“…Thus, the channel is comparable with the in-vehicle channels of electric vehicles (EVs) [15], with the difference that the DC grid is longer in the LVDC. Moreover, as concluded in [13] and [14], the impulsive noise in the channel is cyclostationary with the period related to the mains cycle, including the impulses generated by the rectifier and CEI switchings (the LVDC system is connected to the 50 Hz MV grid and the customer AC network). This together with the rectifier and the CEIs as active components, acting as time-varying impedance terminations in the channel ends, leads to the fact that the LVDC channel is periodical similarly as the AC indoor channels [14], [16].…”

“…The narrowband PLC channel is studied, and the modems are tested in the LVDC laboratory setup and in the LVDC field grid presented in [13] and [14].

“…From the measured noise samples, noise PSDs are calculated with a Welch PSD estimate to obtain the noise PSDs. Because of the NB PLC modems, the duration of one data transmission packet is approximately 28 ms (with IP packet), and longer than with the HF band PLC modems studied in [13]. The measured noise sample is 40 ms containing two periods of a 50 Hz AC cycle.…”

It has been shown that high-frequency (HF) band power line communication (PLC) is a feasible data transmission method for a smart grid concept, namely for a low-voltage direct current (LVDC) electricity distribution system. However, because of the signal attenuation, the communication distances in the LVDC grid are limited with the HF band PLC. Hence, the new narrowband (NB) PLC should also be tested for the concept. In this paper, the PLC channel analysis in the LVDC system is carried out for the novel NB PLC technology, that is, the G3-PLC in the frequency band of 150-490 kHz. For the channel analysis, channel gain and noise signals from the terminals of the PLC couplers designed for the NB PLC are measured. The performance of the G3-PLC is analyzed theoretically and by communication tests. The noise voltages are measured, and communication tests are carried out in the LVDC laboratory system and in an LVDC field installation grid. The results show that NB PLC could be suitable for the concept. Keywords-Low-voltage direct current (LVDC); narrowband (NB); power line communication (PLC); smart grid (SG)
