Application of Single-Phase Distribution Technology and Analysis of Energy-Saving Effect

Single-phase distribution approach is a new low-voltage power distribution technology. It is significant for reducing distribution line losses, improving power supply reliability and assuring voltage quality. RMS current method is adapted. In a typical residential community, distribution transformer loss, low voltage line loss and investment in equipment single-phase and three-phase distribution methods is calculated, compared and analyzed. It is proved that the full extension high-voltage power line is an effective means to reduce the running loss. And Single-phase power distribution method has good economic and social benefits, which can be adapted and promoted according to the local conditions.
