Resumé

This paper proposes a new method to detect loss
of field (LOF) phenomenon in synchronous generators. The
presented method employs the exciter output voltage and
current signals to calculate the DC power injected into the
generator field circuit. It is shown that any LOF failure in the
field circuit, interrupt the DC power delivery to the rotor
winding so that by selecting simple settings for the scheme,
such interruptions are easily detected. To evaluate the
proposed scheme performance, simulation studies are carried
out by using the phase domain (PD) generator model available
in the real-time-digital-simulator, while the PD model allows
simulating different realistic LOF failures. Obtained results
show that the proposed scheme can easily detect different LOF
failures.
