ACCOUNTING OF THE VOLTAGE CHANGE FACTOR ON THE PANTOGRAPH OF THE DIRECT CURRENT ELECTRIC STOCK WHEN CARRYING OUT TRACTION CALCULATIONS
Accuracy increase in traction calculations allows increasing reliability of rationing and forecasting electric energy consumption for haulage of trains. Voltage across pantograph of electric stock fluctuates over a wide range. This circumstance is considered when carrying out traction calculations in special cases of the undervoltage in a contact line. The paper proves that accounting of voltage change received by results of iterative electric calculation of direct current power supply traction system allows increasing the accuracy of traction loading calculations and electric energy consumption on haulage.
