load flow analysis - he voltage of generators, power requirement or load centers and line impedances are input and the resulting voltages at
the various buses ("terminals) are found out. Of course the voltages should be within tolerances. Note that in this case we cannt assume loac
voltage to be the nominal voltage as In the case of domestic installation, but has to be calculated by solvine non-linear multivariable equations
2) short circuit studies - Various short circuits are simulated and resulting fault currents are found out to select appropriate
switchgear for the power system. 3) Stability studies - As generators work in synchronism sudden load changes or faults coulc
cause of them to go out of step, which has bus to has to be dealt with.
