【摘要】：近年来,随着一次能源的消耗加剧,节能已成为企业发展的核心问题之一。其中我国由于经济发展的刚性需求所致,火电成为一次能源的消耗大户。火电厂节能问题凸显。目前大多数火电厂在节能方面都进行了技术革新和管理改革,通过多种节能技术和措施,提高火电厂的节能水平。妈湾电厂以技术进步为先导,采用的节能措施具有多样性和复杂性,伴随而来的就是缺乏妈湾电厂节能综合评估方法的问题,因此,研究一种全方位评估妈湾电厂节能效果的模型和方法具有重要的现实意义。本文首先研究了序关系分析法,建立了递阶层次结构,阐述了目标层、标准层和方案层逐层计算的求解方法,形成了序关系分析法评估流程,并分析序关系分析法在电厂节能领域的适用性：其次介绍了妈湾火电厂基本信息,分析了妈湾火电厂的综合情况,从宏观、经济、生产、能源方面分析了妈湾电厂的运营及节能措施及方法,在此基础上,将节能指标分类,形成一个核心指标拓扑展开的节能评估指标体系,体系涉及运行节能、技术节能和管理节能三个方面的内容,节能评估指标由核心指标和拓扑展开构成；再次建立基于序关系分析法的妈湾电厂两级节能评估模型,并阐明二级和一级节能模型的具体评估方法,其中二级评估基于序关系分析法得出各分项的评估量化数值,一级评估赋予二级评估结果优化权重得出综合节能的评估量化数值；最后对妈湾电厂近年节能项目及具体方案进行评估,评估不同时间段,不同侧重面的具体节能项目,分析评估结果并提出今后妈湾电厂节能工作建议。通过理论分析和妈湾电厂节能方案的具体评估,验证了基于序关系分析法的节能评估方法的适用性和可行性,该方法可用于电厂节能的综合评估,并作为电厂建设和设计规划的参考依据。
[Abstract]:In recent years, with the consumption of primary energy increasing, energy saving has become one of the key problems of enterprise development in our country. Due to the economic development of the rigid demand, power consumption becomes a prominent problem. The energy saving in thermal power plant. At present most power plants in such aspects of technological innovation and management reform. Through a variety of energy-saving technologies and measures to improve the energy efficiency of thermal power plants. Mawan Power Plant to technological progress as the guide, the energy saving measures with diversity and complexity, is associated with the lack of a comprehensive assessment of Mawan Power Plant energy-saving methods, therefore, research on a comprehensive evaluation model and method of Mawan Power Plant energy saving the effect has important practical significance.
This paper studies the order relation analysis method, establishes the hierarchical structure, expounds the calculation method of standard target layer, layer and layer by layer, forming the order relation analysis method in the evaluation process, and analyze the applicability of order relation analysis method in power plant energy saving field, secondly introduces the basic information of Mawan Power plant the analysis, Mawan Power Plant comprehensive situation, from the macroscopic, economic, production, energy analysis of Mawan Power Plant operation and energy saving measures and methods, on this basis, the energy-saving index classification, the formation of energy-saving evaluation index system is a core index of topological unfolding, system involves three aspects of energy saving, energy saving technology and management of energy saving, energy saving evaluation index by the core index and topology structure; re established evaluation model of rank correlation analysis in Mawan Power Plant, saving two on two and clarify the primary and secondary section Specific assessment methods to model, the two level evaluation order relation analysis method based on numerical quantitative evaluation of each item, to assess the level of grade two gives numerical evaluation of quantitative evaluation results to optimize the weights of comprehensive energy saving; finally, to evaluate the Mawan Power Plant in energy saving projects and the specific evaluation scheme, different time, different the specific energy conservation projects, analysis of the results of the evaluation and put forward the future of Mawan Power Plant energy-saving work suggestions. Through theoretical analysis and specific assessment of Mawan Power Plant energy conservation program, verify the feasibility and applicability of such order relation analysis method based on the evaluation method, this method can be used for the comprehensive evaluation of energy saving in power plant, and as a power plant construction and planning and design reference.
