Abstract

The railway opening up to competition in Europe is a challenge from the engineering point of view. In energy billing field, this opening asks for a whole new system of energy measurement, as the already installed one is only useful when only one company operates. Even if the European laws impose the installation of energy-meters in new/refurbished rolling-stock since 2015, the chosen configuration doesn’t match the RTE (the French national transmission system operator) defined standards of data reliability. Therefore in this paper, a new procedure for the validation of the data collected by the energy-meter is presented. First the used physical train model is presented, which takes into account the characteristics of the studied train and line. Based on this physical model and different optimization techniques, upper and lower bounds for the total consumption of the train are then defined. These bounds are used to validate the consistency of the data provided by the energy-meters. This data validation technique is tested with real data for a couple of years from a regional passenger train. Finally, a short discussion about the limits of the developed method is presented.

通过物理模型验证铁路电能表数据

从工程的角度来看，欧洲铁路向竞争开放是一个挑战。在能源计费领域，这一开放要求一个全新的能源计量系统，因为已经安装的系统只有在只有一家公司运营时才有用。即使自2015年以来，欧洲法律强制要求在新/翻新的铁路车辆上安装电能表，但所选择的配置也不符合RTE(法国国家输电系统运营商)定义的数据可靠性标准。因此，本文提出了一种验证电能表采集数据的新方法。首先给出了考虑所研究列车和线路特点的列车物理模型。基于该物理模型和不同的优化技术，确定了列车总消耗的上下界。这些界限用于验证电能表提供的数据的一致性。这种数据验证技术是用一列区域客运列车几年来的真实数据进行测试的。最后，对该方法的局限性进行了简要的讨论。
