Abstract

The authors of the article describe and analyze the processes of functioning of a synchronous electric motor-generator (EDG). A review of mathematical descriptions of synchronous EDG is presented. A simplified mathematical description is proposed that makes it possible to simulate the process of functioning of the hybrid propulsion system (GSU) in typical modes of movement of wheeled vehicles (CTS). The functional dependences of the current, power and torque on the rotor speed of the synchronous EDG of the Toyota Prius car are presented.
 The goal is to develop a simplified mathematical description of a synchronous electric motor–generator of a car with a hybrid power plant.
 The method or methodology of the work is a numerical method based on the finite – difference scheme of the Park method, using a special numerical-iterative method of composing equations of motion.
 Results – a simplified mathematical description has been developed, which allows to determine the functional dependencies necessary for the analysis of the functioning of the CCC with GSU.
 The scope of the results. It is advisable to apply the results obtained when modeling the processes of functioning of a synchronous electric motor-generator of a hybrid power plant of wheeled vehicles.
