Abstract:
This article presents a model and research results, developed on the basis of Matlab, that the dynamic characteristics of the output values of a current transducer located on the stator slots at the time of starting asynchronous motors. For control systems and regulation of reactive power of an induction motor, the role is important in research that the dynamic characteristics of the three-phase alternating current of the stator to voltage, these characteristics reflects change and the dependence in time, value of the stator current, parameters of measuring elements, external influences, parameters of an asynchronous motor and other influences that output signals in the form of voltage. The study of the dynamic properties of the signal received from the measuring medium, taking into account the interaction of various characteristic quantities in connection with the difficulties arising in the formation of differential equations of the transducer describing the transition processes in the primary and secondary sections of signal conversion, signal transmission elements, studies are carried out on the basis of a large-scale simulation model and its analytical expressions.
