Kuznetsov V. The development of the theoretical bases in DC traction power supply systems

The thesis is dedicated to the development of theoretical bases of DC traction power supply systems to increase energy and economic efficiency of the transport. It's created a methodological approache to the selection of energy saving measures in the DC traction power supply systems. It's improved the method for calculating the traction power supply systems based on the restoration flows for estimating the power and energy losses in the elements of traction substations. It's developed the method for determination of rational modes of DC traction power supply systems based on genetic algorithm, defined the rational switching rules. The author developed scientific justified methods for determining norms of electricity needs for stationary consumers and for self needs of traction substations, sectioning posts and points of parallel connection.
