Description of the research topic:
"Strict requirements were established on the voltage quality of the electric supply network in the last decade. One of these requirements is in connection with the harmonic distortion of the voltage.
The electric consumers can be divided into two groups:
•linear loads: If the voltage is sinusoidal, they are consuming sinusoidal current.
• nonlinear loads: In case of sinusoidal voltage their current is non sinusoidal, the spectrum consists harmonic components.
The voltage distortion is caused by the non-linear loads connected to the network on different voltage levels. This distortion could cause faults both in the high power energy system and the parallel telephone lines. The non-linear loads act as virtual harmonic current generators. Utility companies can refuse consumers to be connected to the network injecting high current harmonics. In these cases consumers are interested in installing harmonic filters to reduce the distortion they are causing.
The main goal of this research would be developing a universal model for LV (and MV) consumers for predicting the effect on the upstream network, confirming the applicability of the standard."
