摘要

Energy saving and emission reduction are gradually receiving more and more attention, the railway system is an important part of the national economy, so the energy saving of it becomes a hotspot. In this paper, the main purpose is to give some feasible schemes to make the economy of electric system of the modern high speed railway much better, a segment of Hefei-Wuhan railway line is chosen as a research sample. With simulation based on PSCAD/EMTDC platform, some irrationalities in the electric design of the high speed electrified railway which will lead to much electric energy waste and affect the economic and social benefits of enterprise are found, such as irrationalities in the selecting of the transformers and the reactive power saving, and the reasons are analyzed. Then, optimize proposals are proposed with the knowledge such as smart grid and the FACTS technology, which contribute practical and heuristic significance to improve the economy of railway line.
