摘　　要：在传统的配电系统中,北美地区所采用的电压等级一般为10 kV左右,相关的配电系统规划设计经验也较为丰富,但近年来20 kV配电系统逐渐得到电网企业的重视,业内对20 kV配电系统也有较为成熟的应用案例。为此,文章详细分析了20 kV配电系统规划设计的方法和步骤,并介绍了20 kV配电设计过程中有关变压器容量和导体截面积的选择方法。In the traditional distribution system,the voltage level used in North America is generally about 10 kV,and the related distribution system planning and design experience is also relatively rich,but in recent years,the 20 kV distribution system has gradually been paid attention by grid companies There are also mature application cases for the 20 kV distribution system.To this end,this paper analyzes the methods and steps of 20 kV distribution system planning and design in detail,and introduces the selection methods of transformer capacity and conductor cross-sectional area in the process of 20 kV distribution design.
