    Influence of settings power reservation systems of dc traction substations to losses of electricity

    The article discusses the issue of improving the efficiency of converting units of DC traction substations. An algorithm for calculating electricity losses in converting units is given by the system-fixed effective values of the phase voltage of the primary winding of the transformer and the load current of each converter unit. Using the example of a conventional traction substation, an assessment of the influence of the operation settings of the regime automation of converting units on the loss of electrical energy is given.
