摘　　要：针对抽水蓄能电站的功能特点,提出了"辅助服务效益"的概念,建立了由财务评价、国民经济评价及辅助服务效益组成的经济效益指标体系。首先应用改进的序关系分析法确定各指标的权重值,将点赋值推广为区间赋值,从整体上提升了评价效果。然后选取非线性方法无量纲处理定量指标,三角模糊数法量化处理定性指标,最终线性加权得到各指标的综合评价值。根据某抽水蓄能电站的部分实际参数计算相关评价指标,对算法的适用性及评价的逻辑性进行了验证。研究结果可为全面评判某抽水蓄能电站的经济效益提供参考。In view of the functional characteristic of pumped storage power plant,the concept of“auxiliary service benefit”is put forward,and the economic benefit index system of pumped storage power plants composed of financial evaluation,national economic evaluation and auxiliary service benefit is established.Firstly,the improved order relation analysis method is employed to determine the weight value of each index,and the point assignment is extended to interval assignment,hence improving the overall evaluation result.Subsequently,the quantitative indexes are processed dimensionless by non-linear method,and the qualitative indexes are quantified by the triangular fuzzy number method.Finally,the comprehensive values of the evaluation indexes are obtained via linear weighting.The applicability of the present method and the logic of the evaluation are verified through a practical case.
