“…The shunt reactors are generally parallel connected at both sides of the long overhead transmission lines or pipe-type cables [1], [2]. They are used to consume the capacitive reactive power produced by line/cable capacitance, which helps to control/stabilize the system voltage.…”

In this paper, the analysis and simulation of shunt reactor turn-to-turn faults, as well as the algorithms for their detection, are presented. A simple equivalent circuit of a shunt reactor applicable for a small number of short-circuited turns was developed and applied to simulate such faults. It is shown why the commonly applied differential relays are not able to detect turn-to-turn faults. Then three new algorithms are introduced and their performance is analyzed for simulated internal faults. The proposed methods are based on zero-sequence reactance, negative-sequence reactance, and phase impedance. The sensitivity and security of the presented methods are discussed. The proposed algorithms' performance has been tested with the signals generated with the use of the MATLAB/Simulink program. The results confirm that the proposed algorithm can effectively improve the detection of turn-to-turn faults. The paper ends with recommendations for the setting of the proposed protection schemes.

Bu çalışmada demir çekirdekli şönt reaktörlerde hava aralığı kullanımının reaktör hacmi, boyutları ve demir kayıpları üzerine etkileri araştırılmıştır. Ayrıca hava aralığı sayısının reaktör demir kayıplarına etkisi sonlu elemanlar yöntemi kullanılarak analiz edilmiştir. Tek-fazlı, demir çekirdekli bir şönt reaktör için önce her bacakta sadece bir adet hava aralığı kullanılarak, sonrasında ise farklı sayıda hava aralığı reaktör bacakları boyunca eşit sayıda dağıtılarak Maxwell programı yardımıyla reaktör çekirdeği boyunca manyetik alan yoğunluğu dağılımları elde edilmiştir. İkinci bir analiz sonucunda ise yine aynı hava aralığı sayıları için şönt reaktörün toplam demir kayıpları hesaplanmıştır. Farklı sayıda hava aralıkları için saçaklanma akısı nedeniyle oluşan ekstra demir kayıplarını minimize edecek optimum hava aralığı sayısı tanımlanmıştır.Anahtar Kelimeler -Demir kaybı, hava aralığı, saçaklanma akısı, sonlu elemanlar yöntemi, şönt reaktör.

Modeling of accurate nonlinear shunt reactor is basis of harmonic analysis of 1000kV AC transmission system. Based on the electromagnetic relations of single-phase shunt reactor and the effect of iron core nonlinearity, a new model of single-phase shunt reactor used for harmonic analysis and computer simulation is presented. It presented shunt reactor by a simple equivalent circuit consisting of an impedance representing the leakage flux losses in series with a parallel combination of a nonlinear inductance (accounting for the saturation of the iron core) and a nonlinear resistance (accounting for the iron loss).The nonlinear impedance is calculated by the and curves which had been used for modeling of transformer excitation impedance. The result of simulation in PSCAD/EMTDC using the parameters of shunt reactor in China's UHV AC Pilot Project have proved that this model accurately reflect the nonlinear characteristics of shunt reactor, which is the prerequisite to complete the simulation model of UHV AC transmission system and analyze the harmonic characteristic of the system.
