【摘要】：随着我国电力企业电力负荷与日俱增,尤其是日间负荷更是增长迅速,于是造成用电峰谷差越来越大。为缓解电力系统的高峰与低谷之间供需落差的问题,因而产生了抽水蓄能电站,它是电力系统调峰运行的重要保证。资产全寿命周期管理是抽水蓄能电站在新能源、新发展形势下实现企业全面协调、可持续发展的战略要求。探索资产全寿命周期管理在抽水蓄能电站的资产管理模式中的优势,确定资产管理的重点内容,提出抽水蓄能电站资产全寿命周期管理评价指标体系与模糊综合评价模型,为抽水蓄能电站建立全面、协调的资产全寿命周期管理体系奠定基础。本文以抽水蓄能电站的资产全寿命周期管理评价为研究对象,首先介绍了抽水蓄能电站生产方式和资产经营方式,对抽水蓄能电站的资产特点及资产管理现状进行了分析,并阐述了资产全寿命周期管理理论的基本思想与涵盖了管理体制、管理机制、管理办法和管理手段的实施策略;其次,通过研究管理指标体系的设计方法,包括指标设计原则、指标获取途径、指标设置方法和指标数据的标准化处理,从而建立了抽水蓄能电站资产全寿命周期管理的评价指标体系,包括规划计划阶段指标、采购建设阶段指标、运行维护阶段指标以及退役处置阶段指标共计25项指标;再次,根据层次分析法的原理及其建模步骤,对抽水蓄能电站资产全寿命周期管理过程中的各指标权重进行了设计和定义,建立了包括四层的递阶层次的结构模型,并且通过向专家发放征询意见表,获得各级指标的判断矩阵,通过确定相对权重系数和一致性检验计算出了权向量W,从而计算并列出评价指标总排序权值计算结果,即各个指标相对于最高层的相对重要性指标;接着,阐述了对抽水蓄能电站资产全寿命周期管理进行评价的方法和步骤,根据已确定的管理指标权重进行单因素评价,即分别对定性指标和定量指标的隶属度进行确定,对于定量指标的隶属度计算采用模糊数学方法推求,即用最大、最小隶属函数模型,来模拟部分定量指标的隶属函数曲线;定性指标隶属度的推求采用模糊统计法,计算出多层次模糊综合评价结果。最后,按照上述方法和步骤针对某抽水蓄能电站进行了实例研究,即对其资产全寿命周期管理进行了多层次模糊综合评价,评价结果表明本文所确立的评价体系是可行有效的,并对该抽水蓄能电站资产全寿命周期管理评价结果中体现的缺陷和不足提出了改进的措施和对策,为今后该抽水蓄能电站资产全寿命周期管理的提升指明了方向。论文的研究成果对于抽水蓄能电站的资产全寿命周期管理评价提供了参考和依据。
[Abstract]:With the development of electricity power load in our country especially the day more grow with each passing day, the load is increased rapidly, thus resulting in more electricity peak valley difference between peak and trough. More and ease the power system of supply and demand gap, resulting in a pumped storage power station, it is important to ensure the power system peak load operation. The whole life cycle asset management is pumped storage in new energy power plants, realize the comprehensive coordinated development of enterprises in the new situation, the strategic requirements of sustainable development. To explore the advantages of life cycle asset management in pumped storage power plant asset management mode, determine the key contents of asset management, put forward the evaluation index system of pumped storage life cycle the management of power plant assets and fuzzy comprehensive evaluation model of pumped storage power station for the establishment of a comprehensive, lay the foundation for life cycle management system of coordination of assets. Based on Pumped Storage Power Station The life cycle management of assets evaluation as the research object, first pumped storage power station production and asset management mode is introduced, analyzed the current situation of asset characteristics and asset management of pumped storage power plant, and expounds the basic idea of asset life cycle management theory and covers the management system, management mechanism, strategy management ways and means of management; secondly, through the study on the design method of management index system, including index design principles, index acquisition approach, standardized processing index setting method and index data, and establishing the life cycle management of pumped storage power plant asset evaluation index system, including the planning stage index, procurement and construction stage index, operation and maintenance stage index and disposal stage index of a total of 25 indicators; thirdly, according to the principle of analytic hierarchy process and modeling steps of The weight of each index of pumped storage power assets life cycle management in the design and definition, including the establishment of the hierarchical structure model of four layers, and through to the expert issued advice table, obtain the judgment matrix of indicators at all levels, by determining the relative weight coefficient and consistency test to calculate the weight vector W, to calculate and list the evaluation index total rank weights calculation results, namely each index relative to the index of relative importance top; then describes the methods and steps of evaluation of pumped storage power plant asset lifecycle management, single factor evaluation according to weight management indicators have been identified, namely the membership of the qualitative and the quantitative indicators were determined for membership quantitative index calculation by using the fuzzy mathematics method to derive the maximum, i.e., the minimum membership function to simulate the model. Membership function curve of some quantitative indicators; for qualitative index membership degree of fuzzy statistics, calculate the multi-level fuzzy comprehensive evaluation results. Finally, according to the above methods and steps for a pumped storage power station is studied, which is on the whole life cycle management of the assets of the multi-level fuzzy comprehensive evaluation, evaluation the results showed that the establishment of the evaluation system is feasible and effective, and the pumped storage power plant life cycle asset management evaluation results and put forward the measures to improve the defects and deficiencies in the future for the pumped storage power indicates the direction of the life cycle management of power plant assets to enhance the research results of this paper provide. The reference and basis for the evaluation of life cycle management of pumped storage power plant assets.
