DEVELOPMENT OF A LABORATORY SYSTEM FOR RESEARCH OF MOTOR-GENERATOR GROUPS

Vasil Dimitrov, Petko Kostadinov

In accordance with the rapid technological development and the implementation of power electronics in traction and auxiliary drives in electric vehicles and automobiles, it is increasingly necessary to continuously increase the energy efficiency of drive mechanisms and power generation systems. Therefore, it is especially necessary not only theoretical training of specialists involved in the design, manufacture and setting up of control systems for electrical drives, but also enhanced practical orientation in education, in line with trends in the development of contemporary technologies. Ensuring optimal operating modes and maximum energy efficiency of synchronous generators and induction motors depends to a large extent on a good knowledge of their characteristics.

In this regard, the paper presents the development of a laboratory stand for studying the various characteristics of synchronous and asynchronous machines, which should be used for conducting laboratory exercises, research and experiments and have to provide the following opportunities:

- study of the characteristics of a synchronous generator at change of excitation and at different load.

- study of the characteristics of an alternator at change of excitation and at different load.

- study of the characteristics of a frequency controlled asynchronous drive.

- study of the characteristics of a synchronous motor.
