The Interline Power Flow Controller (IPFC) is a voltage source converter based Flexible AC Transmission System (FACTS) controller for series compensation and power flow management among substation's multiline transmission systems. Individual Voltage Source Converters (VSC) can inject reactive that be adjusted to manage active in line. This VSC used convert DC the kept constant entire process. I...
The FACTS (Flexible AC Transmission Systems) devices have great use in the Electric Power System (EPS) for dynamic control of active and reactive powers system. This work deals with a comparative analysis between effects caused distance protection transmission lines (TLs) by two these devices: STATCOM (Static Synchronous Compensator) SSSC Series Compensator). objective is to verify how connecti...
a novel ultra wideband microstrip bandpass filter using radial stub loaded resonator and interdigital coupled lines is presented in this paper. the radial stub loaded resonator and decagonal patch form a resonator named m to create tuneable multiple notches in the passband for suppression wlan interference. to realize sharp roll-off, two adjustable transmission nulls are located at the lower an...
<span lang="EN-US">The present work investigates the flexible AC transmission system (FACTS) device's role to improve voltage stability for a distribution network of various types loads. Our analysis was based on using static synchronous compensator (STATCOM) device over test system. Firstly, detailed description mathematical model used in our is presented. Then we studied effect inductiv...
In this paper a novel method for finding the fault zone on a Thyristor Controlled Series Capacitor (TCSC) incorporated transmission line is presented. The method makes use of the Support Vector Machine (SVM), used in the classification mode to distinguish between the zones, before or after the TCSC. The use of Discrete Wavelet Transform is made to prepare the features which would be given as th...
cooperative object manipulation control of rigid-flexible multi-body systems in space is studied in this paper. during such tasks, flexible members like solar panels may get vibrated that in turn may lead to some oscillatory disturbing forces on other subsystems, and consequently produces error in the motion of the end-effectors of the cooperative manipulating arms. therefore, to design and dev...
abstract the problems caused by the traditional system of criminal justice (which are based on remuneration and rehabilitation) such as, lack of attention to victim’s rights and position and society, underlie the emergence of restorative justice which had the victim-centered perspective, with respect to the role of the offender and participation of civil society. meanwhile, criminal mediation ...
One of the best flexible AC transmission system (FACTS) is unified power flow controller (UPFC). As it gets more benefit from both real and reactive transfer, used in for controlling transmitted power. The UPFC controls on side system. When as well set tries to follow command by using proportional integral (PI) controller. But some systems PI controllers cannot produce proper due oscillations. ...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
The electrical power industry experiences nowadays a significant need in modern techniques for increasing the capability of power transmission systems. The reason for this lies in growing power flows, caused by ris¬ ing power consumption, and in the deregulation of the electrical market, where power flows should be more flexible. These factors demand more transmission capability from the existi...
