The paper is concerned with the Power System Protection
schemes and the resulting design requirement that enhances stability
as well as control with the implementation of TCP/IP. It discusses the
architecture that upgrades the existing scheme by controlling all the
control signals traffic between generating units, transmission system,
connected loads and protection devices that are sensitive to control
signals using TCP/IP and results are compared using Graphics User
Interface (GUI) in MATLAB/Simulink. Protection system describes
latest breakers circuit using indirect tripping command from
generating units that protects load side through load breakers that
receives action signal from local controllers that have a direct
communication linkage with main server having strong data base,
directly monitors everything through TCP/IP platform using GUI.
