涠洲岛微电网耦合海水淡化全生命周期经济性分析

Life Cycle Economic Analysis of Microgrid Coupled Seawater Desalination System in Weizhou Island

针对涠洲岛水电短缺问题,通过对比分析确定了光油气储+反渗透海水淡化的工程组合方案,通过计算推导得出微电网装机容量。对组合系统设备进行选型,利用archelios光伏仿真软件进行辅助设计及计算,最终用成本-效益法计算系统综合效益,得出海水淡化系统效益为4057425元,光伏电站平均年收益为3042971元,投资回收期约6 a,累计收益为34448660元。研究表明,该组合方案具有较高的经济效益,对涠洲岛水电短缺问题的解决具有重要意义。

In view of the shortage of water and electricity in Weizhou Island the engineering combination scheme of solar oil and gas storage+reverse osmosis seawater desalination is determined through comparative analysis and the installed capacity of microgrid is calculated and deduced.The equipment of the combined system is selected and the archelios photovoltaic simulation software is used for auxiliary design and calculation.Finally the cost-benefit method is used to calculate the comprehensive benefit of the system.It is concluded that the benefit of the seawater desalination system is CNY 4057425 the average annual income of the photovoltaic power station is CNY 3042971 the payback period is about six years and the cumulative income is CNY 34448660.The research shows that the combined scheme has high economic benefits and is of great significance to solve the problem of water and electricity shortage in Weizhou Island.
