Abstract：In the context of rapid urbanization,the demand for electricity capacity in newly built residential communities has been huge in the last two decades. With Chongqing as an example,the construction progress of 110 kV substations in each district fails to meet the demand of project construction and the planned substation capacity falls short of the demand for electricity use,making many newly built residential communities and businesses have no access to power supply nearby(within 3 km),or access to power supply only at 10 km away,which go against the national policy of energy conservation and emission reduction;a specific residential project in a region is used as an example to calculate the electricity demand by each standard,the actual electricity consumption of a well‑off model community is analyzed,and a solution is proposed to cope with the conflict between the electricity demand and power development.

摘　要：目前我国处于快速城镇化发展阶段，近二十年来不断建设的住宅小区用电容量需求很大，以重庆市为例，各区域110 kV变电站的建设进度跟不上该区域项目建设需求，且规划的变电站容量也跟不上项目建设的用电需求，导致很多新建住宅小区和商业不能就近（3 km范围内）取得电源，甚至有些项目需要在10 km以外去获取电源，不符合国家节能减排的发展政策；以某区域具体住宅项目为例，按各标准计算用电需求，并分析某小康示范小区的实际用电量，以及某两个110 kV变电站实际运行负荷图，最终提出应对用电需求与电力发展矛盾的解决方案。
