摘要
为解决目前城市轨道交通面临的能源消耗总量过大的问题,以北京轨道交通运营线路能耗数据为基础,分析影响城市轨道交通能耗的主要因素,并通过多元线性回归的方法,建立基于运营数据的牵引能耗估算模型,通过测算与实际运营数据的误差为1.6%;同时将不同城市轨道交通的能耗测算方法进行对比,包括列车单位能耗测算法、电力机车耗电量测算法和单位指标测算法,前两者与估算模型的结果误差不超过5%,验证了模型的可行性;通过单位指标测算法的对比分析,反映出估算指标的不合理性。结果表明,相关对比为既有线路能耗的估算和新建线路能耗的预测提供了参考的方法。
The excessive total energy consumption has become a major problem facing urban rail transit. Bases on the energy consumption data of Beijing subway operation line, the main factors that affect the urban rail transit energy consumption were analyzed. An estimation model has been formulated through the multiple linear regression method, and the error is 1.6% compared with the actual operation data. Other calculating methods of the urban rail transit traction energy consumption （including train unit energy consumption, electric locomotive power consumption and unit index） have been compared. The error is not more than 5% between the model results and the results of the previous two, which verified the feasbility of the model. The irrationality of the estimating indicators was also reflected. All of these relevant results can provide some reference for energy consumption estimates of the existing lines and new lines.
