DESIGN AND OPTIMAL SOLUTION ON UNIFIED SUBSTATION AUTOMATION SYSTEM IMPLEMENTATION

The IEC61850 based substation automation system (SAS) solution are being implemented by many providers to power industry which is open challenge to re-fine communication network, IED interoperability and HMI functionality to derive the improvement in SA protection ,control and monitoring. The available multi-vendor SA system could not get uniform SAS functionality. Therefore, this paper will review the SAS engineering design, SA architecture, communication network & its interconnection with PRP and HSR protocol. The proposed SA architecture including HMI uniform functionality based on optimal solution have been presented in this paper in line with described design process methodology .the proposed scheme will helpful for diagnosis fault during maintenance, ease for operator to manipulate uniform SA system ,got better performance, reduce cost of system and become reliable.
