METHOD FOR INCREASING ENERGY INDICATORS OF REGENERATIVE BRAKING OF AC ELECTRIC CARS

摘要

A method for increasing the energy performance of single-phase-direct current electric locomotives in the regenerative braking mode, including the supply of control pulses to the inverter arms by a control unit of a rectifier-inverter converter or a microprocessor-based motion control and diagnostics system, and in the high-speed zone of movement on the fourth voltage regulation zone on generators the angle of regulation αр is limited at the level of 3.5 zones, which determines the constant transformation ratio of the transformer, characterized in that in the zone of high speeds of movement of the electric locomotive, change the transformation ratio of the transformer when regulating the regenerative current by increasing the voltage to the maximum permissible level of traction motors operating in the mode generator, taking into account the reduction of the voltage drop across the blocks of ballast resistors by means of a functional regulator, which is an electronics board installed in the control unit ...
