基于模糊控制的采光控制策略仿真研究

Simulation Research on Fuzzy Control Strategy of Natural Daylight

摘要:

随着人们生活水平的不断提高,我国电力供应日趋紧张,其中照明能耗占据了很大比重；因此,如何在保证室内照度的基础上,充分利用天然光,降低建筑人工照明能耗已经成为照明研究的主要方向；近年来,建筑信息模型(BIM)技术为推动建筑可持续发展的提供了巨大的支持,通过绿色建筑技术量化建筑采光性能,将自然光合理的引入室内,从而减少人工照明所产生的用电能耗；在此基础上,制定了基于模糊控制的百叶窗控制系统,通过单模糊控制与双模糊控制效果的对比,最终输出合适的百叶窗开度,在天然光不足的情况下使用辅助人工照明并调光,最后以南京某办公楼为例,通过ecotect软件进行仿真,分析了一年四季的节能情况,得出节能率；结果证明,控制系统取得了一定的节能效果。

Abstract:

With the constant improvement of people’s living, the pressure of the supply of electric power of our country is becoming more and more serious,among which the lighting energy consumption is inevitable to occupy a large proportion. How to take advantage of natural light, meet requirements of the illumination and reduce the energy consumption of architectural lighting has become a major research direction of lighting construction. In recent year, the technology of Building Information Modeling (BIM) has contributed to building sustainable development,Building lighting performance is quantified through green building technique, and bringing natural light inside reasonably, thus reducing the electricity consumption generated by artificial lighting of buildings. Based on this control strategy, to develop the fuzzy control system based on shutter, contrast the single fuzzy control system with double fuzzy control system, get the most appropriate shutter opening, use auxiliary artificial lighting and dimming when daylight illumination is not enough. Finally, take an office building in Nanjing as an example, simulate and analyse by the software of Ecotect annually, obtain the energy-saving rate. The results show that the control system has achieved a certain energy-saving effect.
