Research ArticleOpen accessIn the abstractA GA Based Transmission Network Expansion Planning Considering Voltage Level, Network Losses and Number of Bundle LinesS. Jalilzadeh, H. Shayeghi, M. Mahdavi, H. HadadianTransmission Network Expansion Planning (TNEP) was studied considering voltage level, network losses and number of bundle lines using decimal codification based genetic algorithm (DCGA). TNEP determines the characteristic and performance of the future electric power network and directly influences the operation of power system. Up till now, various methods have been presented for the solution of the Static Transmission Network … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,585 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDynamics at Classical DistributionRelly Victoria Virgil PetrescuClassical distribution is the most used in rigid memory mechanisms adapted to four-stroke internal combustion engines such as Otto or diesel, as it was designed by Otto more than 150 years ago, without essential changes from its conception and up today. Since it was not yet possible to introduce the electric car to the industrial scale and today we have … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 26 Apr 2019 · 6,394 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordExperimental Study of Electromagnetic Environment in the Vicinity of High Voltage LinesWafa Tourab, Abdesselam Babouri, Mohamed NemamchaProblem statement: Several studies have investigated the impact of electromagnetic field generated by high voltage power lines on environment. The evaluation of electric and magnetic field quantities are of paramount interest in the characterization of electromagnetic environment of the proposed line. The purpose of this study was to analyze the behavior of electromagnetic fields generated by power lines in an … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 12 Jul 2011 · 8,316 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Effect of the Harmonics, the Fault Location and the Fault Resistance on the Performance of the Impedance-Type Distance RelayA. S. Khraiwish, M. Alshamasin, R. Kassasbeh et al.One of today's trends is continuously increasing the number and the power ratings of the non-linear loads connected to the electric power systems. These non-linear loads, such as power-electronic converters, are the main source of the harmonics that affect the performance of the impedance-type distance relays. It was found that, in the presence of harmonics, undesired operation of such type … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,567 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDesign of Robust UPFC Controller Using H∞ Control Theory in Electric Power SystemSeyed Abbas Taher, Shahabeddin Akbari, Ali Abdolalipour, Reza HemattiAn industrial plant, such a power system, always contains parametric uncertainties. In the design of a controller the uncertainties have to be considered. Otherwise, if the real plant differs from the assumed plant model, a controller, designed based on classical controller design approaches, may not ensure the stability of the overall system. In this paper design of robust control for … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,090 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordComparison of Different Control Strategies in GA-Based Optimized UPFC Controller in Electric Power SystemsSeyed Abbas Taher, Reza Hematti, Majid NematiThis study presents a study of the application of a Unified Power Flow Controller (UPFC) to control power transmission, generator terminals voltage and better damping of Low Frequency Oscillation (LFO) in Single-Machine Infinite-Bus (SMIB) power system. The UPFC integrates properties of both shunt and series compensations and can effectively alter power system parameters in a way that increases power transfer … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,599 accessesView PDF Cite
