Then a real electric grid, Khorasan electric grid in North-East of Iran, is modeled by dynamic model of generators, AVRs, governors, field current limiting systems and electric loads. The paper is continued by introducing a novel method, called VCI, for real time voltage instability detection. Mentioned method is simulated on Khorasan electric grid and results are analyzed. Keywords: Dynamic modeling, P.M.U., Dynamic load modeling, Transient voltage collapse, Longer term voltage collapse, Real time voltage instability estimation 1386%& "#$ - ! - - www.SID.ir Archive of SID @U- i4 A < !-#a4 C < K A A) O <* <) <J- ) K A ) ? !
