The invention relates to a modeling method with adaptive
voltage disturbance resistance. Prevention and protection for the problems that due to
voltage disturbance, a
contactor trips, and a frequency converter and a soft
starter halt are effectively achieved. The method includes the steps that input
signal data is adjusted through an
adaptive filter to form dynamic parameters, a non-
adaptive filter has a static filter coefficient, the dynamic parameters and the static filter coefficient form a
transfer function, and an adaptive
database is formed; the filter coefficient and the
frequency response are adjusted through the
adaptive filter, the change characteristics, periodic characteristics and change amplitude characteristics of the data are analyzed, a preliminary mathematic model is established, and piecewise function
processing is carried out;
adaptive software adapting to the power distribution network electrical aspect and the mechanical aspect is obtained according to a
software control program to meet actual on-site operating requirements; operating parameters of the electrical aspect and the mechanical aspect are constantly collected, and adaptive iteration is carried out to approach the optimal solution. By means of the method, it is guaranteed that equipment on a
production line can operate without halting, and the continuity of production can be kept.
