  • Tension and ampacity monitoring system for overhead lines
    2013
    Co-Authors: I Albizu, Eduardo Fernandez, P Eguia, E Torres, A J Mazon
    Abstract:

    Real-time monitoring allows the determination of the line state and the calculation of the actual rating value. The real-time monitoring systems measure sag, Conductor Tension, Conductor temperature, or weather-related magnitudes. In this paper, a new ampacity monitoring system for overhead lines, based on the Conductor Tension, the ambient temperature, the solar radiation, and the current intensity is presented. The measurements are transmitted via general-packet radio service to a control center where a software program calculates the ampacity value. The system takes the creep deformation experienced by the Conductors during their lifetime into account and calibrates the Tension-temperature reference and the maximum-allowable temperature in order to obtain the ampacity. The system includes hardware implementation and remote-control software.

  • hardware and software architecture for overhead line rating monitoring
    2011
    Co-Authors: I Albizu, A J Mazon, Eduardo Fernandez, J Bengoechea, E Torres
    Abstract:

    Real time monitoring in both electrical transmission and distribution lines is an interesting option for knowing the electrical load level of these lines. The information about the load level allows alleviating the overloaded lines if the power can be transferred to other lines. In this paper, a new ampacity monitoring system for overhead lines, based on the Conductor Tension, the ambient temperature, the solar radiation and the current intensity, is presented. The measurements are transmitted via GPRS to a control center where a software program calculates the ampacity value. The system takes into account the creep deformation experienced by the Conductors during their lifetime and calibrates the Tension-temperature reference and the maximum allowable temperature in order to obtain the ampacity.

  • mechanical state estimation of overhead transmission lines using tilt sensors
    2010
    Co-Authors: Sunita Malhara, Vijay Vittal
    Abstract:

    The electrical transmission infrastructure worldwide has witnessed severe environmental hazards, accidents and in countries like Columbia and India malicious attacks leading to the sabotage of transmission towers. These events underscore the need to develop new techniques to ensure safe and reliable operation of the transmission infrastructure. This paper deals with an online monitoring technique based on mechanical state estimation of overhead transmission lines subjected to tower tilt. The proposed approach provides a quick assessment of the grid condition at the initial stages of an extreme mechanical event. A computational algorithm based on least squares state estimation is applied to transmission line sag-Tension equations developed through a geometric transformation to determine Conductor sag levels. The measurements of tower tilt, Conductor Tension, core temperature, inclination angle of Conductor with the horizontal and other transmission line parameters are utilized for the purpose of state estimation. Appropriate warning alarms generated in the case of considerable changes in the sag levels or violation of limits enable operators to take designated actions during the initial stages of the physical disruption.
