This paper presents a comparative analysis of the impact of the forced excitation coefficients of two different excitation control systems of large synchronous generators on the transient stability of electric power systems. The analysis is based on the mathematical model of the synchronous generator of the seventh order based on Park’s transformations and a simplified and sufficiently accurate model of excitation control systems. The model simulates the operation of the generator unit as a one-machine system connected to the infinite bus through a double transmission line during a normal operating regime followed by a short circuit fault disturbance causing challenging the transient stability of the system.

W artykule przedstawiono analizę porównawczą wpływu współczynników wzbudzenia wymuszonego dwóch różnych układów regulacji wzbudzenia dużych generatorów synchronicznych na stabilność przejściową systemów elektroenergetycznych. Do analizy wykorzystano model matematyczny generatora synchronicznego siódmego rzędu oparty na transformacjach Parka oraz uproszczony i wystarczająco dokładny model układów sterowania wzbudzeniem. Model symuluje pracę agregatu prądotwórczego jako systemu składającego się z jednej maszyny podłączonej do nieskończonej magistrali za pośrednictwem podwójnej linii przesyłowej podczas normalnego trybu pracy, po którym następuje zakłócenie zwarciowe, powodujące wyzwanie dla przejściowej stabilności systemu.
