A new educational set-up for a power engineering laboratory

This paper presents a new educational set-up for using in industrial electronics and power engineering laboratory. The presented system consists of a precision power meter, an autonomous data logging unit as well as of application software. It helps students to understand the concepts of power electronic appliances, machines and drives by measuring the typical signals with different filtering and synchronisation tools, visualising the data and investigating the results with analytical models created with Matlab/spl reg/ and Simulink/spl reg/. The educational kit can present typical waveforms, phasor diagrams, real, active and reactive power and spectral diagrams and can also be used for improved laboratory practice, like investigation of transformers, PWM devices and rotating machines. Additionally there is a possibility to evaluate power quality with statistical and regression analysis.
