. The paper focuses on the investigation of low voltage direct current (LVDC) power distribution network harmonic content. For investigation electromagnetic transient simulation environment PSCAD/EMTDC is used. In the paper, the frequency content of voltages and currents in the LVDC network is presented. Dependence on the power quality of the feeding medium voltage (MV) network of the LVDC network configuration is shown and discussed. In addition, impact of distribution of load across bipolar DC network load on MV network power quality is considered. Model of the LVDC power distribution network is created in PSCAD/EMTDC environment to carry out the above mentioned analyses.
