This database is composed of stator voltages and currents, field voltage and rotor position of a three-phase synchronous generator under resistive load. The data were acquired by means of two Tektronix MSO 2014B oscilloscopes with 4 channels each. Data were collected on 8 channels corresponding to phase voltages (Va,Vb,Vc), phase currents (Ia,Ib,Ic), field current of the generator (Ifd) and a pulse signal for angular position reference of the rotor (theta_m). For the simultaneous collection of the signals, a trip circuit was designed and implemented, the output of which was used as the triggering signal for the oscilloscopes. The synchronous generator was connected to a synchronous motor (Y-Y) and to a resistive circuit (18 units of 40W lamps) which served as loads. Voltage data were collected by means of a Keysight N2791 voltage probes; current data were collected using Tektronix A622 current tips. An PHCT203 optical key was used to collect rotor position pulse signal. The generator model is MOTROM M610-75-B-1K8-GS of 0.5 cv, 1800 rpm, 4 poles. The generator parameters obtained by means of physical bench tests were: Rs = 32.5 ohms (stator winding resistance) Rfd = 358.9 ohms (field winding resistance) Ld = 0.803H (direct axis stator inductance) Lq = 0.691H (quadrature axis stator inductance) Lls = 0.12H (stator winding leakage inductance) Lfd = 2.23H (field winding inductance) Vf = 64V (field voltage applied during the experiment, supplied by an regulated DC source) The database is composed by the following files of preprocessed data sampled at 10kHz in which the following variables are given, respectively, time, Va, Vb, Vc, Theta_r, Ia, Ib, Ic: 1) data0001.txt 2) data0002.txt 3) data0003.txt 4) data0001.csv 5) data0002.csv 6) data0003.csv Further, the database contains the following files of raw data: 1) T0001A.txt 2) T0001B.txt 3) T0002A.txt 4) T0002B.txt 5) T0003A.txt 6) T0003B.txt Each realization is contained in two files (suffixes A,B) and contain: Suffix A time CH1 (Va) CH1_peak (Va peak) CH2 (Vb) CH2_peak (Vb peak) CH3 (Vc) CH3_peak (Vc peak) CH4 (Theta_r) CH4_peak (Theta_r peak) Suffix B time CH1 (Ia) CH1_peak (Ia peak) CH2 (Ib) CH2_peak (Ib peak) CH3 (Ic) CH3_peak (Ic peak) CH4 (EMPTY) CH4_peak (EMPTY) When using the raw data, it is important to consider that the values were acquired in the following conditions: - Voltage probe scale: 100:1 - Current probe scale: 100mV/A - Oscilloscope probe scale: 10x - Oscilloscope configuration: check header of raw files.
