An automatic procedure to identify on-line the induction machine parameters of the steady-state equivalent circuit is presented.

Different methods identify the parameters of the equivalent circuit, starting from the available sets of variables.

Abstract

An automatic procedure to identify on-line the induction machine parameters of the steady-state equivalent circuit is presented. The procedure starts with the acquisition of input current and voltage instantaneous values and their process to obtain the following dataset of variables: current and voltage first harmonic values, their displacement and the slip value. The slip value is obtained through the current spectrum lines due to the rotor slotting. This first step is automatically iterated if the operating condition changes, to obtain more sets of variables. Different methods identify the parameters of the equivalent circuit, starting from the available sets of variables. All the process, configured as a virtual instrument, is implemented in LabVIEW environment and can be included in a diagnostic system to detect machine healthy conditions, in order to expand system capabilities.
