Transmission Line Loadability Increase through Series compensation

2018 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM), 2018
This paper deals with the loadability of seriescompensated lines. Aim of the paper is to provide loadability curves calculated considering various technical limits, namely the thermal limit, the voltage drop limit, the Joule losses limit, and the steady-state stability limit.

Letter to the Editor: A New Line Loadability Index for Radial Distribution Systems

Electric Power Components and Systems, 2008
Abstract Based on the non-negative property of the discriminant of a voltage double-quadratic equation, a new line loadability index, Ls, for radial distribution systems is proposed. The Ls index can be used to assess voltage instability and the line loading margin. This article also mathematically proves the uselessness of an existing line loadability

Extended transmission line loadability curve by including voltage stability constrains

2008 IEEE Canada Electric Power Conference, 2008
St. Clair curve provides a simple means for estimating power transfer capabilities of transmission lines. It concerns three limiting factors: thermal limit, voltage quality (or drop) limit, and angular stability limit. This paper illustrates the influence of voltage stability limit and presents an extended loadability curve.

Line loadability analysis including var supply capability and load voltage characteristics

2008 Third International Conference on Electric Utility Deregulation and Restructuring and Power Technologies, 2008
If the reactive power (var) supply capability is not constrained; the transmission line loadability may be limited by the angle or thermal static stability. Once the reactive power supply is limited or not great enough to support the operation, the transmission line loadability will be limited by voltage.

Optimum compensation to improve line loadability

Electric Power Systems Research, 1990
Abstract This paper presents ‘optimum compensation requirement’ (OCR) curves to select the optimum series and shunt compensation to be employed for different loading conditions of EHV AC transmission systems. The OCR curves enable improvements to be made to the system loadability from the points of view of compensation effectiveness, total ...

Online transmission line loadability assessment using synchrophasor measurements

2013 North American Power Symposium (NAPS), 2013
This paper proposes a measurement-based method to assess transmission line loadability, particularly when determined by stability constraints. A power system two-area equivalent model provides the basis for the proposed line loadability assessment method, with the angle across this equivalent model defining a metric of the closeness to the system ...
