I have a issue interpreting what transmission line voltage actually means (I have tried researching but nothing clearly explains in detail, just says its a 110kV line etc).For example if i have a 220kV transmission line, and this transmission line is modeled by short line approximation (hence admittance is negligible), is this 220kV what is being received (for VR). I assume not as then the sending end voltage would be higher than 220KV due to line losses hence i am confused to what this 220kV entails.
Instead is this 220KV essentially like the middle voltage of the line? As in the line wants to have voltage that is around 220KV, thus is it just a guide? However the actual sending end voltage could possibly (most likely) be higher than 220KV and the receiving end voltage be lower than 220kV, i.e. constantly varying based upon the load recieved.
Therefore when a question or someone states "thats a 220kV or thats a 110kV line", is that value essentially what the lines voltage will be maintained around, i.e. it could be higher than 220kV or lower than 220kV but it wants to see pretty much 220kV? Like a middle guide basically for the line?
Thanks in Advance
