6. Power flows and voltage stabilities in power systems
Appendix
Some examples of voltage stability calculations
Case 1: Only constant impedance load circuits are connected.
Voltage is kept.
Voltage phase angle difference is aparent.
ATP Data Source
Case 2: 60% of the load is induction motor.
Voltage is collapsed.
ATP Data Source
Case 3: Like case 2 but shunt capacitor is added.
Voltage is kept.
ATP Data Source
Case 4: Like case 2 but with series capacitor
50% of line reactance is compensated.
Voltage is kept.
