Power Upgrading of Transmission Line by Combining AC – DC Transmission

  title={Power Upgrading of Transmission Line by Combining AC – DC Transmission},
  author={P. Vijay Kumar Babu and P. Bhaskara Prasad and M. Padma and M. Padma Lalitha},
Long extra high voltage (EHV) ac lines cannot be loaded to their thermal limits in order to keep sufficient margin against transient instability. With the scheme proposed in this project, it is possible to load these lines very close to their thermal limits. The conductors are allowed to carry usual ac along with dc superimposed on it. The added dc power flow does not cause any transient instability. This project gives the feasibility of converting a double circuit ac line into composite ac–dc…

It is difficult to load long extra high voltage (EHV) ac lines to their thermal limits as a sufficient margin is kept against transient instability. With the model proposed in this paper, it will be


Now-a-days, demand for electric power has shown steady but geographically uneven growth.The wheeling of the available energy through existing long ac lines to load centers has a certain upper limit

Power System Stability Enhancement by Simultaneous AC-DC Power Transmission

The feasibility of converting a double circuit ac line into composite ac-dc power transmission line to get the advantages of parallel ac-DC transmission in order to transient stability and dynamic stability and dampen out oscillations is given.

Stability improvement of simultaneous AC-DC power transmission system

This paper presents the concept of simultaneous ac-dc power transmission system with newly designed self adaptive Voltage Dependent control (VDCOL) procedure. Long ac transmission lines cannot be

Loadability improvement of an existing AC line by transmitting simultaneous AC and DC power

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

Stability Analysis of Simultaneous AC-DC Power Transmission System

In high voltage long transmission line the power flow is much lower than its thermal limit due to the constraints related to stability and corona discharge. However, in case of simultaneous AC-DC

Improvement of EHVAC by DC-AC composite Transmission System

Economic concerns have delayed the construction of a new transmission line. The power is often not available at the growing load centers but at remote locations. Often the regulatory policies

The Operation of a Power Transmission Line With Injected Third Harmonic Voltage

An alternative transmission line design method is proposed that reduces the required conductor-to-ground clearance by injecting third harmonic voltage. In this method, third harmonic voltage is



HVDC Conversion of HVAC Lines to Provide Substantial Power Upgrading

The feasibility of conversion of AC lines to DC lines for a substantial power upgrading is analyzed, and it is shown that increases of 3.5 times or more are feasible. The main design objective is to

The unified power flow controller: a new approach to power transmission control

This paper shows that the unified power flow controller (UPFC) is able to control both the transmitted real power and, independently, the reactive power flows at the sending- and the receiving-end of
