基于运营难度系数的水电站标准化运营管理评价研究

Research on the Standardized Operation Management Evaluation of Hydropower Station Based on Operation Complexity

随着水电行业的不断深入发展,新水电开发愈加困难,加之能源高质量发展和电力体制改革的持续推进,都对存量水电管理水平提出了更高要求。现有水电运营评价体系难以对不同类型的水电站进行横向比较,以某省65家水电站为研究对象,将水电站运营差异性的量化表达为重点进行研究,创新性提出水电站运营难度系数概念,有效量化水电站运行难度,以更加全面、客观的反映已投产水电站的运营管理情况。围绕对标管理核心思想,通过水电不同重要程度特征属性的提取,利用随机森林回归、可拓学等理论与方法,开展基于水电站运营难度系数的对标评价研究。基于运营难度系数量化模型,输入评价集电站资料进行指标计算,结合信息熵赋权、改进可拓学方法得到评价结果,与企业自评估成果大致相符,结果表明研究提出的基于运营难度系数的对标评价办法具备合理性和较强的适应性,可为水电企业寻优补差工作的开展提供参考。

With the continuous in-depth development of hydropower industry,the development of new hydropower station is becoming more and more difficult.In addition,the high-quality development of energy and the continuous promotion of electric power system reform have higher requirements for the management level of existing hydropower stations.The existing operation evaluation system of hydropower station is unable to make a horizontal comparison among different types of hydropower stations,so this paper takes 65 hydropower stations in a prov⁃ince as the research object,focuses on the quantitative expression of operation differences of hydropower stations,and innovatively proposes the concept of operation difficulty coefficient of hydropower station to effectively quantify the operation difficulty of hydropower stations and reflect the operation and management of hydropower stations in operation in a more comprehensive and objective way.It centers on the core thought of benchmarking management to conduct a benchmarking evaluation research based on the operation difficulty coefficient of hydropower stations by extracting the characteristic attributes of hydropower stations with different importance degrees and using theories and methods such as random forest regression and extenics.Moreover,the paper quantifies the model based on the operation difficulty coefficient,inputs the data of power stations for index calculation,and combines information entropy weight and improves extenics method to get the evaluation results,which are consistent with the self-evaluation results of the enterprise.The results show that the proposed benchmarking evaluation method based on operation difficulty coefficient is reasonable and adaptable,and can provide a reference for the development of optimization and compensation of hydropower enterprises.
