This paper presents the overview of studies on the abnormal oscillations which have been occurred in the power transmission systems in Japan. It also focuses on the recent studies of the dynamics of the subharmonic oscillation of order 113 in a nonlinear three-phase circuit which is the fundamental model of the series-compensated transmission line.

This paper presents the impact study of apparent reactance injected by series Flexible AC Transmission System (FACTS) i.e. Thyristor Controlled Series Reactor (TCSR) on the measured impedance of a 400 kV single electrical transmission line in the presence of phase to earth fault with fault resistance. The study deals with an electrical transmission line of Eastern Algerian transmission networks...

Overview of fault location techniques for HV (EHV) transmission lines as well as for distribution networks is presented. One-end and two-end fault location for traditional uncompensated transmission lines is considered first. The presented two-end fault location is based on unsynchronised measurements at the line terminals. Then the technique with phase co-ordinates approach is utilised for loc...

In this paper, performance evaluation of different schemes for location of fault in series compensated transmission lines are presented. A fault location algorithm using two end measurements and another fault location algorithm using one end measurements for transmission lines with series compensator at midpoint are simulated and results are obtained. Both the schemes are compared on the basis ...

This paper presents an efficient method based on bus power injection for transmission line compensation. In this method, the load flow solution is first obtained using specified generations and loads. The terminal buses connecting the line to be compensated and the compensation level are identified. The differences of the line flows before and after compensation are injected in or out of the tw...

Due to the rising power demand and increasing population worldwide, electrical power networks have been extensively growing and striving to satisfy the escalating loads. This necessitates the need for using Flexible AC Transmission System (FACTS) devices which have become indispensable during normal and abnormal operating conditions. This paper investigates the impact of using series FACTS devi...

With the increasing demand of electric power supply, the necessity to transmit more power has become the need of the hour. The excess power can be transferred by building new infrastructure (costly and time taking) or by using series compensation (relatively cheaper and faster alternative). Series compensation is a technique in which line inductance is compensated by placing a capacitor in seri...
