Impedance modelling for European style Distribution Feeder

This paper discusses the methods of modelling a European style TT grounded low voltage (LV) distribution system without increasing computational complexity and with increased accuracy. The conventional Kron's reduction neglects the effect of the neutral current return path through the neutral conductor. While a four-wire model gives accurate power flow results with the possibility to monitor the neutral voltage, it also increases the computational burden. In this paper, a novel reduction method is proposed for European style TT grounded low voltage distribution systems to an equivalent three-wire system without neglecting the impact of the neutral voltage.
