The time delays are due to the use of measurement devices and communication links for data transfer. The maximum amount of time delay known as delay margin that the system can tolerate without becoming unstable is determined using Matlab/Simulink. It is found that the addition of a PSS to the excitation system increases the delay margin and improves the system damping significantly.eninfo:eu-repo/semantics/closedAccessConference Object4314352-s2.0-68949213728N/AWOS:000263146900084N/A
