Taifuka da SIL

Surge Impedance Loading (SIL) yana nufin kyau na kayan shiga mai amfani da shi wanda ya dacewa da taifukan surge impedance na kayan shiga.

Surge Impedance

Surge Impedance yana cikin wurin da ake kawo reactive capacitance da inductive reactance suka tafara ba zama zero.

Kayan shiga masu fadada (> 250 km) suna da inductance da capacitance mafi yawan sadarwa. Idan an sanya, capacitance yana bayar reactive power zuwa kayan shiga, kuma inductance yana jira ita.

Idan muna ci gaba da tafaran reactive powers bi, muna samun wannan equation

Capacitive VAR = Inductive VAR

Daga baya,

V = Phase voltage

I = Line Current

Xc = Capacitive reactance per phase

XL = Inductive reactance per phase

A nan, idan muna sauya

Daga baya,

f = Frequency of the system

L = Inductance per unit length of the line

l = Length of the line

Saboda haka muna samun

Wannan adadin da ya fi yawa na resistance shine Surge Impedance. Yana iya cewa shi ne load mai resistance kawai, wanda idan ake sanya a kan tsakiyar kayan shiga, reactive power da capacitance ta bayar zai zama da inductive reactance ta jira.

Shi ne Characteristic Impedance (Zc) na kayan shiga da ba da loss.

Siffar da Kayan Shiga

• Siffafin da ke kusa da inductance da capacitance sun fiye a fahimtar siffar da kayan shiga.

• Siffafin da ke kusa da inductance da capacitance sun fiye a fahimtar siffar da kayan shiga.

• Takaitaccen characteristic impedance da load impedance sun taimaka a fahimtar yadda SIL taimaka wajen zama shiga da kyau.

Aiki na Tsarin

SIL yana da muhimmanci wajen kwalbar kayan shiga don inganta tasiri na voltaji da shiga da kyau.
