Abstract

The authors offer the procedure of calculation and development of mechanical characteristics of a frequency-regulated induction drive using a standard MATLAB program. Using the basis equivalent circuit of induction motor and per unit equations the authors developed the scripts of the static mechanical characteristics, which are a convenient tool of automation and visualization of the process of designing of electric drive which consists of the motor, the transformer and the transistor converter. The article gives the examples of scripts and the diagrams of mechanical characteristics for various frequency control scalar laws. It is revealed, that research of mechanical characteristics using the developed scripts allows to study the interrelations between parameters of the induction drive, kinds and parameters of frequency regulation, and also to observe the frontier of the induction motor working at certain values of supply voltage and frequency. The article shows that the development of mechanical characteristics using ready scripts allows to estimate quickly the static parameters of speed control quality under various control laws and compare the received results to parameters of the load mechanism. Besides, the authors noted that, using the received diagrams, it is possible to check promptly the conditions of realization of frequency regulation with IR-compensation, and to do without time loss the conclusions about the acceptability of u/f control for a designed drive or the necessity of vector regulation choice. Thus, offered technique of mechanical characteristics development based on the scripts application promotes the improvement of research visibility, and the optimal conditions development for the analysis of static operating modes and the selection of a type of control of the designed frequency-regulated induction drive.
