居民台区供电方案选择及其运行方式探讨

在分析居民台区负荷特性的基础上,综合考虑负荷增长、配电变压器运行损耗、投资成本以及资源有效利用,提出了大小配电变压器配合运行的居民台区供电方案及其运行方式安排,计算了运行损耗成本,并对现行方案和该方案的经济性进行了比较。实例结果表明：该方案在成本费用节约上优于现行居民供电方案,为供电公司在居民台区供电方案选择上提供一定的参考价值。

Study on power supply scheme selection and operation mode arrangement of residential district

Based on the analysis of residential district’s load characteristic, considering comprehensively load growth, distribution transformer’s operation loss, investment cost and efficient utilization of existing resources, this paper proposes a residential district’s power supply scheme and its corresponding operation mode arrangement in which distribution transformer with large capacity and that with small capacity operation coordinately, calculates operation loss cost and makes an economic comparison between the existing scheme and the proposed one. The results of the example demonstrate that the proposed scheme is superior to the existing scheme in cost saving. The work in this paper provides a certain reference value for power supply companies in selecting residential district’s power supply scheme.
