农家院旅游景区配电网改造方案研究

On the Reform of Power Grid for Farmyard Tourist Areas

天津近郊某地区,随着政府对景区的不断开发,当地旅游经济在近年取得飞速发展,供游客旅游住宿的农家院数量及规模逐年扩大,用电需求量大幅增加。该地区除存在传统农村电网共性问题外还存在如农家院用户用电报装信息不实,亦或是经过房屋加盖改造,原有信息未及时得到更新,导致无法准确估算台区负荷增长情况;电力改造无法跟上农家院建设速度,用电高峰期配电变压器过载严重;农家院用电负荷峰谷差较大;用电负荷不均,变压器三相不平衡等诸多问题,本文针对发现问题将开展具体研究。

The continuous development of scenic regions promoted by the local government has achieved remarkable results for a suburb district of Tianjin, which also has caused the increase of the power demand due to the growing number and scale of the tourist accommodation farmyard. That apart from some common ones, there are also problems such as faulty reported information on users’ power installation, original information not getting updated in time after house renovation, which make it almost impossible to deliver an effective forecast on the power load growth in these areas. Additionally, power reconstruction cannot keep up with farmyard construction;distribution transformers are overloaded during the peak season;the peak-valley load difference of the farmyard power consumption is excessive;power load is uneven and transformer three-phase imbalance is getting serious. This thesis is aimed at conducting an analysis on the problems with the power network reconstruction and attempt to provide certain solutions.
