https://matjournals.co.in/index.php/JEPSE <p>Journal of Electrical and Power System Engineering is a print e-journal focused towards the rapid Publication of fundamental research papers on all areas of electrical and power system engineering. Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics, and electromagnetism. And Power engineering, also called power systems engineering, is a subfield of electrical engineering that deals with the generation, transmission, distribution and utilization of electric power. Focus and Scope covers Thermodynamics, Electrical machines and design, Digital Electronics, Electrical Engg. Materials Instrumentation, Electrical network and communication systems, Power and control systems, Numerical Analysis, Microprocessors and Interfacing</p> en-US Journal of Electrical and Power System Engineering (e-ISSN: 2582-5712) https://matjournals.co.in/index.php/JEPSE/article/view/5505 <p>An UPFC for the FACTS devices in a multi-machine power system to damp the <br />electromechanical oscillations. The unified power flow controller is designed based on the <br />PI, PID and POD controllers. The amplification part of the controller is modified depends <br />upon the power system conditions. The performance of the controllers is simulated over a <br />wide range of operating conditions and disturbances and its robustness is proved.</p> M. Dinesh J.

Because these virtually <br>unbound electrons are free to leave their respective atoms and float around in the space <br>between adjacent atoms, they are often called free electrons. In other types of materials such <br>as glass, the atoms' electrons have very little freedom to move around. While external forces <br>such as physical rubbing can force some of these electrons to leave their respective atoms <br>and transfer to the atoms of another material, they do not move between atoms within that <br>material very easily. This relative mobility of electrons within a material is known as electric <br>conductivity. Conductivity is determined by the types of atoms in a material (the number of <br>protons in each atom's nucleus, determining its chemical identity) and how the atoms are <br>linked together with one another. Materials with high electron mobility (many free electrons) <br>are called conductors, while materials with low electron mobility (few or no free electrons) <br>are called insulators. A conductor is something which allows electricity to flow through. An <br>example of a conductor is: scissors, paper clip, aluminum foil etc. These materials are made <br>up of atoms whose electrons can move away freely.</p> Vishakha Garg Copyright (c) 2024 Journal of Electrical and Power System Engineering (e-ISSN: 2582-5712) 2015-10-24 2015-10-24 1 3 9 12
