Description

technical field [0001] The invention relates to the technical field of power supply systems, in particular to a method and system for calculating power supply parameters of rail transit under the condition of non-uniform rail insulation. Background technique [0002] At present, the DC traction power supply system of urban rail transit generally uses the running rail as the return path of the traction current, and the system adopts the suspension grounding method. In the process of urban rail transit design, construction, and operation, the calculation of system power supply parameters is particularly important. By calculating the voltage and current parameters of each node of the line, it can provide a basis for the selection of line design schemes and provide support for line operation status analysis. When the power system adopts DC power supply, a special return line is generally set up, and the insulation level is the same as that of the power supply line. The establish...
