抄録

In order to develop the train operation control algorithm for a group of trains, it is necessary to evaluate the energy efficiency and the operational robustness by simulations. Especially, energy efficient operation of a group of trains is so attracted as well as of each train. In this paper, a flow of the train traffic simulator and delay occurrence for operational robustness are stated briefly, and methods of modeling and calculation of a feeding circuit are stated in details, which are important technical elements to evaluate the energy efficiency in the train traffic simulation. The feature of our feeding circuit model is introduction of the "tie nodes" and the "tie matrix", which show that some nodes are in the same voltage. Introduction of them improves the pliability of the modeling and calculation according to change of feeding network composition. Applying the proposed model and calculation method in C++, the converged results were acquired in three test cases using the general-purpose calculation solver. The computation time and the calculation error are sufficiently less, even compared to the referential results by MATLAB. We are to verify accuracy of our model using field data and use it for development of train operation control algorithms.
