Abstract

The present disclosure relates to a system (100) for controlling communication between a first protection system (PS_A) at a first substation (10_A) of an electrical power network (EPN) and a second protection system (PS_B) at a second substation (10_B) of the electrical power network (EPN), wherein the first substation (10_A) and the second substation (10s) are each electrically connected to a power line (PL), wherein a first protection relay (R_A) of the first protection system (PS_A) and a second protection relay (R_B) of the second protection system (PS_B) provide differential protection, the system (100) comprising: a communication network (1000), the system (100) is configured to: communicate critical data and non-critical data between the first protection system and the second protection system via said plurality of communication paths, wherein said critical data comprises first source data (SD_A) representing a first power line measurement of the power line (PL) at the first substation (10_A), and/or second source data (SD_B) representing a second power line measurement of the power line (PL) at the second substation (10_B), wherein the system (100) further comprises: at least one traffic shaper configured to control at least one network parameter associated with at least one node of said communication network to provide from said plurality of communication paths at least one traffic-shaped communication path in which communication of critical data is prioritized over non-critical data. An electrical power network (EPN) comprising the system and a method of controlling differential protection communication are also disclosed.
