Abstract
To increase the power flow through an existing AC line, different compensator devices are used. Flexible alternating current transmission system (FACTS) are very common for the enhancement of power transmission capability of the line. Due to stability reasons, these compensation methods have limitations. Another alternative is to construct new AC transmission lines, which is not only expensive, but also time consuming. And it is not viable for every situation. However, transmitting both AC-DC power through the same line can increase the power flow without impairing the stability of the network. This paper investigates the increased power flow through an AC line when it is used to transmit both AC and DC power simultaneously. A model of a long transmission line carrying simultaneously both AC and DC power is studied for this purpose. The model uses a system of transformer and rectifier to produce and carry such power from a generating source to an infinite bus through the line. The study compares the power flow of the traditional AC line and the proposed simultaneous AC-DC power transmission.
