The presented paper deals with the associated problems that come up with common installation of filter and compensation unit with decompensation reactor used in traction power supply system. The influence of single-phase traction converter on the traction trolley and load is a specific problem. The locomotives on the line are a source of harmonic currents. This source affects the voltage distortion on the system. Connection of filtration compensation unit significantly sinks the voltage curve distortion, especially at the power supply station. Due to compensation power of filters is necessary present decompensation reactor. This paper describes the steady states and is focused on the possible extreme cases. The influence of filter parameters in cases of extreme distortion has been investigated.

In high-power traction applications, low distortion power factor (DPF) is generally desirable under all conditions because although the higher harmonic currents cannot apply active power to loads, they cause higher losses in the transmission line and can disturb track circuits. Operation of single-phase current-source active rectifier (ACSR) under distorted catenary voltage conditions causes distortion of catenary current in terms of high THDi values which from the above reason should be suppressed. In this paper, three approaches in DPF control will be introduced, compared and evaluated from the quality of compensation, stability of operation and complexity point of view. Theoretical expectations of considered compensative strategies and their behavior have been verified by both simulations and large experimental study made on developed small-scale prototype of ACSR of rated power of 7kV A.

In traction applications, critical transient conditions such as trolley bounces, voltage dips or fast power variations can occur. This paper investigates a behavior of single-phase active current source rectifier (ACSR) under above stated critical transient conditions. The analyzed ACSR was controlled by a strategy able to control Power Factor (PF) as well as Distortion Power Factor (DPF) with active harmonic mitigation approach based on resonant controllers. Proper function of proposed control strategy and its behavior under critical transient states have been verified by both simulations and large experimental study made on developed small-scale prototype of ACSR of rated power of 7kVA.
