[ 1 ] - مدیریت هوشمند انرژی در سیستم حمل و نقل برقی
آلودگی محیط زیست و کمبود انرژی به عنوان بحران های جدی ، پژوهشگران و صنعت گران را بر آن داشته تا به دنبال راهکار هایی مناسب با هدف مدیریت انرژی باشند . صنعت حمل و نقل برقی به ویژه سیستم های مترو درون شهری و ایستگاه های شارژ خودرو های الکتریکی از جمله مصرف کنندگان بزرگ انرژی برای شبکه برق سراسری محسوب می‌گردند ، به گونه ای که مصرف این بار‌ها ، معمولاً با پیک تقاضای برق از شبکه اصلی همزمان می...
[ 2 ] - Fuzzy Logic-Based Vector Control of Permanent Magnet Synchronous Motor Using Stacked Matrix Converter for Railway Traction Applications
Recently, Permanent Magnet Synchronous Motors (PMSMs) have been widely accepted and employed in traction and railway transportation applications due to their various advantages such as small inertia, high efficiency and high torque density. In this paper, in order to use these motors as traction drives in an effective way, the vector control scheme is employed. In this strategy, the stator curr...
[ 3 ] - Applying Frequency Response method for contact Rails Fault Diagnosing in Ungrounded Electrical Railway System
Abstract General faults in regular electrical railways system could be detect by implementing the specific protection functions such as ground fault or sensitive earth fault. Otherwise, in ungrounded electrical railway systems which using both feeding and return contact rail at the same time, fault detection cannot done with above-mentioned function. Due to recent growth in electrical railway ...
[ 4 ] - An Efficient Strategy for Power Rating Reduction of Back-to-Back Converters Used in Railway Power Conditioner
One of the most common solutions to deal with the power quality issues of electrical railway systems is employing Railway Power Conditioner (RPC). In the conventional mode of operation, the RPC power rating deployed in every Traction Power Substation (TPS) is significantly large. This paper mainly focuses on the power rating reduction of RPC through presenting a novel combinatorial compensation...
[ 5 ] - Analysis of Semi-Bogie Based Propulsion System Used in Tehran Metro's trains in Degraded Mode of Operation
During the supply process of rolling stocks for metro systems, the propulsion system of trains in terms of separate power and control scheme should be selected based on the Reliability, availability, maintainability, and safety (RAMS) parameters along with some expected indexes in operation plan. This means that, in addition to undeniable control and operation advantages of a train that are equ...
