利用微电网提高垃圾填埋场清洁能源利用率

摘要

垃圾填埋场在国内分布广泛,蕴藏着丰富的清洁可再生能源.为了提高垃圾填埋场清洁能源利用率,提出建设微电网的方案.在对兴丰垃圾填埋场的现状进行分析后,构建了兴丰微电网的拓扑结构.首先以沼气发电机组及光伏发电为发电模块,并辅以储能电池,主要用户为垃圾填埋场渗滤液处理厂;然后分析了微电网内各组成部分的特性,合理配置各分布式电源的容量;最后对预期建设成果进行简要估算.结果表明该建设方案切实可行.%In order to improve use ratio of clean energy in the landfill,this paper presents the scheme for building the micro-grid.On the basis of analyzing situation of Xingfeng landfill,it constructs the topological structure of Xingfeng micro-grid. It firstly uses biogas power generators and photovoltaic power generators as generation modules by supplemented with energy storage batteries,and the main users are landfill leachate treatment plants. Then it analyzes characteristics of constitute parts inside the micro-grid so as to reasonably allocate capacities of distributed power sources.Finally,it evaluates expected construction achievements.Corresponding results prove feasibility of this scheme.
