IEC 61850 - Substation Automation Introduction Substation Automation (SA) is a system to enable an electric utility to remotely monitor, control and coordinate the distribution components installed in the substation. High speed microprocessor based Remote Terminals Units (RTUs) or Intelligent Electronic Devices (IEDs) are used for substation automation and protection. Intelligent Electronic Devices, is not “ Improvised Explosive Devices”, Microprocessor-Based Substation Control (MBSC) These IEDs are installed in strategic locations for collection of system data and automatic protection of substation equipment. BCC

IEC 61850 - Substation Automation Data communication between the control centre and IEDs in remote locations and among the IEDs becomes an important issue to realize the substation automation functions. Various protocols are used for tele-control purpose, but none of them fully support the interoperability among IEDs supplied by different vendors in the substation. These protocols are Modbus, Modbus Plus, DNP 3.0, and IEC 60870. Electric Power utilities are facing problem of INTEROPERABILITY among IED supplied by different companies, universal standard to eliminate the problem of interoperability. BCC

IEC 61850 - Substation Automation The standard IEC 61850 „Communication Networks and Systems in Substations“ will provide interoperability between the electronic devices (IEDs) for protection, monitoring, metering, control and automation in substations.

Standard IEC 61850 IEC 61850 - Substation Automation The functions performed by Substation Automation (SA) system are in, general, switch control, data monitoring, protection etc. In IEC-61850, these functions are broken into low-level functions called sub-functions. Each sub-function is performed by the IED installed in the substation. Each IED can perform one or many sub functions. A set of sub-functions is integrated together to realize a substation automation function. These communicate with each other through Local Area Network in the substation.

Mac Address Generic Object Oriented Substation Events, Data Link Layer Protocol, VLAN and Ether-type Event - occurrence of any change of state , an IED will multicast a high speed, Generic Object Oriented Substation Event (GOOSE) report enables high speed trip signals to be issued. Max retransmission timeout parameter defines the final cycle of transmitting GOOSE messages. This can be called GOOSE keep alive cycle and it is common for the IEDs. NO retransmission within this time allows GOOSE Subscribers to assume GOOSE Publisher failure. GOOSE NI signals can be used to trigger relay outputs, to block protection functions, to initiate auto-reclose operations, to block controlled objects. They can also be used in building application logic schemes. For example : Overvoltage and it was configured as GOOSE, the signal is send in Publisher –Subscriber communication mode, where with in 4 ms the GOOSE control is sending in burst repeatedly !, On the occurrence of any change of state!
