Abstract According to the feature that 20 kV power distribution system is better than 10 kV power distribution system，Xiang’an district of Xiamen city is selected as the pilot place for 20 kV voltage level and the status of 110 kV power grids and the above is analyzed and their long ?鄄 term loads are forecasted. The long?鄄term 110 kV network frames and the above in the district are planned and laid with 10 kV voltage level and 20 kV voltage level separately. By analyzing and comparing technical indicators such as the number and capacity of substations, economic benefit of power investment，substations land occupation and HV corridor，etc.，the advantage of   20 kV power distribution system is discussed.
