“…Bu dalgaların hattın bir noktasından diğer bir noktasına ulaşması dalga hızına bağlı olup, hattın dalga hızını hat parametreleri belirlemektedir. İletim hattındaki bir x mesafesindeki akım veya gerilim dalgasının hat üzerindeki yayılma süresi τ olup denklem (1) ile hesaplanabilir [11,12].…”

“…Yayılım süresi ile arıza noktası arasındaki ilişkiden yararlanarak iletim hattındaki arıza noktasının kaynağa olan uzaklığı belirlenmektedir. Bu teknik kullanılarak yapılan çalışmada arıza sonrası oluşan geçici rejim harmonik frekansların arıza noktası ile orantılı olduğu belirlenmiş ve bu frekans değerleri kullanılarak arıza mesafesinin hesaplanabildiği gösterilmiştir [11,12]. Bu yöntemde arıza noktasının faz açısı, hat parametreleri ve arıza noktası empedansından etkilenmediği de belirlenmiş ve arıza tespiti için hattın tek tarafından alınacak 1 periyod hatta daha az sinyal ölçümünün yeterli olması literatürdeki pek çok yönteme göre önemli üstünlük sağlamaktadır.…”

Özetçe-Günümüzde enerji sürekliliği ve kalitesinin önemi artmıştır. Arıza nedeniyle meydana gelen enerji kesintileri özellikle sanayi tesislerinde üretimin aksamasına, iş gücü ve kaynak kaybına yol açabilmektedir. Güç sistemlerindeki enerji kesintilerin önemli nedenlerinden biri iletim hatlarında meydana gelen kısa devre arızalardır. Bu arızalara kısa sürede müdahale etmenin en önemli şartı ise arıza noktasının hızlı ve doğru bir şekilde tahmin edilmesidir. Bu çalışmada seri kompanzasyon uygulanmış uzun enerji iletim hatlarında arıza sonrası meydana gelen geçici rejim frekans spektrumundan faydalanarak arıza uzaklığı bulunmuştur. Yöntemin seri kompanzasyon uygulanmış hatlar için uygun olduğu belirlenmiştir. Anahtar Kelimeler -tek faz kısa devre arızaları; arıza uzaklığının belirlenmesi; geçici rejimler; hızlı fourier dönüşümü.Abstract-Nowadays sustainability and quality of energy have gained more importance. Power outages due to failures particularly cause interruption of production at industrial facilities may lead to loss of manpower and resources. One of the major causes of power outages in the power system is the short-circuit faults occurring in transmission lines. The most important requirement to clear the fault in a short time is to estimate the fault location quickly and accurately. In this study, fault location is determined in series compensated power transmission lines utilizing transient frequency spectrum. It has been shown that the method is suitable for series compensated lines. Keywords -single phase short circuit faults; determination of fault distance; transient regimes; fast fourier transform.

“…In electrical engineering, NDT has been used for detection, characterisation, localisation and sizing of discontinuities [2]. A number of NDT techniques have been introduced to detect and locate flaws in power transmission lines using various methods such as visual inspection, infrared camera inspection, ultrasonic inspection, neutron radiography, magnetic method, electromagnetic induction (eddy current), and time domain reflectometry It is worth mentioning that the majority of these methods need mobilisation by foot, ground vehicle, or air vehicle, and require labour presence in the locality of the line.…”

Abstract-Aluminum Conductor Steel Reinforced (ACSR) cables, as part of transmission lines, are used in severe environments in coastal areas and industrial zones for many years. These cables are affected by galvanic corrosion in the interface between the aluminum and steel strands. This paper investigates the existing methods of corrosion detection used in ACSR cables of overhead transmission lines, and estimates the location of corrosion through simulation in a computer program. The paper also analyses two promising methods of corrosion detection, namely "electromagnetic induction" and "time domain reflectometry (TDR)", and explains in detail their principle of operation and efficiency. The paper then thoroughly investigates the time domain reflectometry techniques by implementing it in a computer program, and the simulation results are discussed.

This study proposes an intelligent traveling-wave (TW)-based protection algorithm for parallel transmission lines. In the proposed algorithm, Karenbauer's phase to modal transform is applied on three phase current signals. Teager energy operator is then applied on the modal components to extract TWs. First extracted TW of each modal component along with well-designed fuzzy systems are used for internal fault identification and fault type classification. In order to find the fault location, the time difference between the first and the second TWs and the TW propagation speed are utilised. Test signals are generated in PSCAD/EMTDC software and the algorithm is implemented in MATLAB. Results show that the proposed algorithm is an ultra-high-speed algorithm for the reliable protection of parallel transmission lines.
