摘　　要：结合河南省部分地区典型小区配电变压器的特点,首先对户均配变容量的影响因素进行分析,在充分调研不同典型小区居民负荷特性的基础上,对居民负荷及用户数进行预测;之后确定了典型居民小区的配变容量的选取,并对配电变压器的经济运行区间进行分析;最后对典型居民小区现有的配变容量进行了优化,并对配电变压器的投资进行了经济效益分析、敏感性分析等。提出了配变容量优化方案。This paper considers with the characteristics of typical residential distribution transformers in some areas of Henan Province.Firstly,this paper analysises the influence factors of average capacity of the distribution transformers;based on the full investigation of the different typical residential load characteristics,the residents load and the number of consumers is predicted;Then it determines distribution transformers capacity selection of the typical residenteial area,and analyzes the economic operation interval of the distribution transformers.Then the existing distribution transformer capacity in typical residential area is optimized.Finally the the economic benefit and sensitivity of the investment of distribution transformer is analysised.In this paper,the optimized scheme of distribution capacity is put forward.
