Mass Rapid Transit(MRT) plays a very important role for the city development,the investment cost is very expensive. It is necessary to derive the MRT system planning by considering the service reliability and performance index according to the forecast of annual ridership. With the less ridership as compared to Taipei MRT network, Kaohsiung MRT has to be developed to achieve the most cost effective investment of power supply and rolling stock planning. This thesis is to investigate the proper expansion planning of traction substations (TSS) for an electrified mass rapid transit system. The motion equation of train sets is used to solve the mechanical power consumption at each time snapshot according to the operation timetable, the passenger ridership and various types of operation resistance. The mathematical models of power converters in traction substations for different operation modes have been derived. With all train sets operated along the main line, the AC/DC load flow analysis is performed to find power demand of all traction substations for annual system peak operation over the study period. The objective function is formulated by considering both the voltage drop of train sets and investment cost of traction substations as the equivalent cost of all feasible states of each year. By performing the dynamic programming (DP) and immune algorithm (IA), the expansion planning of traction substations to achieve the minimum overall cost has been solved by identifying the optimal capacity and locations of new traction substations to be committed at each year.

Esta dissertação apresenta uma proposta de integração sistêmica da automação das subestações retificadoras do sistema metrô-ferroviário brasileiro. Esta dissertação também apresenta os ganhos de confiabilidade que podem ser obtidos, caso a mesma seja implementada, e a priorização da eficiência de operação do sistema em questão. A motivação deste trabalho deve-se à necessidade de atender à perspectiva de aumento de demanda de energia elétrica nos processos de expansão e modernização deste sistema, amplamente usado pela população brasileira. A partir do estudo e análise do atual sistema de automação existente nas subestações do sistema metrô-ferroviário brasileiro, da arquitetura de hardware e software, foi possível investigar como a integração dos dados pertencentes aos sistemas de controle da subestação e do Centro de Controle Operacional CCO - pode permitir o aumento da confiabilidade e da flexibilidade de operação. Para quantificar estes ganhos de confiabilidade é apresentado o desenvolvimento do modelo de confiabilidade de Markov aplicado ao sistema de automação de subestações retificadoras. A metodologia utilizada procedeu ao levantamento e análise das ocorrências abertas nos anos de 2006, 2007 e 2008 nas subestações retificadoras do metrô de São Paulo, calculando o seu MTBF (Mean Time Between Failures). O estudo conclui que o ganho de confiabilidade é significativo no que se refere à melhoria do transporte público com a aplicação da integração da automação das subestações retificadoras. / This dissertation there presents a proposal for the integrated automation of the Brazilian subway system rectifier substations, supported on the gains of reliability which may be obtained in case it is implemented, and in the improvement of the efficiency of operation of the system open to question. The inquiry was supporting in the necessity of paying attention to the perspective of increase of demand of electric energy in the processes of expansion and modernization of this system, widely used by the Brazilian population. From the study and analysis of the current system of existent automation in the substations of the system Brazilian subway, of the architecture of hardware and software, was possible to investigate like the integration of the pertaining data to the systems of control of the substation and of the Centre of Operational Control CCO can allow the increase of the reliability and of the flexibility of operation. To quantify these profits of reliability there is presented the development of the model of reliability of Markov devoted to the system of automation of rectifying substations.

In this thesis, the lightning surge characteristics of the facilities in electric railway systems were measured. The characteristic of earthing impedance was also investigated from the viewpoint of lightning surge. In addition, some numerical models of railway specific apparatuses for circuit analysis method were developed by applying simulation technology for power system and confirmed their accuracies by actual measurements. The responses to lightning currents invaded into the facilities were clarified by the measured and calculated results. These results can be fully utilized in the design, maintenance and analysis of electric railway systems. / 博士(工学) / Doctor of Philosophy in Engineering / 同志社大学 / Doshisha University
