Abstract
The paper explores the influence of a voltage-dependent local load on electromechanical oscillations of a synchronous generator. The analysi s is performed with different generator models, both with and without control devices. The classical static-load models were used as well as a generic model of dynamic load. It is shown that a voltage-dependent load can influence the damping of the electromechanical oscillations and thus the overall stability of the generator. This influence is ver y dependent on load parameters and on the generator's parameters and o perating conditions. It is also shown that the use of dynamic-load mod els instead of static can have a significant influence on the evaluati on of the total effect that voltage-dependent loads have on electromec hanical oscillations of the generator.
