8.6 NECESSITY FOR REACTIVE POWER COMPENSATION IN A TRANSMISSION LINE

As explanined in Section 8.4, the voltage profile varies with distance along the transmission line. Power system engineers will be happy it they are able to maintain a flat voltage profile throughout the distance of the transmission line, which is the ideal case.

Fig 8.6 Voltage variation over a transmission line.

Power system research engineers have worked for several decades to develop compensation techniques for transmission line, which can maintain the voltage profile close to the ideal case. These compensations are essential because, if the voltage in the system is boosted ...
