Literature review on Relay coordination using software techniques

-Abstract
In this paper, I presented different techniques for
relay coordination using software techniques. Now days, the
demand of electricity is increasing. So, the network of
electricity from generation to distribution is very large. The
network of state electricity boards typically have 10 to 15 or
more buses, 40 to 50 transmission lines and 80 to 100
overcurrent relays. The exercise of load flow analysis, fault
level calculations and listing the primary backup pairs will be
very tedious. The exercise is very difficult because one has to
consider line contingencies and relay setting are to be decide
based on the worst case. Also several iteration would be required
to calculate TMS of relays so that minimum discrimination
margin as required is found between relay and its backup
relays. This is only by using some computer programming. In
this paper, shows the some algorithm techniques and also
discuss the advantages of latest software ETAP.
