Understanding the energy consumption in different vehicles is becoming more important for train operators. Energy is expensive, and therefore every single percent which can be saved, is important. Today the total estimated consumption for the railway operation is recorded, but it is not possible to accurately apportion the energy consumed by an individual railway operator, or energy used by a particular train on a certain route and by driver!
In Europe the European Commission requires the implementation of Third Party Access (TPA) for all consumers including those in the railway sector, which means: Railway Undertakings (RU) can purchase energy from suppliers of their choice.
Why is energy measuring so important:
Energy meters are needed to make energy savings visible
Energy meters are needed to allocate the profits of these savings correctly to the respective Railway Undertakings
Energy prices are increasing year by year
The liberalization of the Energy Market consequently has brought in new challenges for the railway sector. Changes in regulation, for both energy and railways, has changed the framework and the practice in energy supply, distribution and billing.
Our solution will help train operators in the energy billing process, diagnostics and functionalities related to energy management. It will collect a lot of different data from the train (like voltage, current, calculated current, position etc.), and this data is compliant with the EN 50463 standard (Energy measurement on board trains).
All the recorded data and information is then transferred to an on-ground Data Collection Services (DCS) via the inbuilt 3G/4G/WiFi link. Using a web-interface this data can then be displayed as charts or reports on different devices, like smartphones, laptops or tablets.
Another nice feature and added value of the solution is, that it provides additional protection by continuously monitoring voltage and current inputs, detecting if measured values are outside the pre-set thresholds. These advanced diagnostics information are recorded with the vehicle GPS position, thus identifying issues on the catenary system, and therefore enabling corrective actions to be taken by infrastructure maintainers.
