- Abstract
In order to develop railway freight towards high speed and heavy load, it is necessary to install power generators on wagons to equip them with corresponding safety inspection systems. As a kind of highly cost-effective generator with a simple structure and adaptability to various harsh environments, doubly salient generators are very suitable for power supply of railway wagons. The power demand in railway freight is analyzed, the main performance requirements on the doubly salient generator are determined based on the power demand, the key parameters of the generator are designed according to the formula method and empirical method, and then software ANSYS Maxwell is used for modeling and simulation analysis of the generator to analyze the key parameters such as distribution of the magnetic lines of the generator and three-phase induced electromotive force. Finally, Maxwell and Simplorer are used for cosimulation to analyze the output voltage of the generator after connecting the rectifier circuit and the excitation current required to reach the rated output voltage at different rotational speeds, which provides a data basis for the subsequent design of the constant voltage control system of the doubly salient generator. The simulation results show that the designed doubly salient generator can meet the power demand of the wagon during operation.
