摘要
针对目前配电变压器运行中存在的问题,制定简便易行的准则对其各项指标进行评价;判断筛选出的配电变压器是否具有改造实施风险,对没有实施风险的变压器分3部分进行改造。改造措施包括更换老旧变压器、对高负载率的变压器进行增容等。分析认为,满足每部分约束条件的投资效益比最小的方案为该部分的最优改造方案,各部分最优方案组成整体最优方案。以某线路为例,应用该方法确定其配电变压器的改造方案。结果表明,该方法可以有效降低线损,提高设备的运行水平。
For solving diseconomy problems in distribution transformers reconstruction,simple and practical criterions based on the actual situation are developed to judge the various parameters of distribution transformers.The distribution transformers selected without construction risks are divided into 3 parts and the reconstruction measures include replacing for new energy -saving distribution transformers,and increasing the capacity for high-load rate transformers.For each part of the distribution transformers, the reconstruction scheme under constraints with the least ratio of investment and efficiency is optimal.The overall optimal scheme is composed of each optimal scheme.A certain line in a certain area is taken as example.Distribution transformer reconstruction schemes are developed using the method.The computed result indicates that the method can reduce line losses effectively and increase operation level of equipment.
