Tandem ( Series ) Connection of Two Port Network
Two networks are
connected in series such that output of one network is connected to input of
another network, such type of connection is called as Tandem connection of two
port network. It is considered that network 1 is connected to network 2 in
tandem.
Let
A1, B1, C1 and D1
– Constant of network 1
A2, B2, C2 and D2
– Constant of network 2
Network 1
VS = A1V’ + B1I’……. ( 1 )
IS = C1 V’ + D1 I’……..( 2 )
Where
VS =
Sending end voltage
IS =
Sending end current
V’ = Receiving end
voltage of network 1
I’ = Receiving end
voltage of network 1
Network 2
V’= A2VR + B2IR……. ( 3
)
I’
= C2VR + D2 IR……..( 4 )
Where
V’ = Sending end
voltage
I’ = Sending end
current
VR =
Receiving end voltage of network 2
IR =
Receiving end voltage of network 2
Substitute
equation ( 3 ) and ( 4 ) into equation ( 1 ) and ( 2 )
VS = A1
( A2VR + B2IR ) + B1 ( C2VR + D2 IR
)……. ( 5 )
VS =
A1A2 VR + A1 B2IR + B1 C2VR + B1D2 IR
VS
= ( A1A2 + B1 C2 )VR + ( A1 B2 + B1D2 )IR ….. ( 6
)
Compare equation (
6 ) with Vs = AVR + BIR
A = A1A2 + B1 C2
B = A1 B2 + B1D2
IS = C1
( A2VR + B2IR ) + D1 ( C2VR + D2 IR
)
IS = C1
A2VR + C1B2IR + D1 C2VR + D1D2 IR
IS = ( C1
A2 + D1 C2 ) VR + ( C1B2 + D1D2 ) IR…….( 7 )
Compare equation (
7 ) with Is = CVR + DIR
C = C1 A2 + D1 C2 and
D = C1B2 + D1D2

ABCD Parameters of Two Parallel Transmission Line or Networks
Let us consider
that the two-transmission line or network is in parallel. In this theory, we
find out equivalent A, B, C and D parameters of parallel networks or
transmission line
Let

VR = Receiving end voltage to neutral
Analysis of Long Transmission Line ( Rigorous Method of Solution of Long
Transmission Line )
A long transmission line is considered as infinite length. It is not possible to calculate all the parameters for infinite long length therefore here we consider only small length dx in order to evaluate whole line. Let us consider that length of line is dx at x distance from receiving end of the transmission line.
ABCD parameters of medium transmission line : Nominal
π method
The total capacitance of the transmission line is divided into two parts, half at the sending end side and another half at the receiving end side in the nominal π method. All the parameters are given considering three phase transmission line.
