摘要:
ATP-EMTP simulations of a 3-phase commercial
power distribution system containing adjustable speed drive
(ASD) driven induction motors in the presence of voltage sags are
described. The simulations show both the dynamic influence of
the motor on the temporal evolution of certain sags, and the
absolute ASD de link voltage and peak current as a function of
fault type, location, and duration. The results show that dc link
recovery currents can be several times larger than their nominal
values, and that the most severe absolute effect occurs during
and after a long (1000 msec) three phase fault at an electrically
remote location
