  2. Transmission line - Wikipedia

    en.wikipedia.org/wiki/Transmission_line

    The resistance and conductance contribute to the loss in a transmission line. The total loss of power in a transmission line is often specified in decibels per metre (dB/m), and usually depends on the frequency of the signal. The manufacturer often supplies a chart showing the loss in dB/m at a range of frequencies.

  3. Power system simulation - Wikipedia

    en.wikipedia.org/wiki/Power_system_simulation

    Using network topology, transmission line parameters, transformer parameters, generator location and limits, and load location and compensation, the load-flow calculation can provide voltage magnitudes and angles for all nodes and loading of network components, such as cables and transformers.

  4. Load-loss factor - Wikipedia

    en.wikipedia.org/wiki/Load-loss_factor

    Multiple empirical formulae exist that relate the loss factor to the load factor (Dickert et al. in 2009 listed nine [5]). Similarly, the ratio between the average and the peak current is called form coefficient k [ 6 ] or peak responsibility factor k , [ 7 ] its typical value is between 0.2 to 0.8 for distribution networks and 0.8 to 0.95 for ...

  5. Performance and modelling of AC transmission - Wikipedia

    en.wikipedia.org/wiki/Performance_and_modelling...

    The AC transmission line is used for transmitting the bulk of the power generation end to the consumer end. [5] The power is generated in the generating station. The transmission line transmits the power from generation to the consumer end. High-voltage power transmission allows for lesser resistive losses over long distances in the wiring. [5]

  6. Impedance matching - Wikipedia

    en.wikipedia.org/wiki/Impedance_matching

    If the source impedance matches the line, reflections from the load end will be absorbed at the source end. If the transmission line is not matched at both ends reflections from the load will be re-reflected at the source and re-re-reflected at the load end ad infinitum, losing energy on each transit of the transmission line. This can cause a ...

  7. Electric power transmission - Wikipedia

    en.wikipedia.org/wiki/Electric_power_transmission

    "Black box" model for transmission line. The terminal characteristics of the transmission line are the voltage and current at the sending (S) and receiving (R) ends. The transmission line can be modeled as a black box and a 2 by 2 transmission matrix is used to model its behavior, as follows:

  8. Mismatch loss - Wikipedia

    en.wikipedia.org/wiki/Mismatch_loss

    Mismatch loss in transmission line theory is the amount of power expressed in decibels that will not be available on the output due to impedance mismatches and signal reflections. A transmission line that is properly terminated, that is, terminated with the same impedance as that of the characteristic impedance of the transmission line, will ...

  9. Telegrapher's equations - Wikipedia

    en.wikipedia.org/wiki/Telegrapher's_equations

    Equivalent circuit of an unbalanced transmission line (such as coaxial cable) where: 2/Z o is the trans-admittance of VCCS (Voltage Controlled Current Source), x is the length of transmission line, Z(s) ≡ Z o (s) is the characteristic impedance, T(s) is the propagation function, γ(s) is the propagation "constant", s ≡ j ω, and j 2 ≡ −1.
