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.
通过同时传输交流和直流电源来改善现有交流线路的负载性
为了增加现有交流线路的功率流,需要使用不同的补偿器装置。柔性交流输电系统在提高输电线路的输电能力方面是非常普遍的。由于稳定性的原因,这些补偿方法存在一定的局限性。另一种选择是建造新的交流输电线路,这不仅昂贵,而且耗时。并不是在所有情况下都可行。然而,通过同一条线路传输交流和直流电力可以在不损害网络稳定性的情况下增加潮流。本文研究了当交流线路同时传输交流和直流电源时增加的功率流。为此研究了一种同时传送交流和直流电源的长传输线模型。该模型使用变压器和整流器系统产生并通过线路将这种电力从发电源输送到无限母线。研究比较了传统交流输电线路的潮流和提出的交直流同步输电方案。
