【摘要】：建筑节能是建筑可持续发展的一大研究热点。然而建筑一旦建成,建筑能耗和建筑运行状态密切相关。因此,开展建筑运行节能控制研究对建筑节能降耗具有重要的作用。本文从分析建筑运行能耗的影响因素入手,主要研究内容涉及建筑运行能耗建模与仿真、影响因素分析、节能运行控制策略等方面。主要工作如下:首先,综述了建筑能耗模拟与分析的现状,阐述了研究建筑运行节能控制的目的及意义,指出建筑节能运行控制系统能够在保证室内舒适度的情况下,尽可能的降低室内的建筑能耗,研究建筑运行控制策略是保证建筑节能运行控制的根本,并对本文的主要工作做了简介。其次,基于EnergyPlus建立了建筑能耗仿真模型,研究了不同影响因素对建筑能耗的作用情况。分析主要从两个层面进行,第一是研究单个房间的不同因素对于运行能耗的影响,主要分析了人员、空调、天气、设备数量、设备类型、设备运行时间等;第二是研究整栋建筑层面上的不同因素对运行能耗的影响,主要涉及墙体耦合、阴影、墙体的材料等。再次,设计开发了基于EnergyPlus+MATLAB的建筑能耗联合仿真平台。为解决先进控制算法和建筑能耗模拟的融合问题,通过利用MATLAB的GUI开发了基于EnergyPlus+MATLAB的联合仿真平台,完成了联合仿真平台界面设计和后台调用功能,实现了EnergyPlus与MATLAB的同时调用。该平台所进行的建筑运行节能控制仿真,建筑能耗模拟依靠EnergyPlus实现,控制算法和复杂计算在MATLAB中进行,充分发挥了两大软件的优势,为实现建筑运行的智能控制仿真验证奠定了基础。最后,在所建立的建筑能耗联合仿真平台上,提出了基于模型预测控制的建筑运行节能控制方法。通过建立建筑能耗模型,调用建筑文件以及控制算法文件,配置输入和输出参数,采用模型预测控制算法使室内温度能够维持在相对舒适的区间,实现了建筑运行节能控制。本文研究工作层次递进,从建立建筑能耗模型开始,继而开展了建筑运行能耗影响因素分析,然后为了实现建筑运行节能控制开发搭建了基于EnergyPlus+Matlab的建筑能耗联合仿真平台,最后提出了一种基于模型预测控制的建筑运行智能控制策略。这些研究工作对建筑能耗模拟和节能控制等具有较好地借鉴作用。
[Abstract]:Building energy conservation is one of the research hotspots in the sustainable development of buildings. However, once the building is built, building energy consumption is closely related to the operation state of the building. Therefore, the research of building operation energy saving control plays an important role in building energy saving and consumption reduction. This paper begins with the analysis of the influencing factors of building operation energy consumption. The main research contents are related to the modeling and simulation of building operation energy consumption, the analysis of influence factors, the operation control strategy of energy saving, and so on. The main work is as follows: firstly, the paper summarizes the current situation of building energy consumption simulation and analysis, expounds the purpose and significance of research on building operation energy saving control, and points out that building energy saving operation control system can ensure indoor comfort. As far as possible to reduce indoor building energy consumption, the study of building operation control strategy is the fundamental to ensure the building energy saving operation control, and the main work of this paper has been briefly introduced. Secondly, the simulation model of building energy consumption is established based on Energy Plus, and the effect of different factors on building energy consumption is studied. The analysis is mainly carried out from two aspects. The first is to study the influence of different factors of a single room on the operation energy consumption, mainly analyzes the personnel, air conditioning, weather, equipment quantity, equipment type, equipment running time and so on; The second is to study the influence of different factors on the operation energy consumption of the whole building, including wall coupling, shadow, wall material and so on. Thirdly, the building energy consumption joint simulation platform based on Energy Plus MATLAB is designed and developed. In order to solve the problem of fusion of advanced control algorithm and building energy consumption simulation, a joint simulation platform based on EnergyPlus MATLAB is developed by using MATLAB GUI. The interface design and background call function of the joint simulation platform are completed, and the simultaneous call between EnergyPlus and MATLAB is realized. The simulation of building energy saving control based on this platform is realized by EnergyPlus, and the control algorithm and complex calculation are carried out in MATLAB, which brings into full play the advantages of the two softwares. It lays a foundation for intelligent control simulation verification of building operation. Finally, based on the building energy consumption simulation platform, a building operation energy-saving control method based on model predictive control is proposed. Building energy consumption models, building files and control algorithm files, input and output parameters are configured, and the indoor temperature can be maintained in a relatively comfortable range by using the model predictive control algorithm, thus the building operation energy saving control is realized. This paper starts with building energy consumption model, then analyzes the factors influencing building energy consumption, and then builds a building energy consumption simulation platform based on Energy Plus Matlab for building operation energy saving control development. Finally, a building operation intelligent control strategy based on model predictive control is proposed. These researches can be used for reference for building energy consumption simulation and energy saving control.
