抽水蓄能电站技术经济效益指标体系综合评价研究

Study on comprehensive evaluation of tech-economic benefit index system of pumped storage hydropower station

为更科学合理地对抽水蓄能电站的技术经济效益进行综合评价,依据其技术经济效益特性选取了由运行效果、功能效益、财务效益和环境效益组成的指标体系。将改进型序关系分析法与熵权法结合,采用改进型序关系分析法确定主观权重、熵权法确定客观权重,并运用物元分析法建立综合评价模型,计算抽水蓄能电站技术经济效益的评价等级。根据某抽水蓄能电站的相关资料,采用定性和定量结合的方法来量化处理评价指标,建立相关评判标准,最终得到其技术经济效益综合评价等级。结果表明该电站技术经济效益大部分指标达到了预期,验证了该评价模型的适用性和有效性。通过研究结果分析得出该电站有待加强指标和已经达到标准的指标,便于有针对性采取相应措施提高电站技术经济效益,对今后电站的技术经济发展具有借鉴意义。

In order to more scientifically and reasonably carried out the comprehensive evaluation of the tech-economic benefit of pumped storage hydropower station,the index system composed of operational effect,functional benefit,financial benefit and environmental benefit is selected according to its tech-economic benefit characteristics. Combined the improve method of sequence relation analysis with entropy weight method,the subjective weight is determined with method of sequence relation analysis and the objective weight is determined with entropy weight method,while the evaluation grade of the tech-economic benefit of pumped storage hydropower station is calculated through establishing a comprehensive evaluation model with matter element analysis method. Based on the relevant data of a pumped storage hydropower station,the evaluation indexes are quantifiedly processed with the qualitatively and quantitively combined method,and then the relevant evaluation criteria are established,thus the comprehensive evaluation grade for its tech-economic benefit is obtained at last. The result shows that most of the indexes of the tech-economic benefit of the hydropower station reach to their expected targets,while the applicability and effectiveness of the evaluation model are verified. Through the analysis on the study result,both the indexes to be strengthened and the indexes those reach the relevant criteria of the hydropower station are obtained,which are not only convenient for targetedly taking the corresponding measures to improve the tech-economic benefit of the hydropower station,but also have referential significances for enhancing its techeconomic development in the days to come.
