Electric Power Systems (EPS) are exposed to many events that can compromise quality, continuity or reliability of its operation for example: natural disasters, operating failures or device failures. To minimize the impacts to the electrical power system, that some existing data communication network in an electrical substation could cause, the second edition of the IEC 61850 standard defined the use of active redundancy means for that network, for example, the Parallel Redundancy Protocol (PRP) defined by the IEC 62439 standard, which the main objective is increasing the reliability and continuity of the data communication network. For applications of the IEC 61850 standard to the protection systems, the latency of Generic Object Oriented Substation Events (GOOSE) messages is a pressing concern, because it may have deleterious influence on the time performance of those systems. In this research, the influence of the PRP on the behavior of the GOOSE messages during the occurrence of a disturbance in the communication network will be evaluated. Therefore, a laboratory apparatus was developed making possible the evaluation of a PRP network under different traffic conditions (basal and concurrent). The results of the PRP network were compared with a redundancy method that uses a hot-standby failover mechanism and show that the PRP doesn’t degrade the behavior in the GOOSE messages timming while to the hot-standby failover was observed a pronounced transient component in those messages. |
