多能源耦合系统在严寒地区的应用研究

Application Research of Multi-energy Coupling System in Severe Cold Area

我国严寒地区冬季漫长而寒冷,对采暖要求相对较高。目前,冬季采暖主要还是使用煤等不可再生能源,其对环境污染影响严重。因此,研究适宜于严寒地区的可再生能源解决方案就显得十分必要和迫在眉睫。然而,受严寒地区的冷热负荷特点的限制,单一的可再生能源形式往往无法满足要求,需对多种能源进行耦合来提高系统的安全性和高效性。以长春市某建筑为例,利用DeST软件模拟了全年逐时动态负荷,通过对多种能源耦合方式的研究,得到了既能安全稳定运行又能满足经济性要求的工程应用的指导方案。

The winter in severe cold areas of our country is long and cold,and the requirements for heating are relatively high.At present,heating in winter mainly uses non-renewable energy such as coal,which has a serious impact on environmental pollution.Therefore,it is very necessary and urgent to study renewable energy solutions suitable for severe cold regions.However,limited by the characteristics of cold and heat loads in severe cold areas,a single form of renewable energy is often unable to meet the requirements.It is necessary to couple multiple energy sources to improve the safety and efficiency of the system.Taking a building in Changchun City as an example,this paper uses DeST software to simulate the hourly dynamic load throughout the year.Through the study of multiple energy coupling methods,a guiding plan for engineering applications that can operate safely and stably and meet economic requirements is obtained.
