摘　　要：抽水蓄能电站施工供电系统建设面临用电负荷大、施工周期长、电源距离远、供电可靠性要求高的挑战。为有效评价施工供电系统方案的合理性,以石台抽水蓄能电站为例,基于AHP法和模糊理论,选取了8个一级评价要素、2个二级评价要素,建立了多层次的施工供电系统方案二级综合评价模型,有效克服了传统评估方法的定性化判断和单一化分析。分析结果表明,石台抽水蓄能电站施工供电系统方案一级、二级综合评价评分值均在0.7~0.9之间,经济性、可靠性、安全性评价较合理。研究可为类似工程施工供电系统方案定量评价提供有效的参考。The construction period of the pumped storage power station is characterized by high electricity load,long construction period,long power supply distances,and high reliability requirements of power supply.In order to evaluate the rationality of the power supply system plan,taking the Shitai Pumped Storage Power Station as an example,based on the AHP method and fuzzy mathematics theory,8 primary evaluation factors and 2 secondary evaluation factors were selected to establish a multi-level comprehensive evaluation model for the power supply system plan,which effectively overcomes the qualitative judgment and singular analysis of the traditional evaluation methods.The results show that the comprehensive evaluation scores for the primary and secondary levels of the construction power supply system of the Shitai Pumped Storage Power Station are both between 0.7 and 0.9,indicating that the economic,reliability,and safety evaluation of the power supply system plan is relatively reasonable.The study can provide an effective reference for the quantitative evaluation of similar construction of power supply system plans.
