浅析光伏发电技术在废弃矿山中的应用

Application of photovoltaic power generation technology in abandoned mines

由于矿产资源枯竭,大多数矿山通常被遗弃和无人看管,造成严重的社会问题,阻碍这些地区的可持续发展。采矿业最近引进了可再生能源系统来解决这些问题。这项研究评估了废弃尾矿坝的光伏发电潜力。区域遮阳分析和现场调查表明,安装光伏系统的可用面积为44,220平方米。考虑到光伏阵列的可用空间,系统的设计容量为3MW。通过在系统顾问模型软件中输入每小时的天气数据、系统设计数据和现场评估数据,模拟发电过程。仿真结果表明,每年可产生3509MW时的电量。此外,经济可行性分析,假设20年的项目周期,确认光伏系统的净现值为1,903,000元。因此,在上东矿山尾矿坝上安装3 MW光伏发电系统是可行的,可为矿山废弃地的可持续发展提供有效的选择。

Due to the depletion of mineral resources,most of the mines are usually abandoned and unattended,causing serious social problems and hindering the sustainable development of these areas.The mining industry has recently introduced renewable energy systems to solve these problems.This study evaluates the photovoltaic power generation potential of the abandoned tailings dam.Regional shading analysis and field investigation show that the usable area for Installing Photovoltaic system is 44220 square meters.Considering the available space of PV array,the design capacity of the system is 3MW.By inputting hourly weather data,system design data and on-site evaluation data into the system consultant model software,the power generation process is simulated.The simulation results show that 3509mw power can be generated every year.In addition,the economic feasibility analysis,assuming a 20-year project cycle,confirms that the net present value of the photovoltaic system is 1903000 yuan.Therefore,it is feasible to install 3 MW photovoltaic power generation system on the tailings dam of Shangdong mine,which can provide an effective choice for the sustainable development of mine wasteland.
