Sefe e Sebetsang ea Harmonic (AHF)—Mekhahlelo e Meraro
Kakaretso ea Sehlahisoa:
Li-filter tse sebetsang tsa harmonic (AHF) ke karabo e phethahetseng mathateng a boleng ba motlakase a bakoang ke ho sotha ha sebopeho sa maqhubu, matla a tlase, liphetoho tsa motlakase, ho feto-fetoha ha motlakase le ho se leka-lekane ha mojaro bakeng sa mefuta e mengata ea likarolo le lits'ebetso. Ke mofuta oa li-filter tse sebetsang tsa motlakase (APF) tse sebetsang hantle, tse nyane, tse tenyetsehang, tse nang le modular le tse theko e tlaase tse fanang ka karabelo ea hang-hang le e sebetsang mathateng a boleng ba motlakase lits'ebetsong tsa motlakase tse tlase kapa tse phahameng. Li nolofalletsa bophelo ba lisebelisoa nako e telele, ts'epo e phahameng ea ts'ebetso, bokhoni bo ntlafetseng ba sistimi ea motlakase le botsitso, le tahlehelo e fokotsehileng ea matla, ho latela maemo a mangata a boleng ba motlakase le likhoutu tsa grid.
Li-AHF li felisa ho sotha ha sebopeho sa maqhubu ho tsoa meroalong e kang li-harmonics, li-harmonics tse fapaneng le ho notch, le li-voltage tsa harmonic tse bakoang ke maqhubu a harmonic, ka ho kenya hona joale e sothehileng ea boholo bo tšoanang empa e fapane le mohato tsamaisong ea motlakase. Ho phaella moo, li-AHF li ka sebetsana le mathata a mang a 'maloa a boleng ba motlakase ka ho kopanya mesebetsi e fapaneng sesebelisoa se le seng.
