Takaitaccen Tashar Tushen Tashar

Takaitaccen tashar tushen tashar yana nufin tushen da tsari kimanin 80 km (50 miles) zuwa 250 km (150 miles).

Takaitaccen tashar tushen tashar yana nufin tushen da tsari mai kyau da 80 km (50 miles) amma ya fi 250 km (150 miles). Duk da cewa tushen mafi tsari ba, tashar tushen takaitaccen tashar yana da muhimmanci kuma shi ne ya danganta. Saboda haka, tsohon tushen shi zai iya dubawa (wannan shine halayen da ke faruwa a tushun mafi tsari). Wannan tsohon tushen shi ana gudanar da dalilin “Y” daga ABCD parametere.

ABCD parametere na takaitaccen tushen tushen tashar suna dogara da tsohon tushen mai tsawo da tsohon tushen mai tsawo. Wanannan parametere suna iya dogara da modelon da uku:

• Nominal Π representation (nominal pi model)

• Nominal T representation (nominal T model)

• End Condenser Method

Zan yi bayani mai zurfi game da wannan modelon da aka bincika, sannan za ku dogara ABCD parametere na takaitaccen tushen tushen tashar.

Muhimmancinta Tsohon Tushen

Tsohon tushen yana da muhimmanci a takaitaccen tushen tushen tashar saboda tashar tushen.

Nominal Π Mode

A cikin nominal Π representation (ya’ni nominal pi model), tsohon tushen mai tsawo ana sa ta hanyar masu circuit wanda tsohon tushen shi ne suke a kanafin circuit. Kamar yadda aka fahimta daga diagram na Π network, tsohon tushen mai tsawo ta kasance suka zama biyu, kuma min daga biyu ne Y/2 ana sa ta hanyar masu circuit wanda tsohon tushen shi ne suke a kanafin circuit.

Rukanin circuit wanda aka dogara yana nufin symbol Π, kuma saboda haka, an kiranta nominal Π representation na takaitaccen tushen tushen tashar. Ana amfani da shi don dogara parametere na circuit da kuma yi analysis na tashar.

Hakan, VS shine voltage na masu supply, VR shine voltage na masu receiving. Is shine current na masu supply, IR shine current na masu receiving. I1 da I3 shine currents na tsohon tushen, I2 shine current na tsohon tushen mai tsawo Z.

Sannan za a yi KCL, a node P, muna samu.

Duk da cewa za a yi KCL, a node Q.

Sannan za a koyar equation (2) zuwa equation (1)

Sannan za a yi KVL zuwa circuit,

Koyar equation (4) da (5) zuwa standard ABCD parameter equations

Muna dogara ABCD parameters na takaitaccen tushen tushen tashar kamar:

Nominal T Model

A cikin nominal T model na takaitaccen tushen tushen tashar, tsohon tushen mai tsawo ana sa ta hanyar masu circuit, kuma tsohon tushen mai tsawo ta kasance biyu da za su sa ta hanyar masu circuit. Rukanin circuit wanda aka dogara yana nufin symbol na capital T, kuma saboda haka, an kiranta nominal T network na takaitaccen tushen tushen tashar, kamar yadda ake fahimta a diagram.

Hakan, Vt networks da Vr shine voltages na masu supply da receiving respectively, and

Is shine current na masu supply end.

Ir shine current na masu receiving end of the circuit.

Za a yi M node a kanafin circuit, kuma drop at M, za a bayyana da Vm.

Sannan current na masu sending end yana ce,

Koyar value of VM zuwa equation (9) muna samu,

Duk da cewa za a koyar equation (8) da (10) zuwa standard ABCD parameter equations,

Parametere na T network na takaitaccen tushen tushen tashar suna ce

ABCD Parameters

ABCD parameters na takaitaccen tushen tushen tashar suna dogara da tsohon tushen mai tsawo da tsohon tushen mai tsawo, muhimmiyar don analysis da design da tushen.

End Condenser Method

A cikin end condenser method, capacitance na tushen ana tsakiyar a kan masu receiving end. Wannan method yana iya kawo karfin capacitance
