Abstract Experimental tests of a small polygeneration plant unit based on hybrid renewable energy and desalination have been used to validate a novel model simulation of this plant. It provides electricity by coupling photovoltaic/thermal collectors and a micro-wind turbine, fresh water by means of hybrid desalination (membrane distillation, and reverse osmosis), and sanitary hot water coming from the photovoltaic/thermal collectors and an evacuated tubes collector. Plant was designed to operate in off-grid conditions and conventional energy storage systems were used (lead acid batteries and hot water tank). Simulation model was performed in TRNSYS environment and it was fully validated by comparing several key plant measurements. The analysis was focused on five typical days of summer, fall and winter. Some differences found in experimental and simulated values were analysed. To reduce those gaps, some modifications have been suggested to the model or the pilot unit respectively. As a result, a validated model in TRNSYS of the plant was obtained. This model can be used for the further scale up of new projects to cover any other scheduled demands of power and water in isolated areas, whenever is based on the combination of the abovementioned technologies.

用混合可再生能源和脱盐技术验证国内三联产计划模拟模型的实验测试

摘要 基于混合可再生能源和海水淡化的小型多联产电厂装置的实验测试已用于验证该电厂的新型模型模拟。它通过耦合光伏/集热器和微型风力涡轮机提供电力，通过混合淡化（膜蒸馏和反渗透）的淡水，以及来自光伏/集热器和真空管集热器的卫生热水。工厂设计为在离网条件下运行，并使用传统的储能系统（铅酸电池和热水箱）。仿真模型是在 TRNSYS 环境中执行的，并通过比较几个关键的工厂测量结果得到了充分验证。分析集中在夏季、秋季和冬季的五个典型日子。分析了在实验值和模拟值中发现的一些差异。为了减少这些差距，已经分别建议对模型或试点单位进行一些修改。结果，在工厂的 TRNSYS 中获得了经过验证的模型。该模型可用于进一步扩大新项目的规模，以涵盖孤立地区的任何其他预定的电力和水需求，只要基于上述技术的组合。
