The problems in the loadflow study of the fixed voltage DC traction power supply system including the regeneration power is analyzed. And the computer algorithm to avoid the problem is developed. A computer program using the developed algorithm was developed. A test run of the computer program is conducted and the result shows the algorithm and the program developed is very effective for the loadflow study of the system including the regeneration power.

Block system has been used to protect trains from occupying the same section of track at the same time so that only one train is permitted in each block at a time. Domestic driving regulations on the block system is divided into two classifications, such as regular block and substitute block. If it is impossible to use this regulation, the block applied method can be applied. However, domestic urban railway administrator has established his own operation rule within the regulation. Therefore, in order to assure continuous safety of train in operation, it is necessary to strengthen the regulation as can cope with the various block systems. In this study, domestic urban railway administration's own rules are examined and the appropriate driving regulation on the block system is proposed.
