Control System for Distributed Generation in Low Voltage Network Systems
Published by Robert JĘDRYCHOWSKI, Klara SEREJA, Politechnika Lubelska, Katedra Sieci Elektrycznych i Zabezpieczeń, Poland Abstract. Implementation of prosumer energy generation to low-voltage network systems involves both benefits and technological problems concerning the grid operation. Electricity generation in LV network systems is of a distributed and quite unpredictable character. In those systems, solar PV installations, whoseContinue reading “Control System for Distributed Generation in Low Voltage Network Systems”

Autotransformers for Power Systems
Published by Waldemar ZIOMEK, PTI Manitoba Inc., Winnipeg, MB, Canada Abstract. When the primary and secondary voltages are obtained from the same winding, or from two windings which are galvanically connected, such a transformer is called an autotransformer. The paper will focus on fundamentals, design and applications of autotransformers of core-type design. The selected problemsContinue reading “Autotransformers for Power Systems”

An Experimental Study of Wind Data of a Wind Farm in Kosovo
Published by Sabrije OSMANAJ1, Bukurie HOXHA2, Rexhep SELIMAJ2*1Faculty of Electrical and Computer Engineering, , 2Faculty of Mechanical Engineering, University of Pristina, Republic of Kosovo Abstract. In Kosovo, 97% of energy is generated from lignite-fired power plants. Apart from the energy generation, the combustion process emits around 8000 ktCO2/yr and 1.5 Mt of ash in theContinue reading “An Experimental Study of Wind Data of a Wind Farm in Kosovo”
Application of Additional Grounded Wires in High Voltage Overhead Power Lines to Reduce the Intensity of Electric Field Generated by Phase Wires
Pubsliehd by Jacek GUMIELA1, Dariusz SZTAFROWSKI1 Politechnika Wrocławska, Katedra Energoelektryki (1) Abstract. To minimize interference with the environment it is important to make every effort already at the design stage to spare the trouble associated with additional investment later on. Due to the value of land in urban areas, it is beneficial to take necessaryContinue reading “Application of Additional Grounded Wires in High Voltage Overhead Power Lines to Reduce the Intensity of Electric Field Generated by Phase Wires”
