| 当前已有调容变压器配置评估方法中存在着考虑因素单一、综合成本考虑不充分以及缺乏台区运行控制结果分析等问题。对此文中提出了一种综合考虑台区运行控制与经济性提升的调容变压器配置评估方法。首先基于二阶锥规划构建了潮流模型，通过台区优化运行控制结果得到典型日净负荷数据，作为调容变压器容量选取的基础数据。其次分析了影响调容变压器配置评估的多维关键因素，然后建立了面向经济性提升的综合成本评估指标。最后依据典型台区历史负荷数据，开展调容变压器配置算例分析。在考虑光伏(photovoltaic, PV)接入和不考虑PV接入的两种场景下，基于不同运行规划周期和容量裕量，通过与传统变压器配置方案进行对比，验证了文中所提调容变压器配置方案的有效性和优越性。 |

| Current methods for configuring adjustable capacity trans-formers have several limitations. These include limited con-sideration of influencing factors, insufficient integration of comprehensive cost analysis, and the absence of assessment based on distribution transformer area operation and control results. To address these issues, this paper proposes a config-uration evaluation method for adjustable capacity transform-ers that integrates operational control and economic perfor-mance. First, a power flow model is built using second-order cone programming. Based on the optimized operation of the distribution area, typical daily net load data are obtained to support capacity selection of adjustable capacity transformers. Then, key factors affecting configuration decisions are analyzed, and a comprehensive cost evaluation index is developed. Case studies using historical load data are conducted under both photovoltaic (PV) and non-PV scenarios. By comparing different planning periods and capacity margins with traditional configurations, the effectiveness and ad-vantages of the proposed method are demonstrated. |
