The voltage on bus bars of the main switchboard of the ro-ro ship electrical power system during a layover at the port
Description
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 carried out onboard a ro-ro ship during a layover at the port.
The ro-ro ship is equipped in three-phase, three-wire electrical power systems. The ship's electrical power plant consists of two free-standing generators 1000 kVA each and two-shaft generator 1500 kVA each (see Figure 1). The nominal voltage on bus bars of the main switchboard was 400 V with a frequency equal to 50 Hz. The single free-standing generator has been used during a layover at the port.
The voltage of 220V has been obtained by means of 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 2.
The files contain voltage waveforms of the output of a/d converters in [V], in three phases for 400 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 400 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: ro-ro_layover_the value of the mains voltage (400 or 220)_number of the set.
