Selected results of signal measurements in a ship power station with two generators working in parallel with the use of the Estimator/Analyzer instrument

Description

The presented dataset is part of research focusing on the assessment of metrological properties of the instrument,  Estimator/ Analyser (A/E v.2),  developed and made at the Faculty of Electrical Engineering, Department of Marine Electrical Power Engineering, of Gdynia Maritime University. The instrument performs a set of measurement functions that allow the assessment of the electrical power quality parameters. The attached dataset contains the measurement results carried out in a laboratory, using the physical model of a ship power station.

The measurement setup is shown in Fig. 1.

The dataset file contains data recorded in a marine power plant at a sampling rate of 25.0 kHz and presents in seven columns the samples relating to the instantaneous values of three voltages on the main bars and four currents measured for two generators (G1 and G2), sequentially:

  • samples related to the line voltage U12,
  • samples related to the line voltage U23,
  • samples related to the line voltage U31,
  • samples related to the G1 generator current in phase 1 (IG11),
  • samples related to the G1 generator current in phase 2 (IG12),
  • samples related to the G2 generator current in phase 1 (IG21),
  • samples related to the G2 generator current in phase 1 (IG22).

Voltage samples are expressed in V and samples relating to currents in mV.

To get the line voltage values from the respective samples, the voltage ratio of 150 [V/V] should be used.

To obtain the instantaneous values of the currents from the corresponding samples, the current probe ratio -20 [mV/A] must be used for the G1 generator samples, and -10 [mV/A] for the G2 generator (the “minus” sign means that the current flow direction has been corrected).

A measurement system based on NI PXIe-1062Q was used as a reference instrument.
