居民住宅小区供电的实施方案

Implementation Scheme of Power Supply in Residential District

居民住宅小区的用电负荷变化很大,用电高峰时,变压器近乎处在满载下运行,低谷时,又处在近乎空载下运行,变压器的有功和无功的功率损耗很大。为降低这部分功率损耗,介绍一种根据实际用电负荷来自动调整变压器的运行台数改变运行容量的方法,以满足用电负荷变化的需求,使变压器基本处在负荷经济点上运行。

The residential quarters ,of the electricity load changes greatly. The high demand for electricity is almost at full load running of transformer,while trough is in ahnost no load transformer operation,active power and reactive power loss are very big. In order to reduce the power loss of this part, this paper introduced the method of changing the transformer operating capacity. According to actual electrical load, the operation quantity of transformer is adjusted automatically to meet the variational demand of electricity load, which makes the transformer operate at an economic point.
