The energy relations in a traction ac power supply system including a power multifunctional booster transformer with a nonsinusoidal current and voltage at the current collector of electric rolling stock are considered. The expediency of the selection and regulation of the compensating unit connected to the compensating winding of the transformer based on the minimum exchange energy determined by the presence of the capacity and inductive energy storages is shown. Generating the reactive energy, the booster transformer reduces the voltage losses in the power supply system due to decreasing the primary current. In addition, due to the effects of the bootstrap and series capacity, it exceeds the voltage in the traction network and, therefore, increases the voltage at the current collector of the electric rolling stock. The proposed coefficient of efficiency of the compensating unit allows selecting its capacity with a sufficient accuracy to ensure the optimal operation mode of the traction power supply system, which is on average 15–20% less than the capacity determined using the existing method.
