【摘要】：目前,世界各国都存在着能源紧缺和环境污染的问题,能源危机的爆发迫使各国制定了相应的措施。在我国,建筑能耗占据了很大一部分的比重,所以建筑节能问题刻不容缓,是迫切需要解决的问题。而电气节能是建筑节能的重要组成部分,因此本文就建筑节能问题进行了详细的阐述。本文首先以建筑电气的变压器、电力电缆、照明灯具、电动机为研究对象,做出了理论分析,并在此基础上总结了其有效的节能方式。通过分析变压器的主要技术参数、功率损耗的基础上,制定了变压器的节能方案;针对照明的种类、方式、灯具布置及其节能途径进行详尽的阐述;分析了选择线路要素及减少其损耗的方法;总结了电动机的选择及特性,进一步体现了它在节能中的应用。同时介绍了瞬时无功功率的检测方法。运用Matlab/Simulink工具对谐波电流检测方法—无源滤波器、p-q检测方法和ip-iq检测三种方法来建模、仿真。其次,随着世界各国对新能源的重视,结合实际生活,本文重点介绍了光伏发电系统,利用光伏设计软件PVSyst,提出设计方案,查找资料,依据现实状况对商场地下超市的照明光伏供电系统进行了设计和仿真,得到发电量的仿真结果。最后本文以松原市儿童医院综合楼为依托,将上述节能理论方案及光伏发电技术应用到工程实例当中,将优化前后的能耗进行对比,不仅满足了设计上的要求,同时也减少了能源的消耗。
[Abstract]:At present, energy shortage and environmental pollution exist in all countries in the world. The outbreak of energy crisis forces countries to formulate corresponding measures. In China, building energy consumption accounts for a large part of the proportion. Therefore, the problem of building energy saving is urgent to be solved, and electrical energy saving is an important part of building energy conservation. Therefore, this paper expounds the problem of building energy saving in detail. Firstly, this paper takes the transformer, power cable, lighting lamp and motor of building electricity as the research object and makes a theoretical analysis. Based on the analysis of the main technical parameters of the transformer and the power loss, the energy saving scheme of the transformer is established. According to the type, mode, arrangement of lamps and lanterns and energy saving way of lighting, it is elaborated in detail; The selection of line elements and the methods to reduce the loss are analyzed. The selection and characteristics of the motor are summarized. At the same time, the detection method of instantaneous reactive power is introduced. The harmonic current detection method-passive filter using Matlab/Simulink tool is also introduced. The p-q detection method and ip-iq detection method are used to model and simulate. Secondly, with the attention of countries in the world to new energy, combined with the actual life, this paper focuses on the introduction of photovoltaic power generation system. Based on the PV design software PVSyst, the design scheme is put forward, the data is searched, and the lighting photovoltaic power supply system of the underground supermarket is designed and simulated according to the actual situation. Finally, based on the comprehensive building of Songyuan Children's Hospital, the energy saving theory scheme and photovoltaic power generation technology are applied to the engineering example, and the energy consumption before and after optimization is compared. Not only meet the design requirements, but also reduce energy consumption.
