Jv. Milanovic et Ia. Hiskens, OSCILLATORY INTERACTION BETWEEN SYNCHRONOUS GENERATOR AND LOCAL VOLTAGE-DEPENDENT LOAD, IEE proceedings. Generation, transmission and distribution, 142(5), 1995, pp. 473-480
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.
