Design Control and Protection Panels for different voltage levels and bus arrangements.
Prepare control and protection schematics for generators, transmission lines, transformers, reactors, busbars and other power system equipment.
Configure and work with numerical protection relays from Siemens, Hitachi, GE and other relevant manufacturers.
Prepare FAT, SAT, GTP, TTR, FDS and heat-load calculation documents.
Develop SAS and Process Bus system architectures using Star, RSTP, PRP and Ring topologies.
Work with Ethernet switches, next-generation firewalls, RedBox devices and associated networking components.
Apply knowledge of substation communication protocols, including IEC 61850, IEC 60870-5-101/104, Modbus Serial/TCP-IP, SNTP and PTP.
Understand Master-Slave and Client-Server architectures, IEC 61850 communication and computer networking principles.
Work with SAS platforms and configuration tools such as SICAM SCC, SIMATIC WinCC, RTC A8000, S8000 and MicroSCADA.
Develop suitable Substation Automation System solutions based on customer and project requirements.
Coordinate with customers for drawing approvals and resolution of technical queries.
Initiate material loading documents for factory procurement, fabrication and panel wiring.
Provide engineering support to Sales, Factory, Testing, Project Management and Commissioning teams during project execution.
