Analysis of Catenary Short Circuit Case in a 1500 V DC Fed Railway Line with a Dynamic Model Algorithm

Abstract

Electricity supply railways in transportation systems have a high rate of investment preference. In the case of electric railways, the electrification of the electrification system is essential for the continuity of the operation. Before its design, the features of the system are simulated and the capacity, performance and failure conditions of the electrification system are tested. It is of utmost importance to analyze fault conditions and take possible measures for business continuity. In this study, having created a dynamic model, a 1500 V DC powered urban subway line has been simulated. While the algorithm developed for dynamic structure is explained, its simulation results are given. For the study, the analysis of a possible short circuit condition in the catenary system has been investigated. Using the data of a rail system line with 7 substations, the possible effects of the short circuit condition have been evaluated over the graphs. Measures to be taken from the results obtained are given.

Dinamik Model Algoritması ile 1500 V DC Beslemeli Bir Metro Hattında Katener Kısa Devre Durumunun Analizi

Abstract

Ulaşım sistemleri içinde elektrik beslemeli demiryolları yatırım tercihi olarak yüksek bir orana sahiptir. Elektrikli demiryollarında ise elektrifikasyon sisteminin elektrik verme görevini kusursuz olarak yerine getirebilmesi işletme sürekliliği için esastır. Tasarım öncesinde elektrifikasyon sistemi benzetimi yapılarak sisteme ait kapasite, performans ve arıza durumları test edilmektedir. İşletme sürekliliği için arıza durumlarının analizi ve olası tedbirlerin alınması büyük önem taşımaktadır. Bu çalışmada dinamik bir model oluşturularak 1500 V DC beslemeli bir şehiriçi metro hattının benzetimi yapılmıştır. Dinamik yapı için geliştirilen algoritma anlatılarak benzetim sonuçları verilmiştir. Çalışma için katener sisteminde olası bir kısa devre durumunun analizi araştırılmıştır. 7 trafo merkezi bulunan bir raylı sistem hattına ait veriler kullanılarak kısa devre durumunun olası etkileri grafikler üzerinden değerlendirilmiştir. Elde edilen sonuçlar üzerinden alınması gereken tedbirler verilmiştir.
