Models of quasi-static DC machines
This package contains quasi-static models of DC machines; these models are fully compatible with the transient machine models of DC machines; the only difference is that electrical transients are neglected.
Quasi-static DC machine models are basically different from quasi-static induction machine models:
Quasi-static DC machine models neglect electrical transients, i.e., setting der(i) = 0
,
whereas quasi-static induction machine models are based on time phasor theory,
see QuasiStatic Library,
where e.g., L*der(i)
is replaced by j*omega*L*(I_re+j*I_im)
.
