Dynamic Stability Simulation Multimachine Power Generating System

Dynamic stability is one of the parameters to deter-mine the reliability of the system for generating and distributing electrical energy in order to maintain the continuity of electrical energy services. The source of electricity is a necessity that cannot be separated from the life of modern society, the focus of research is on the dynamic stability carried out on power plants that are directly connected to a 500 kV transmission system, changes in the load on the network system result in changes in the generator rotor angle in each generator. The research was carried out by conducting simulations by entering the network parameters, then by using Matlab, the information visualization of the programming results was obtained. Changes in load cause changes in the dynamic stability of the electrical system which causes the rotor angle and system frequency to oscillate at all connected generators.
