Calc quadrature axis short-circuit transient time constant T'qo

[Guilhermebr]

Hello.

how to calc T'qo (quadrature axis short-circuit transient time constant) with:

𝑇′𝑑0 Direct axis open-circuit transient time constant 𝑠 2.460
𝑇′𝑑 Direct axis short-circuit transient timeconstant 𝑠 0.149
𝑇′′𝑑 Direct axis short-circuit subtransient time-constant 𝑠 0.020
𝑇𝑎 Armature DC-time-constant 𝑠 0.020
𝑇′′𝑞 Quadrature axis short-circuit subtransient time-constant 𝑠 0.032

Since quadrature total magnetic flux does not include excitation magnetic flux, no transient circuit [and no transient time constant] exists. Subtransient time constant exists.
