Deformation of voltage and current waveforms of synchronous machine on pulling out of synchronism

Original language description

By the test measurement of effect of pulling out of synchrnism of synchronous machines with salient poles on the electrical power network and synchronous machine was be detect existence of curves deformation of induction voltage. The curves are in all phases deformed with 3.th harmonics of voltage, whose common action forms noncircular vector of voltage betwen null point of electrical power network and null point of synchronous machine winding. If there are these null points connected, is generated thecirculating current surge, that as flowing through the null conductor with frequencies 150 Hz and with amplitude equal to sum of all phases current. Time lag the 3.th harmonic of phase voltage is defined by load angular size. On the pulling out of synchronism is chanced the position ot this 3.th harmonic in face of fundemental harmonic. Per this is possible observe pole instantaneous position.

Czech description

Při zkušebním měření vlivu výpadku synchronního stroje s vyniklými póly ze synchronismu, byla zjištěna přítomnost deformace indukovaného napětí 3. harmonickou ve všech fázích, jejichž společným působením vzniká netočivá složka mezi nulovým bodem synchronního generátoru a nulovým bodem sítě.
