Takaitaccen Synchronous Condenser

Synchronous condenser yana nufin motori mai tsari wanda ya yi aiki a taka fagen mutuwa, amma an yi amfani da shi don inganta power factor na karkashin sana'a.

Inganta Power Factor

Idan saboda mutuwar da ke cikin karkashin sana'a, karkasha ta hankali current Ithree phase synchronous motorL daga masu aiki a matsayin lagging angle θL zuwa voltage. Duk da haka, motorin ta hankali IM daga masu aiki a matsayin leading angle θM.

Duk da haka, current na gaba da aka hankali daga masu aiki shine vector sum na load current IL da motor current IM. Current na gaba I da aka hankali daga masu aiki tana da angle θ zuwa voltage. Angle θ yana da kadan mafi yawan angle θL. Saboda haka, power factor na karkashin cosθ yana da kadan mafi yawa a matsayin power factor cosθL na karkashin bayan an sa shi a karkasha synchronous condenser.

Synchronous condenser yana da hanyar da ya fiye don inganta power factor musamman da static capacitor bank. Amma, idan karkashin kai ita da 500 kVAR, ba zai zama tattalin arziki da capacitor bank. Don karkashin mafi yawa, ana amfani da synchronous condensers, amma don karkashin mafi yawan kai, ana amfani da capacitor bank.

Wannan babbar tushen da synchronous condenser ke da shi shine cewa an iya kawo karfin power factor da karamin kyau. Duk da haka, static capacitor bank zai iya inganta power factor a wurare, bai iya kawo karfin fina-finai ba. Short circuit withstand-limit na armature winding na synchronous motor yana da ma'ana mafi yawa.

Amma, system na synchronous condenser na da wasu abubuwan da ba su da kyau. Systema ba ce ta sama, domin motorin synchronous yake da yin aiki na yau da kullum.

Motorin synchronous da ba da mu'amala ba yana hankali current da ke leading a 90o(electrical).
