“…The comparison of the simulated flux density function of time with the experimental data measured at site as shown in Figure 5 confirmed that the simulation results are in good agreement with the test data. Based on the obtained electromagnetic field solution at rated voltage no-load, the magnetic core losses of the generator are then computed based on the dynamic core loss mode in the time domain and given in (4).

Predictions of the different magnetic core losses with acceptable accuracy are key parameters for temperaturerise calculations for considered up-rate in large hydro electrical machines. In this paper, available core loss model is used to compute the electromagnetic core losses in large hydro electrical machine during no-load and short-circuit modes. The obtained results are discussed and compared with the available test data.

“…Usually short-circuit simulations are done with the objective of analyzing the stator and damper bar currents behaviour, as in [4]. In this specific paper, the transient operation of a salient pole synchronous generator during an inter-turn stator fault with different number of shortcircuited turns using FEM was investigated.…”

“…The formulas of the magneto motive force (MMF) and MFD are analyzed under normal condition and fault. The rules are revealed that FWISC mainly affects MMF but has a very little impact on the permeance per unit area (PPUA) [4] . In addition, the harmonic components of the parallel branch circuit on stator windings and air gap differential coil induction potential are analyzed [5] .…”

In order to study the impacts of the stator magnetic pull per unit area (MPPUA) characteristics under different field winding inter-turn short-circuit (FWISC) degrees in generator, comparative study of 3D numerical simulations and experiments are respectively taken to calculate the quantitative data of stator MPPUA by finite-element method (FEM) in this paper. Firstly, the nature exciting force of stator vibration, which is called MPPUA, is carried out. Then simulations data on MPPUA under normal condition and different short-circuit degrees are obtained. Finally, the variation rules of MPPUA characteristics by experiments under different conditions are studied. The results show that in normal condition the main harmonic components of MPPUA consist of only 6th-harmonic component. However, the occurrence of FWISC will bring in extra 1st, 2nd, 3rd, 4th and 5th-harmonic components to MPPUA. Meanwhile, with the increasing of the rotor short circuit degrees, the amplitudes of 1st, 2nd, 3rd, 4th and 5th-harmonic components will present an increasing trend. However, the amplitudes of 6th-harmonic component will present a decrease trend.
