Papiso ea motlakase o tloaelehileng oa maqhubu a mahareng a KGPS, phepelo ea motlakase ea maqhubu a mahareng a IGBT le phepelo e ncha e bolokang matla ea KGPSSD ea maqhubu a mahareng.

1. Tloaelehileng KGPS SCR parallel IF phepelo ea motlakase

Melemo ke: e ‘nile ea sebelisoa ka ho fetisisa lilemong tse mashome a seng makae tse fetileng, theko e tlaase, tlhokomelo e bonolo, le lisebelisoa tse theko e tlaase.

Bothata ke: tšebeliso e matla ea matla, tšebeliso ea motlakase ka thane e le ‘ngoe ea tšepe e qhibilihisitsoeng e feta likhato tse 700. Matla a lokisoa ka ho lokisa motlakase oa DC, matla a matla a tlase (≤0.85), ‘me ho na le tšitiso ea harmonic, e nang le phello e fapaneng ea ts’ebetso ea capacitor ea puseletso ea matla a sebetsang ka har’a seteishene.

2. Phepelo ea matla a maqhubu a mahareng a IGBT

Melemo ke: tokiso e amohela tokiso ea maqhubu a felletseng, ‘me mokhoa oa filthara oa LC o entsoeng ka li-capacitor le li-inductors o etsa hore matla a fihle kaholimo ho 0.96, ha e le hantle ntle le tšitiso ea harmonic. Karolo ea inverter e amohela mokhoa oa ho sebetsa oa letoto la inverter, ‘me mojaro o sebetsa tlas’a boemo ba matla a phahameng le a tlaase,’ me tahlehelo ea koporo e nyenyane, e ntlafatsang haholo ts’ebetso. Tšebeliso ea motlakase ka thane e le ‘ngoe ea tšepe e qhibilihisitsoeng e ka tlase ho likhato tse 600.

Bobebe ke: phepelo ea motlakase ea maqhubu a mahareng a IGBT e hloka tikoloho e phahameng ea ho sebetsa.

3. Letoto le lecha la ho boloka matla la KGPSSD thyristor la maqhubu a mahareng a phepelo ea motlakase

KGPSSD thyristor intermediate frequency power supply e rua melemo ea lihlahisoa tse peli tse ka holimo, e amohela phepelo ea motlakase ea tokiso e felletseng, ‘me rectifier e lula e le maemong a felletseng (e lekanang le tokiso ea diode) nakong ea ts’ebetso eohle ea ts’ebetso; matla a lisebelisoa a lula a le boemong bo phahameng ka ho fetisisa (≧0.96). Ha e hlahise li-harmonics tse phahameng, ha e na tšilafalo ho marang-rang a matla, ‘me ha e ame ts’ebetso ea li-capacitor tsa matšeliso a matla a substation reactive power. Ha e bapisoa le lisebelisoa tse tloaelehileng tsa thyristor parallel intermediate frequency frequency, e boloka hoo e ka bang 15%. Ho feta moo, likarolo li theko e tlaase, ho bonolo ho reka le ho lokisoa habonolo.
