Classical power system stability was mainly focussed on
rotor angle stability but modern power system stability has
more focus on voltage stability.Why?

Majority of blackout/grid failure now a days is due to
voltage instability phenomenon.
This is because Modern power system is very vast and
interconnected to form a grid network.Also generation is
not sufficient to meet the load demand which is incresing
rapidly, due to which load end voltage drops.To maintain
load end voltage and power factor within permissible limits
shunt capacitors are used extesively at almost all load bus
bars(Over compensation),which has detrimental effect on
voltage stability.
At the time of peak load(load increase),the voltage at the
load end decreased so reactive power supplied by shunt
capacitors also reduced.So when we have most need of
reactive power supply,the shunt capacitor prove less
capable.
That's why modern power system satbility problem shifts
towards voltage stability.

how to fit 3 HP crompton gear motor with conveyor with the use of staring delta starter or ordinary starter?
we have require a Motor (1500kW, 6.6kV, 50Hz) which shall operate at 1500rpm during 30min and after it shall run on 500rpm during 15min. The same cycle shall be repetitive during the whole working days. Which method is best and economic to achieve such type of task. VFD, VVFD, Pole changing motor etc.

- two pumps must work with them at the same time but if the first pump start the second pump must delayed for some time to start also , with motor rated power = 90 KW and rated voltage = 380 V and rated power factor = 0.85 lag please draw the power and control circuit for it and determine all circuit components parameters that you use it
