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 ...
Field validation of gap-type overhead conductor creep
(Elsevier, 2018-09-11)
Gap-type overhead conductor sag-tension calculations based on experimental conductor creep tests are based on stress-strain and metallurgical creep tests. Although for bi-metallic conductors, these tests are carried out ...
Fuel cell-based CHP system modelling using Artificial Neural Networks aimed at developing techno-economic efficiency maximization control systems
(Elsevier, 2017-02-08)
This paper focuses on the modelling of the performance of a Polymer Electrolyte Membrane Fuel Cell
(PEMFC)-based cogeneration system to integrate it in hybrid and/or connected to grid systems and
enable the optimization ...
Model for optimal management of the cooling system of a fuel cell-based combined heat and power system for developing optimization control strategies
(Elsevier, 2017-12-18)
This paper is focused on the development of a model for achieving optimal control of the cooling system of a polymer electrolyte membrane fuel cell (PEMFC)-based cogeneration system. This model is developed to help facilitate ...
Optimized Energy Management Strategy for Wind Plants with Storage in Energy and Reserve Markets
(IOP Publishing, 2019-05-21)
This paper addresses the joint operation of wind plants with energy storage systemsin multiple markets to increase the value of wind energy from an economic and technical point of view. The development of an optimized ...
Analysis of Local Measurement-Based Algorithms for Fault Detection in a Multi-Terminal HVDC Grid
(MDPI, 2019-12-17)
One of the most important challenges of developing multi-terminal (MT) high voltage direct current (HVDC) grids is the system performance under fault conditions. It must be highlighted that the operating time of the ...
