直流き電システムのシミュレーション手法における運転時分の一定化および反復収束計算法の改善 The Method to Keep Train Operation Time Constant and Improvements of the Repeated Convergence Computation of the Simulation Program for the DC Feeding System
The simulation program is an extremely powerful tool to examine the substation capacity, pantograph voltage and effects of improving electric facilities of the DC feeding system, which should further be improved to be easier to use at higher precision and also to cut computing time.<br>We improved the program, therefore, to make it possible to keep the train operation time constant by computing run curve data for this purpose in advance. To do this, we also control traction currents to suppress changes in train speed due to fluctuation of pantograph voltage. To Simulate train operation more closely to actual situations, we improved the program to enable simulation in optional time zones.<br>In addition, we clarified the theory of repeated convergence computation, improved the methods of averaging and judging computation results, and expedited the computation to attain earlier convergence.
