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 …
