【摘要】：变电站是电能供应链条中非常重要的一个环节，对电力企业来讲，变电站节能具有十分重要的意义。在2008中国国际供电会议上，提出 绿色环保型的电网将成为今后电网建设的主要发展方向‖。目前，国家电网公司提出系统内建设 资源节约型、环境友好型、工业化‖，即 两型一化‖变电站的要求。 变电站建筑能耗具有特殊性，主要是由输配电站区工艺总体要求及电气设备对房间热环境的严格要求所决定的。冷桥节点多，是造成严寒地区变电站冬季采暖能耗较一般民用建筑大的主要原因；电气设备散热量大，，是使变电站夏季产生空调能耗的直接原由。因此，通过节能手段降低严寒地区变电站采暖季能耗、消除夏季空调能耗，是严寒地区变电站节能研究与设计的关键所在。然而，当下变电站建筑节能设计，由于缺少此类建筑的节能设计规范，基本都是从定性的角度提出节能设计策略，缺少科学性，易造成事倍功半的结果。计算机模拟具有直观性、准确性、便捷性等优势，以此为手段对严寒地区变电站建筑进行节能模拟研究，具有节能设计直观化、客观化、精准化等意义。 本文按照问题的提出、问题的解析、问题的解决三个步骤展开。首先，从建筑节能的角度，对严寒地区变电站进行了调研与节能测试，通过所得的数据，分析影响严寒地区变电站能耗的主要影响因素，总结严寒地区变电站的基本能耗特征，确定建筑形体与体形系数、建筑窗墙比、建筑围护结构传热系数、太阳辐射热等因子为严寒地区变电站的主要能耗影响因子，为后文明确研究方向与内容。接着，运用能耗模拟软件DeST-c，分别针对在调研中总结的建筑能耗影响因子进行敏感性模拟研究实验。实验分别得出建筑形体、建筑外围护结构、建筑窗墙比、通风换气次数、太阳辐射强度对建筑能耗的影响关系；在此基础上通过能耗变化规律总结出对建筑能耗起明显作用的各影响因子取值或者影响规律，作为指导典型变电站建筑节能设计调整的参考依据。最后，将抽象的实验数据和结论与依托工程节能设计相结合，实现计算机模拟方法在严寒地区变电站节能设计中的应用。
[Abstract]:Substation is a very important link in power supply chain. At the 2008 China International Power supply Conference, it was proposed that the green and environment-friendly power grid would be the main development direction of power grid construction in the future. At present, the State Grid Company has put forward the requirements of the construction of resource-saving, environment-friendly and industrialized substation in the system. Substation building energy consumption is special, mainly determined by the overall requirements of transmission and distribution station technology and the strict requirements of electrical equipment to the room thermal environment. The large number of cold bridge nodes is the main reason that the substation heating energy consumption in winter is larger than that of the ordinary civil buildings in the cold area, and the large heat loss of electrical equipment is the direct reason for generating air-conditioning energy consumption in the substation in summer. Therefore, reducing the energy consumption of substation heating season and eliminating the energy consumption of air conditioning in summer is the key to the research and design of substation energy conservation in severe cold area. However, the current substation building energy-saving design, because of the lack of such building energy-saving design specifications, basically from a qualitative point of view to put forward energy-saving design strategy, lack of scientific, easy to result in half the result. Computer simulation has the advantages of intuitionism, accuracy, convenience and so on. The research on energy-saving simulation of substation buildings in severe cold area has the significance of visualizing, objectifying and precision of energy-saving design. In this paper, according to the proposed problem, the analysis of the problem, the solution of the problem three steps. First of all, from the point of view of building energy saving, the substation in cold area is investigated and tested. Through the data obtained, the main influencing factors of substation energy consumption in cold area are analyzed, and the basic energy consumption characteristics of substation in cold area are summarized. The factors such as the coefficient of building shape and shape, the ratio of building window to wall, the heat transfer coefficient of building envelope structure and the heat of solar radiation are the main energy consumption influencing factors of substation in severe cold area, which is the research direction and content in the following paper. Then, using the energy consumption simulation software DeST-c, the sensitivity simulation experiments are carried out for the building energy consumption impact factors summarized in the research. The effects of building shape, building envelope structure, window wall ratio, ventilation times and solar radiation intensity on building energy consumption are obtained. On this basis, through the rule of energy consumption change, the paper summarizes the value or law of influence factors that play a significant role in building energy consumption, which is the reference basis for guiding the adjustment of building energy saving design in typical substations. Finally, the abstract experimental data and conclusions are combined with the energy saving design of engineering to realize the application of computer simulation method in substation energy saving design in severe cold area.
