Abstract

A switch-yard is a part of an electrical generation, transmission and distribution system.  In a switch yard there are unit feeders and out-going feeders. The paper deals with 400KV switchyard automation. One of the out-going feeders is considered for automation. The elements of the O/G feeders are Bus Isolators, Circuit Breaker, Line Isolator, Earth switches and elaborate Protective Relay circuits. Separate relay panels are available to take care of protection of each and every element in the yard. It is responsible to isolate faulty section immediately in very minimum time, under abnormal situations. Hence at most importance is given for control and protection scheme design. It is a reliable technology working in real-time .By introducing PLC into the switch-yard automation, each and every input/outputs (I/O) will be terminated with remote terminal units.
