Distributed Power Flow Controller is a new device within the family of FACTS. The DPFC has the same control capability as the UPFC, but with much lower cost and higher reliability. This paper addresses one of the applications of the DPFC namely compensation of unbalanced currents in transmission systems. Since the series converters of the DPFC are single phase, the DPFC can compensate both acti...

But first concerning controversies there is also a controversy concerning the use or non-use of baluns, and which balun to use. Since many antenna types are balanced, and present day HFTPA’s are unbalanced, and, since the preferred method of feeding antennas is to use coaxial cable, rather than 2-conductor balanced transmission line, a balun should, often must be used in the overall antenna sys...

AC transmission system is major part which links the generation and distribution.The transmission system is subjected to stability problems,which occurs due to abnormal conditions like faults,over voltages.These limit the transmission capability.Power systems often suffer from weakly damped swings between synchronous generators. The main objective of this paper is to enhance the transient stabi...

In this paper, the design of three stage hybrid architecture for controlling and preventing certain disturbances caused in transmission lines is studied. The transmission lines of modern power systems are equipped with WSN (Wireless Sensor Network). Since WSNs are capable of cost efficient monitoring over a wide range of geographical areas. Consequently monitoring of mechanical parameters of tr...

In Part I of this work, analysis of uniform multi-conductor transmission line networks is performed on travelling-wave basis, via “quasi-TEM” approach. Narrowband interpretation of the modal theory in the time domain and quantification of the multiple reflections effect are both included. Theoretical demonstration and analytical formulation are provided, along with guidelines towards computatio...

In Part I of this work, travelling-wave modelling of uniform multi-conductor transmission line networks was analytically established with direct applicability to narrowband transmission, covering any network formed of lossy (in the general case), diagonalisable uniform multi-conductor transmission lines of either distinct or degenerate eigenvalues. As the whole work applies especially in the fi...

In an unregulated electricity generation market, the capacity of transmission lines will determine the degree to which generators in different locations compete with one another. We show, however, that there may be no relationship between the effect of a transmission line in spurring competition and the actual electricity that flows on the line in equilibrium. We also demonstrate that limited t...
