Abstract: Spectrum analysis is a fundamental tool for diagnostic purposes widely used in monitoring and diagnostic systems. Estimation of frequencies of multiple sinusoids in the presence of noise arises in many areas of electrical power engineering. The most recent methods of spectrum estimation are based on the linear algebraic concepts of subspaces. Min-norm harmonic retrieval method is an example of eigenstructure-based methods, which yield high resolution and asymptotically exact results. In this paper some results of simulation investigations of inverter-fed induction motor drive are presented. We use the EMTP-ATP program to simulate the PWM converter supplying an asynchronous motor. A measuring system consisting of the data acquisition module SigLab™ and a personal computer was realised and tested.
