BS PD CLC/TR 50646:2015

BS PD CLC/TR 50646:2015 provides recommendations for DC reversible substations. These recommendations applyto systems and components that facilitate the flow of energy to and from the upstream AC grid including theirrelated interfaces.These recommendations provide the necessary functions for the recovery of braking energy. It is intended to beused in fixed electrical installations with nominal voltage not exceeding 3 000 V DC which supply electricalpower to vehicles used in public guided transport systems, i.e. railway vehicles, tramway vehicles, undergroundvehicles and trolley-busesIt is intended to provide an overview of state-of-the-art applications, define the minimum recommendations thatare presently available, and provide functional recommendations to be applied to these substations.This document focuses mainly on the substation converters and the traction transformers. Other devices suchas switchgear - if they are the same as in classic substations - are not addressed here. Moreover thisspecification addresses performance, constraints, validation and acceptance criteria for the implementation ofreversible substations.This document provides the minimum recommendations to be fulfilled. However, due to the different possiblesolutions and different types of existing technologies, this document does not provide technical specifications ofthe basic components that facilitate the functionalities described.Cross References:EN 50160EN 50163EN 50327EN 50328:2003EN 50329 EN 50388IEC 60050EN 50119EN 50121-1EN 50121-2EN 50121-5EN 50122-1EN 50122-2EN 50123-1EN 50123-2EN 50124-1EN 50124-2EN 50125-2EN 50126CLC/TS 50562CLC/TS 50591EN 60146-1-1IEC 60146-1-1EN 60146-1-3IEC 60146-1-3EN 61000-2-4IEC 61000-2-4EN 61000-2-12IEC 61000-2-12EN 61000-4IEC 61000-4EN 61643-11IEC 61643-11 EN 61800-5-1IEC 61800-5-1EN 62305IEC 62305IEC/TR 60146-1-2IEC/TR 61000-3-6COMMISSION REGULATION (EU) No 1301/2014
