SAS commissioning
We know that substations are the building blocks of the power grid. NISSI has been automating those substations with the highest interoperability, and providing grid operators and owners with the highest efficiency and increased productivity. Without sufficient protection, those substations can quickly come tumbling down. NISSI has been preventing that happening successfully with protective relays and breakers connected over bulletproof telecommunications.
In this Modern world, the automation of the substation is digitalized so that we can increase controllability, facilitate the integration of intermittent renewables and improve safety by replacing copper cabling with fiber optics. NISSI Grid Automation enables the digitalization of the grid so that our customers can improve reliability and ensure a safe and clean energy supply to their consumers.
Our SAS commissioning includes services such as the design of system architecture, hardware & software recommendations, supply of hardware & software requirements, database creation, ethernet switch configuration, commissioning of BCU, BCPU, and PMU, web hosting and FTP configuration, controllers communication through OPC protocol construction, HMI & Gateway configuration and SAT- Point to Point Testing.
Relay Testing – Testing the relay is managed in different ways, but the goal is to prove the relay settings, relay logic, and relay functions are all working to “asset” settings, Element testing can be accomplished via manual or automatic testing and Strive to test relay logic with real dynamic testing
Dynamic Logic Testing – Don’t just pulse/jumper contacts, create relay reaction by injecting values into the relay, Use logic diagrams and yellow line them as they are tested is a great way to understand the relay logic and Better yet, draw your own logic diagrams and test them, Make breaker reclose or not reclose, Block close by injecting false sync values Block transfer tripping with c/o switch, and Roll LOR with Breaker Failure or DTT RX
