Abstract
The article provides basic information about the development and mathematical model of static operation modes of an electric drive system, based on an asynchronous valve cascade with sequential engine excitation. The mathematical model allows us to analyze the harmonic series of the drive electric power characteristics. Based on the proposed mathematical model, the features of control modes of the power keys of the stator inverter are considered. The developed mathematical model is the basis for the analysis and prediction of the occurrence of possible emergency modes of the power part of the electric drive and the loss of control of the inverter power keys. The article presents an analysis of electrical and mechanical losses, characterizing the operating mode of the electric drive. Causal dependencies have been identified that make it possible to determine the optimal set of physical quantities, the measurement and control of which allows one or another operating mode of an electromechanical system to be evaluated with the required accuracy.
