【摘要】：从生态环境角度来讲，垃圾是污染物，但从资源方面看，垃圾是一种很有前景的可再生资源。利用垃圾作为燃料来进行发电，不但清理了工业生活垃圾，，也满足了电量不足，为社会分担了一定的发电压力。其中，垃圾发电厂的选址直接关系到了整个垃圾发电厂以后的发展，有时会因为垃圾发电厂的选址引起社会问题并影响发电厂的建设。论文首先分析了垃圾发电厂选址存在的问题，提出了垃圾发电厂选址的目标和原则，并阐述了垃圾发电厂选址的步骤。然后，介绍了模糊认知图模型的理论和方法，分析影响垃圾发电厂选址的因素，建立了动态的因素影响模型，并确定了因素之间因果影响程度值的计算方法。最后，介绍了多目标优化模型的基本理论，在一定的假设条件下，从影响垃圾发电厂选址的技术、经济、环境和社会四个方面，分别建立子目标函数，确定了约束条件，再把模糊认知图模型与多目标优化模型结合起来，建立了最终的选址模型。运用该模型计算垃圾发电厂选址的位置，并以秦皇岛环保垃圾发电项目的相关数据为基础，运用效用函数的求解方法将多目标优化问题转化成单目标的优化问题，计算出了秦皇岛市垃圾发电厂的建厂位置，并与秦皇岛环保垃圾发电项目的拟建厂位置进行了对比分析。说明了本文垃圾发电厂选址方法的可行性。
[Abstract]:From the ecological point of view, garbage is a pollutant, but in terms of resources, garbage is a promising renewable resource. Using garbage as a fuel for power generation not only clears industrial waste, but also satisfies the shortage of electricity. The site selection of the refuse power plant is directly related to the development of the whole refuse power plant, sometimes it will cause social problems and affect the construction of the power plant because of the location of the waste power plant. Firstly, the paper analyzes the problems existing in the site selection of garbage power plants, puts forward the objectives and principles of the site selection of the waste power plants, and expounds the steps of the site selection of the waste power plants. Then, the theory and method of the fuzzy cognitive graph model are introduced. This paper analyzes the factors influencing the location of garbage power plant, establishes the dynamic factor model, and determines the calculation method of the degree of causality between factors. Finally, the basic theory of the multi-objective optimization model is introduced. Under certain assumptions, the sub-objective function is established from the four aspects of technology, economy, environment and society that affect the location of garbage power plant, and the constraint condition is determined, and then the fuzzy cognitive map model is combined with the multi-objective optimization model. The final location model is established, which is used to calculate the location of garbage power plant, and based on the related data of Qinhuangdao environmental protection garbage power generation project. The utility function method is used to transform the multi-objective optimization problem into a single-objective optimization problem, and the location of the waste power plant in Qinhuangdao City is calculated. The location of the proposed plant is compared with Qinhuangdao environmental protection refuse power generation project, and the feasibility of the site selection method of the garbage power plant in this paper is explained.
