Why do we need Electromagnetic Transient studies? The presentationwill focuson the requirementof ElectromagneticTransient(EMT) studiesin modernpower systems.The purposeof the presentationis to answer the questions“whatareEMT studies?”and“why dowe needthem?” Withthe highpenetrationof Inverter BasedResources(IBR) in modernpower systems,the dynamicsand the way we studythemhave changedsignificantly.EMT studies playan importantroleinthe way we studyapower systemnowadays.Inotherwords, EMT studiescapturemanyphenomenawhere traditionaltransientstability(RMS-based) studies cannot due to inherent platform differences. The presentation also introduces fundamental concepts of EMT simulation and circuit solution methods. In addition, EMT vs RMS type simulation results, some newer applicationsforEMT studiesanda fewexample resultsof EMT simulationswill bepresented. Lastbut not least,the mainquestionsto a new EMT studyengineer/institutewill be answered,i.e. “How do we get started?Whatwould be theinitialstudies?Wheredo we get themodels?Andwhatdowe lookforinresults?
