4. VOLTAGE PROFILE ESTIMATION DUE TO
INJECTION OF REACTIVE POWER
Change in voltage in terms of the amount of reactive power
injected at the capacitor bus can be given by :
The optimum reactive power injection at the capacitor bus
minimizing the losses-index can be defined as:
6. OPTIMAL OPERATION BY FEEDER
ALGORITHM
End of feeder RTU
2. RTU Downstream of capacitor
3. Capacitor’s RTU
4. RTU Upstream of capacitor
5. Station RTU
For general case
a) Forward phase
b) Backward phase
