Efficiency study of the reactive shunt compensation device in power lines

Abstract

We consider the devices for reactive shunt compensation and simulated their use in a real energy facility.

Assessment of the Impact of Per Unit Parameters Errors on Wave and Output Parameters in a Transmission Line

“…A thorough analysis of the above diagrams may be used to construct optimal high voltage cables used in the ignition systems of spark−ignition engines, where the most important parameter is the U 2 voltage modulus [3,4,10,20].…”

“…Their values are specified as Ω/m, S/m, H/m, and F/m [7][8][9]. It is conventionally assumed that if l is greater than 0.1 λ, or the transmission of impulse signals with a short rise time, as is the case in high voltage cables of spark ignition engines [3,4,6,10], then such a line should be treated as a circuit with distributed parameters. This paper shall examine the properties of a homogeneous line, whose primary parameters are uniformly distributed along the line [7,9].…”

“…A receiver with impedance Z 2 is connected to output terminals 2-2 . At any point on the line distant by x 1 from the beginning of the line, the voltage is u(x 1 ,t) and the current is i(x 1 ,t), in which case for the input terminals x = 0, and for the output terminals x = l [3,10,11].…”

Features of electroosmosis usage for drying and moisture protection of electrical equipment

“…Potential difference from EOD and EOMP devices is supplied on the winding conductors and the transformer housing. Therefore, EOD and EOMP for transformers require special consideration [23].…”

Modelling of emergency modes with FACTS devices installed

“…Active electro-technical network equipment (FACTS) is capable of flexibly change the characteristics of electric power transmission or conversion in order to optimize grid modes at once according to several criteria: throughput, technological loss level, stability, redistribution of power flows, power quality, etc. [1] FACTS devices enable not only successful compensation of reactive power in the power grid, but also adequate response to abnormal conditions in it. Thanks to these parameters, flexible AC transmission systems are one of the best devices to be installed in line.…”
