摘　　要：针对配电变压器并列经济运行时可能会伴随供电可靠性降低从而可能导致的停电损失问题,提出了一种计及可靠性的变压器并列经济运行区间划分方法。将变压器的可靠性转化为一经济指标即可靠性成本加以体现,提出了包含变压器综合损耗引起的网损费用和可靠性成本的综合运行成本的概念,以综合运行成本最低来进行变压器并列经济运行区间的划分。最后通过算例分析验证了该方法的合理有效性,可供相关电力部门制定配电变压器经济运行方案参考。An optimal method of reliability-based economical operation for the transformers in parallel in a distribution network is proposed to minimize the transformer operation cost and to reduce the lost due to outage. This method turns the reliability item into an economic index for comprehensive cost calculation and description of the consequential cost caused by supply interruption. The optimal transformer economical operation zones are determined by minimizing the comprehensive operation cost, which consists of reliability cost and transformer operation costs. The effectiveness of the method is verified by two transformers in parallel with/without same capacity in a distribution network. This study may provide reference for making economical operation schemes of transformers in real distribution systems.
