Rezumat | ||||||
The paper deals with elaboration of hexaphase symmetrical components filters and their modeling to create microprocessor-assisted relay protection of self-compensating power lines. The theory is presented and the basic principial electrical schemes and mathematical models in the Matlab/Simulink of the filters of the hexaphase symmetric components are elaborated. The results of their simulation and testing at the computer are presented. The obtained results demonstrate the possibility of creating in the base on the elaborated filters of hexaphase symmetrical components the modern, efficient and high-sensitivity microprocessor-assisted relay protection of self-compensating power lines. What reacted not to phase electrical values, but symmetrical components of them. |

Este prezentată teoria și sunt elaborate schemele electrice principiale și modelele matematice în Matlab/Simulink a filtrelor cu componente simetrice hexafazate. Sunt prezentate rezultatele simulării și testării lor la calculator. Rezultatele obținute demonstrează posibilitatea creării în baza filtrelor cu componente simetrice hexafazate a unei protecții eficiente, bazată pe microprocesor de înaltă sensibilitate, care reacționează la diferite deteriorări ale liniilor electrice cu autocompensare nu la mărimi electrice de fază, ci la componentele simetrice.</p></dc:description> <dc:identifier>10.52326/jes.utm.2022.29(2).04</dc:identifier> <dc:source>Journal of Engineering Sciences (2) 46-53</dc:source> <dc:subject>modeling of current filter</dc:subject> <dc:subject>power transmission line</dc:subject> <dc:subject>relay protection</dc:subject> <dc:subject>transfer capacity of the line</dc:subject> <dc:subject>modelare filtru de curent</dc:subject> <dc:subject>linie electrică de transport</dc:subject> <dc:subject>protecție prin relee</dc:subject> <dc:subject>capacitatea de transport a liniei</dc:subject> <dc:title>Development of six-phase symmetrical components filters for self-compensating power lines</dc:title> <dc:type>info:eu-repo/semantics/article</dc:type> </oai_dc:dc>
