Application of 20kV voltage level in mediumvoltage power distribution network

Abstract

Abstract: The 10kV voltage level was adopted basically for power supply in medium voltage power distribution network of some area. Along with the increasing of electric load density and the expanding of service area, the original power distribution network is not satisfy the needs for power supply. Development of 20kV voltage level power distribution network should bring notable benefit in reducing transmission losses and increasing transmission capacity. Based on theoretical analysis, combining with the pilot project of 20kV voltage level power distribution network in the city, the advantages and development prospect of 20kV power distribution network were demonstrated.

Key words: 20kV voltage level, medium voltage power distribution network, substation, transmission losses
