Up-Gradation of Power System Protection Scheme through TCP/IP Using GUI in MATLAB/Simulink

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.
