Abstract
West Japan Railway Company has been developing technologies for effective use of the regenerated energy in order to reduce power consumption (Energy storage system, Power conversion device, etc).These developments effect of reducing the power consumption has been confirmed. However, the effect did not necessarily accord with the expected values. To estimate the effect is to model the electrical circuit from the substation, the simulation for sequentially calculating the power consumption of the vehicle based on the operating diagram and driving operation is enabled. we reveal the impact on the power consumption by the vehicle performance and driving operation and the power supply path, is working on the development of the simulator integrated that reflects the computational model of each field. In developing, in order to grasp the electrical reality, we performed a simultaneous measurement of the power consumption in vehicles and the substations. From the results, the total current of substations and the current of a vehicle were roughly match, examination circuit is properly configured. Furthermore, in 2014 to rectify the accuracy problems of the voltage sensor and the examination was carried out again. In addition, we also performed examination in another line section where conditions are different, the acquired basic data of the simulator development.
