Abstract |
Recently, various studies are being conducted to establish an eco-friendly energy network in the field of railway transportation to reduce carbon emissions. In particular, if the regenerative energy generated from DC urban railway trains, which is frequently reversed and braked, is used appropriately, railroad operating costs can be reduced, which is economical. In this paper, considering the voltage stabilization aspect and the energy utilization aspect through load flow analysis, an appropriate regenerative energy utilization facility installation method was analyzed. This section introduces the regenerative energy facility design method using the Minimum Elimination Method(MEM) by performing load flow analysis for each substation through TPS(Train Performance Simulation)-based power system analysis. By using MEM, the regenerative energy utilization rate was improved by about 11.9% compared to the existing method. |
