    Synchrounous Machine Dynamic Model

    Dear Friends I faced a problem in Synchrounous machine dynamic model. I cant understand stator mutual inductance as follow: Lab=-Ms-Lm cos(2*teta+pi/3) , Lbc=-Ms-Lm cos(2*teta-pi) , Lac=-Ms-Lm cos(2*teta+5pi/3). Why does phase shift as follow: pi/3 , pi , 5pi/3 ?

    Determining P line model parameters

    Dear friends! I am implementing a distribution test system in MATLAB/SIMULINK. The conductor catalogue and tower characteristics are available. I would like model line by transmission line P-model. At first, capacitance, inductance and resistence matrix (that is 3*3 dimensions) hase been...

    ATP/EMTP TACS

    You are right: "The TACS coupling is connected to the node where the variables are available.", but for exporting machine speed, which node of UM3? And what is name that TACS saved for machine speed variable?

    ATP/EMTP TACS

    Dear Friends; I am facing some problems in simulating speed control of Drives, since I do not have access to motor speed parameter; I need to get it with TACS in ATP-EMTP. In ATP, the "coupling to circuit" TACS element used for exporting a parameters, which node do I connect this element. And...
