日本基于列车运行能耗模拟器的节能技术效果预测

Forecasting of power saving technology effect based on train operation power simulator in Japan

为在引入新的铁路节能技术之前事先预测其效果,铁道综研开发用于计算直流电气化铁路列车运行耗能的列车运行能耗模拟器。该模拟器可综合考虑外界气温引起的空调负荷变动等因素,具备全面模拟列车在现实环境下按照运行时刻表运行时能耗的能力。利用该模拟器可更精确地研究和预测节能技术引入效果。文章将以储能装置和新型节能车辆引入效果预测作为案例进行说明。

In order to forecast the effects of new railway power-saving technologies before they are introduced,the railway technical research institute has developed a train operation power simulator for calculating train operation power of DC electrified railway.The simulator can take consideration of the air conditioning load change caused by the external temperature and other factors,and has the ability to synthetically simulate the power of the train running according to the running schedule in the real environment.The simulator can be used to study and forecast the effect of power-saving technology more accurately.The study illustrates the powersaving effect forecasting of the effect of energy storage device and the new power-saving vehicles as examples.
