Overview
This standard specifies the requirements and test methods for a stationary energy storage system to be introduced as a trackside installation and used in a power supply network of a DC electrified railway. This system can take electrical energy from the DC power supply network, store the energy, and supply the energy back to the DC power supply network when necessary. Such a system may be installed to achieve one or more of the following objectives: - absorption of regenerative energy: - effective use of regenerative energy (saving energy); - reduction of rolling stock maintenance (reduction of brake shoe/pad wear, etcetera); - avoidance of adverse effects of heat generated during braking (e.g. in tunnels, etcetera); - power compensation: - compensation of line voltage; - reduction of peak power; - reduction in the requirement of the rectifier ratings. The responsible committee is DKE/UK 351.2 "Ortsfeste Anlagen" ("Fixed installations") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
