Optimal Allocation of Capacitors for Loss Reduction in Distribution ...
The system losses after capacitor allocation have been noted, and it has been discovered that the system losses reduce as the number of capacitor installation locations increases. The decrease in actual power losses slows as the number of positions increases. The cost of installing capacitors rises with a greater number of capacitors.
Series Compensation of Transmission Systems: A Literature Survey
The compensation degree of the transmission line is controlled in a step-wise way by increasing the number of the inserted capacitors. A capacitor is inserted by using the thyristor valves, by activating (or not) the gating signals. Conversely, a capacitor is bypassed by conducting fully the thyristor valves .
