Flexible,rapid and reliable integrated protection and control system is required for the smart distribution substation due to the large penetrations of distributed generations and the higher level requirements of customer power supply.The good solution to enhance the performance of the relay and the controller is to use the abundance data from multiple bays in process bus,but the challenge is how to guarantee the real-time accurate data communications among IEDs.In response to this question,the data exchanges on process bus among IEDs were modelled and simulated based on OPNET software;the tests on the developed integrated protection platform were presented to check the simulation results.Then the reason of time delay was analyzed,and the feasible maximum of data sharing bays was achieved,the following improvement measures were also proposed in this paper.The research provides the communication base for the following developments of integrated protection and control system in smart substations.
