Preventing of transient voltage instability due to induction motor loads by static condenser

A new digital simulation method for the study of transient voltage stability in electric power systems is presented in this paper. With the aid of this simulation method, transient voltage instability prevention due to the presence of large induction motor loads at the terminals of long transmission lines by the static condenser (statcon), is analysed. The simulation results are compared with those of the thyristor controlled reactor/fixed capacitor static VAr compensator (SVC). It is demonstrated from the simulation results that the statcon is practical in preventing transient voltage instability.<
