Mathematical model of an electrical complex with the device of electrical energy storage for testing induction motors

Abstract

The research highlights the problem of developing repair infrastructure for new rolling stock, including those with asynchronous traction motors. Therefore, an electrical engineering complex for testing asynchronous motors was chosen as the object of research. The scheme of testing a pair of asynchronous machines using the method of mutual loading is considered. To smooth out current surges in transient modes, an electric energy storage device is used in this scheme. As a result of the research, a mathematical model of the test circuit in question was obtained, which considered an energy storage device connected to a DC link of the test circuit. The solution of the test problem to verify the operability of the considered circuit showed its high efficiency in smoothing current surges in transient modes in the mutual load circuit.
