Substation Automation System
Substations are integral part of any plant which consume or export power. This substation needs to be automated so that the parameters are monitored continuously so that the plant’s consumption adheres to the designed boundaries. In order to achieve that the automation system employs several IEDs such as RTUs, reclosers, PLC , V meters, metering at several stages switching, volt / VAR , wave form monitoring, event data, management etc. It is also essential to follow the required IEC standards.
SIAS has executed several Substation automation projects for
