Determining capacity of end line reactor
Determining capacity of end line reactor
(OP)
Dear friends
I have a 400-kV transmission line for a simulation which conductor type and tower configuration specified and compenseted through a end line reactor. how to determine a nominal capacity for the corresponding reactor in order to reduce switching overvoltage surges? The end line is opened without any load.
Regards

I don't believe it will reduce the switching surge transient overvoltages or at least not in a significant way.

Can you elaborate on what you mean my free and forced components?

RE: Determining capacity of end line reactor
I know about free and forced component, but my questions is following:
1- how to determine a nominal capacity for the EHV shunt reactor, while the line's load not assigned and my EHV line only recognized through conductor type and tower configuration?
2- how to determine capacity for the line by conductor type and tower configuration without load characteristics?
Thank you again!

For some radial EHV lines, we use different schemes based on the system requirements. we apply different sizes other than 40% 40%. it depends on the network you have and line parameters, SLG operation for neutral reactor requirements, reactive Var control via the lines, normal operation voltage control ,generator stability, power frequency O/V control , switching transient concerns and others. I knew in a sub we put in a small EHV reactor only to accommdate the neutral reactor and SLG operation.
