分布式光伏发电在污水处理厂的应用案例及收益分析

Application Scheme and Revenue Analysis of Distributed Photovoltaic Power Generation in Sewage Treatment Plants

摘要: 基于污水处理作为能耗密集产业消耗大量电能的现状，本文以温岭市某污水处理厂分布式光伏发电方案为例，提出将分布式光伏发电应用于污水处理厂，从光伏组件倾角、方阵布设、发电量估算等方面进行设计要点介绍。同时，以25年为运行周期，对该污水处理厂运营期间产生的经济效益进行分析，综合每年利润率可达到14.24%左右。除此之外，该污水处理厂可实现节约土地资源、节约能耗等环境效益，积极响应“双碳目标”的实施。本研究为分布式光伏发电系统设计提供了数据指导和参考。

Abstract: Based on the current situation that sewage treatment consumes a lot of electricity as an ener-gy-intensive industry, this paper takes the distributed photovoltaic power generation scheme of a sewage treatment plant in Wenling City as an example, and proposes to apply distributed photo-voltaic power generation to the sewage treatment plant, and introduces the design points from the aspects of photovoltaic module inclination, square array layout, and power generation estimation. At the same time, taking 25 years as the operating cycle, the economic benefits generated during the operation of the sewage treatment plant are analyzed, and the comprehensive annual profit rate can reach about 14.24%. In addition, the sewage treatment plant can achieve environmental benefits such as saving land resources and energy consumption, and actively responds to the im-plementation of the “dual carbon goal”. This study provides data guidance and reference for the design of distributed photovoltaic power generation system.
