Aspects to take into account in the application of mechanical calculation to high temperature low sag conductors
(The Institution of Engineering and Technology, 2010-05)
Reconductoring with high temperature low sag (HTLS) conductors is an alternative to the traditional uprating methods. The obtained rating increase depends on the mechanical and thermal behaviour of the conductor. In this ...
Review of dynamic line rating systems for wind power integration
(Elsevier, 2016-01)
When a wind power system is connected to a network point there is a limit of power generation based on the characteristics of the network and the loads connected to it. Traditionally, transmission line limits are estimated ...
Tension and Ampacity Monitoring System for Overhead Lines
(IEEE, 2013-01-01)
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 ...
A method for the sag-tension calculation in electrical overhead lines
(Praise Worthy Prize, 2011-06)
The sag and tension values of overhead conductors are influenced by the creep developed during the line lifetime. This paper presents a method for the sag-tension calculation of overhead conductors that is characterised ...
Influence of the conductor temperature error on the overhead line ampacity monitoring systems
(The Institution of Engineering and Technology, 2011-04)
Many real time overhead line ampacity monitoring systems are based on the calculation of the wind speed. The wind speed is obtained from the conductor temperature. The conductor temperature can be measured directly or it ...
Adaptive Static Line Rating for Systems with HTLS Conductors
(IEEE, 2018)
Operation and planning of a power system are constrained by the rating of power lines. Usually, the static line rating is used for system operation and planning. The static line rating defined for an electric grid uses the ...
Forecast Ratio and Security Analysis of Rating Forecasting Methods in an Overhead Line
(The Institution of Engineering and Technology, 2017-01-26)
The actual line rating in overhead lines varies with weather conditions. When a utility defines a rating value for the operation of the line, it takes into account both the security and the forecast ratio. The defined ...
