Abstract
The paper is devoted to the simulation of the test complex designed for energy-efficient load testing of induction machines by the method of mutual load with the exchange of electrical energy through the network. It is noted that for other similar test schemes, the mathematical model will have a slightly different form, but it will be identical in terms of asynchronous machines, network and frequency converter. The compiled mathematical model of the test complex allows studying the variable parameters of the system in all elements of the test scheme in static and dynamic modes of operation as well. The synthesized mathematical model can be used to determine the parameters of the equipment in the designed test complexes if the parameters of the test and load machines are known. The results of simulation of the test complex for the given parameters of the test and load induction machines are obtained.
Highlights
Nowadays, one of the priority areas for the development of industries related to electromechanical energy converters is the introduction of asynchronous converters in exchange for DC machines
Studies [10, 11] consider a mathematical model of physical processes in the interaction of two induction machines, one of which operates in the motor mode and the other in the generator mode
To form a more complete mathematical model, we introduce the notation in accordance with the diagram given in fig
Summary
One of the priority areas for the development of industries related to electromechanical energy converters is the introduction of asynchronous converters in exchange for DC machines. This direction of technology development is supported both at the state and industry level and involves expanding the scope of use of induction machines and introducing innovation systems for their diagnosis and monitoring. For the implementation of this energy-efficient test method, a number of schemes [6,7,8,9] have been developed that make it possible to create a complex for load testing of asynchronous motors
