mover unit, turbine regulator, model of the wind plant type 3 and various models for consumption. Proces of system linearization is derived and explained. Models with real parameters are implemented in PSS/E analysed
