摘要: 某地区中压配电网主要采用10kV供电,随着电力负荷密度和供电范围的增大,原有10kV配电网已无法满足需求,发展20kV等级供电网络在降低网损、增大输送容量等方面效益明显。通过理论分析并结合该市20kV电压等级供电网的试点工程,论证了20kV中压配网的优越性和发展前景。

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.
