Design of Protection system based on post fault conditions obtained using symmetrical components method.

Modern power systems operate close to their security limits and require highspeed
fault clearing to preserve transient stability, reduce fault damage, minimize
outage duration, and improve power quality. To provide high speed tripping for faults
occurring at any point on a transmission line, there must be some form of accurate
protective relays which operate on the basis of post ....etc

Procedure:-
1. Rewrite the given difference equation to have only the output terms on the LHS and input terms to be on RHS
2. Create a Matrix of Y coefficients, a
3. Create a Matrix of X coefficients, b
4. Generate the input sequence x(n)
5. Find the output of the system for the input sequence x(n)
6. Plot the input and the output
