“…Thuật toán di truyền được Pereira và các cộng sự [7] áp dụng để tìm vị trí tối ưu của các trạm chỉnh lưu trên hệ thống cung cấp điện giao thông một chiều. Với nguyên tắc là phân phối đều phụ tải tiêu thụ cho các trạm điện kéo, các tác giả đã đề xuất hàm mục tiêu là tổng của các sai lệch công suất tiêu thụ lớn nhất giữa các trạm và sai lệch năng lượng tiêu thụ giữa các trạm.…”

Optimal location and capacity of substations play an important role in the railway power system that not only ensures the safety and reliability in operation process but also significantly affects on the total cost of railway power supply system. This paper proposes a new method to solve the problem of optimal substation planning in the urban railway systems. On the basis of a fixed load model converted to the moving load of the train, the proposed method improves the linear programming to find the minimum number of substations and their optimal locations for minimizing the total cost as well as the power loss of the railway power supply system. The simulation on a test system base on the data of Cat Linh -Ha Dong railway system was tested for evaluating the effect of the proposed approach. The simulated results showed that the proposed method is flexible and feasible in solving the substation planning problem for railway electrification systems which can be used as a solution to the pre-planning stage as well as in the detailed design for urban railway systems.

This paper has the main objective, to show the evolution of passenger transport by railway in the metropolitan area of São Paulo (RMSP), with the central point in the capital city, one of the largest cities in the world with over 12 million inhabitants. At first, the Brazilian plan for urban mobility is presented. After, will be discussed the development of railway system in the RMSP and its six lines, focusing the administrative police until the creation of the Paulista Company of Metropolitan Trains (CPTM) and the gradual increase that reached a record of transported passengers: 3,025,185 on December, 2013. Also will be discussed the evolution of built stations as well as the technical characteristics of trains and the improvements through the traction technology. GHG emissions are addressed, making comparisons with others transports. To finalize, the text will be shown future projects of the "Metropolitan Transport Plan" and the conclusions about the service.

This paper is concerned with the possibilities of transformation the DC traction substations with uncontrolled rectifiers into active substation, being able to ensure both the braking energy recovery and active filtering function. There are a lot of approaches on the management of regenerative braking energy, most of them based on energy storage systems or the concept of reversible substation. Few references refer to the addition of complementary functions, such as harmonic filtering, and involve the adoption of specific structures without further argumentation. In this paper, the intention is to analyze and find argumentations on the possibilities of coupling a three-phase active power filter based on voltage source inverter topology in the power structure of a DC traction substation. The most used types of uncontrolled rectifiers, i.e. the three-phase bridge scheme and both 12-pulse parallel and series structures are taken into consideration. Based on correlation between the DCline and AC-line voltages, it is shown that the active power filter can be connected directly in the secondary of the existing traction transformer only in the case of 12-pulse series rectifier. A dedicated recovery transformer is required for the other two schemes of rectifiers and some considerations and results on the compensating power and correlation between the active filtering performance and the voltage in the recovery transformer primary are presented.
