The voltage on bus bars of the main switchboard of the car carrier electrical power system at sea trials during a sea voyage

Opis

The dataset is part of the research results on the quality of supply voltage on bus bars of the main switchboard of the ship's electrical power system in different states of ship exploitation. The attached dataset contains the measurement results conducted onboard the car carrier at sea trials. The data were recorded during a sea voyage, under normal operating conditions of the system, and when the vessel was drifting.

The car carrier is equipped in a three-phase, three-wire electrical power system. The ship's electrical power plant consists of six free-standing generators of 1500 kVA each. The nominal voltage on bus bars of the main switchboard was 3300 V and 440 V with a frequency equal to 60 Hz. The voltage of 220V has been obtained using a transformer.

The voltage waveforms on bus bars of the main switchboard were recorder with the digital measuring system, which allows the simultaneous measurement of three phase-to-phase or two-phase voltages. The initial conditioning of the input signals is carried out by optoisolation amplifiers and a low-pass filter module (antialiasing). The formation of the output digital signal from the analog signal takes place in the a/d converter with a resolution of 16 bits and a sampling rate of up to 20 kS/s. Using three channels at the same time allows the maximum sampling rate of 6.6 kS/s. The block diagram of the digital measuring system is shown in Figure.

The files contain voltage waveforms of the output of a/d converters in [V], in three phases for 440 V and 220V networks. The attenuation and offset of the measuring path for the 220 V network are 77.6398 [V/V] and -0.017 V, respectively. For the 440 V network, the attenuation and offset of the measuring path are equal to 134.0123 [V / V] and -0.0175 V, respectively. The sampling frequency is inserted in the first row of the attached files.

The files are described as follows:
car_carrier_voyage_the value of the mains voltage (440 or 220), these files contain measurement data that was recorded during a sea voyage.
car_carrier_drift_220_number of channels, these files contain measurement data that was recorded when the vessel was drifting.
