Fault analysis -- Simplifying to Thevenin equivalent

Click For Summary

Discussion Overview

The discussion revolves around the process of simplifying a circuit to its Thevenin equivalent, specifically focusing on the persistence of a voltage source value after multiple source transformations. Participants explore the implications of these transformations in the context of per unit values.

Discussion Character

  • Homework-related
  • Technical explanation

Main Points Raised

  • One participant questions why the voltage source remains at 1 after several transformations, suggesting a need for clarification on the transformations' effects.
  • Another participant asserts that each transformation maintains equivalence to the original circuit, implying that the final result should reflect this equivalence.
  • A third participant shares a specific numerical result of V=-17.146 with zero angle, indicating an attempt to solve the problem directly.
  • A follow-up request for the working steps of the calculation is made, indicating a desire for transparency in the problem-solving process.

Areas of Agreement / Disagreement

The discussion shows a lack of consensus on the implications of the transformations, with some participants focusing on the theoretical aspects of equivalence while others present specific numerical results. The overall resolution of the question remains unresolved.

Contextual Notes

Participants have not provided detailed assumptions or definitions regarding the transformations or the context of the per unit system, which may affect the clarity of the discussion.

All voltages and impedances are in per unit values.
After all the source transformations, why is the voltage source still 1 ?

Each transformation produces something that is equivalent to what existed before the transformation. So after any number of transformations, including some that reverse previous transformations, it is inevitable that you must end up with something still equivalent to the very first arrangement.
 
I actually tried solving it and I got V=-17.146 with zero angle
