HXD3型电力机车运行速度与能耗关系试验研究

对于列车节能运行第一、第二论断,以往多采用计算的方法进行论证。HXD3型电力机车是新型大功率交流传动电力机车,其恒力准恒速牵引特性为准确控速带来方便,为组织能耗牵引试验创造了条件。采用能耗牵引试验方法,对这2个论断的正确性进行实际验证,为各型机车能耗试验提供借鉴。

纯电动城市客车驾驶行为与能耗关系的统计分析

对同一设计、同一批次、同一运行线路、不同人员驾驶的4辆城市客车的运行状态和能耗进行统计分析,提出影响车辆能耗特性的驾驶行为特点,并给出优化能耗特性的相关建议。

抽油机井工作制度与能耗关系探讨

油田实际生产中,主要是通过对供液不足抽油机井采取下调参数、间抽等措施节约能耗,随着节能措施不断实施,供液不足井数逐渐减少,节能潜力越来越小,针对此问题,研究如何在正常生产且供液充足的抽油机井上寻找节能潜力,提出通过上调抽油机井参数配合间抽措施,实现能耗下降,降低生产成本,并在现场开展试验应用,选取9口工作制度正常的抽油机潜力井,分别采取换大泵径、调大冲程、调大冲次进行现场试验,全程跟踪测试、验证节能效果,换大泵径、调大冲程后实施间抽节能效果较好,节电率分别达到31.6%、15.5%,具有广泛的推广前景。

国内典型区域建筑能源系统经济和能耗指标比较分析

建筑能源系统的能耗和经济性指标受到气候、建筑类型以及系统形式的影响。从投入产出的视角研究建筑冷热量消耗强度与能源系统形式间的关系,有助于从总体上把握我国典型区域建筑能源系统的形式特征和设计重点。基于典型城市典型建筑的单位面积负荷特征,结合采用不同能源系统形式时的全年运行模拟分析,得到了典型城市典型建筑采用各类常见能源系统时的经济和能耗指标。通过对不同维度建筑能源系统经济和能耗指标的比较分析,厘清建筑能源系统现状,以期指导企业和政府开展建筑能源系统提效工作。

Energy Planning in Small Municipalities Based on Monitoring Results and Demand Side Management

Recent estimates state that the European Union is on course to achieve only half of the 20% energy consumption reduction target by 2020. As the first governmental stakeholders involved in the implementation of energy saving initiatives, municipalities play a strategic role in the energy planning process. This paper focuses on establishment of an energy planning methodology for small municipalities with numbers of inhabitants in range of 1,000-10,000 which often face common problems associated with low efficient district heat supply systems and decreasing energy consumption in buildings. Particular attention is paid to DSM （demand side management） activities. DSM scheme includes legislative and financial flows with small investments from municipality side. Based on increased information and motivation it promotes reduction of energy consumption in all kinds of buildings. Practical experience has shown that application of DSM measures allows achieving 20% energy savings in municipal buildings during the first year.
