We define the reactive power to be positive when it is absorbed (as in a lagging power factor circuit).. a. Pure capacitance element – For a pure capacitance element, P=0 and I leads V by 90° so that complex power is:. S = jQ = (V ∠0°) (I ∠90°) S = V×I ∠−90° S = −jV×I. Thus the capacitance element generates reactive power.

Series compensation is the method of improving the system voltage by connecting a capacitor in series with the transmission line. In other words, in series compensation, reactive power is inserted in series with the transmission line for improving the impedance of the system. Thus, it improves the power transfer capability of the line. Series …
Reactive Power Role and Its Controllability in AC Power Transmission …
The above expression shows that an ideal line (with zero resistance) loaded at its surge impedance loading does not produce or consume reactive power, so it will have the same voltage at both ends. When a line is loaded above its SIL, it acts like a shunt reactor which are absorbing the reactive power from the system, and when a line is …
