描述
TheDecoupling Line块实现了单相分布式参数线模型，该模型传输了进入其保护端口到相关端口的电信号Decoupling Lineblock in your model. The twoDecoupling Line块形成一对，代表单相传输线的发送和接收末端。
The behavior of the pair of blocks is equivalent to using oneDistributed Parameters Lineblock:
Refer toDistributed Parameters Line有关用于表示波传播现象和线端反射的方程式的详细描述。
Use theDecoupling Lineblock pairs when you want to model a transmission line with no physical electrical connections between the send and receive ends of the line. This technique is used, for example, in applications where a large network is decoupled into smaller sections that are simulated into different subsystems or models with no electrical connections between them. This decoupling technique is often used to model complex electrical networks on multi-core real-time computers, or to allow faster simulation of large networks.
两对中的块可以通过使用配对IDparameter, which transmits the electrical signal information travelling from one terminal to the other using internal Simulink®去和从blocks or connecting the blocks with Simulink signals.
The parameters of eachDecoupling Line一对中的块必须是相同的，并且对应于您将输入的参数Distributed Parameters Lineblock. For example, to model a 100 km transmission line with the given R, L, and C values, use twoDecoupling Line块的长度为100 km，相同的R，L和C值。
To model a transmission line in your model, add twoDecoupling Lineblocks to your model and set the block parameters to the same values. Alternatively, use the Specify Decoupling Lines App to find, select, and automatically replace existingDistributed Parameters Line与等效对的模型中的块Decoupling Line块。For more information, seeSpecify Decoupling Lines。

Parameters
Parameters
线长度（km）— Transmission line length
100（默认）|正标量
传输线长度，以公里为单位。因为该块与另一个一起使用Decoupling Lineblock, enter the same line length in each of the two blocks; do not split the value between each of the two blocks. For example, to model a 100 km line, specify 100 in each block, not 50 in one block and 50 in the other block.
用于R L C规格（Hz）的频率— Line frequency
60（默认）|正标量
Specify the frequency used to compute the per-unit length of the resistance (R), inductance (I), and capacitance (C) matrices of the line model.
单位长度的电阻（欧姆/公里）— Line resistance
0.01273（默认）|正标量
Resistance R per unit length, in ohms/km (Ω/km).
单位长度电感（H/km）— Line inductance
0.9337E-3（默认）|正标量
henries/km（h/km）的电感I每单位长度I。
Capacitance per unit length (F/km)— Line capacitance
12.74e-9（默认）|正标量
电容C/单位长度C，以FARADS/km（f/km）为单位。
Show send and receive ports- 启用端口
离开（默认）|在
Select to show the input and output portsr和s。什么时候selected, theDecoupling Lineblocks can be paired by connecting them with Simulink signals. You connect thes第一个街区的端口r第二个块的端口，然后连接s第二个街区的端口rport of the first block.
内部模型Decoupling Lineblock is directly connected to the externalr和s块端口。
To break the algebraic loop created by this type of connection, you can add a单位延迟block at the output of eachDecoupling Lineblock.
什么时候Show send and receive portsis cleared, theDecoupling Line通过使用配对IDparameter, which transmits the electrical signal information travelling from one terminal to the other by the use of internal Simulink去和从块。一个单位延迟还将块添加到输出信号路径中以打破代数循环。此延迟的示例时间参数对应于在Powerguiblock.
配对ID— Pairing identifier
L001（默认）
当。。。的时候Show send and receive ports清除参数，内部去和从块用于配对两个Decoupling Line模型中的块。在两个块中，配对标识符的第一部分都是相同的，但是您必须附加_sto the end of the identifier of one block, and_r的另一块的标识符。一个n error is produced if the identifier does not end in_s或者_r。例如，假设您添加两个Decoupling Lineblocks to your model. To pair the blocks, you must set the配对IDparameter of one block toL001_S和the other block toL001_R。
初始值
初始电压（V）— Initial voltage
1（默认）|scalar
Initial value of the terminal voltage, in volts.
Initial voltage angle (Deg)- 初始角度
0（默认）|scalar
一个ngle of the initial voltage, in degrees.
初始电流（a）— Initial current
1（默认）|scalar
电流的初始值，以安培的形式流出块。
Initial current angle (Deg)- 初始角度
0（默认）|scalar
一个ngle of the initial current, in degrees.
