Railway traction has become an important part of power system. It creates power quality issues in the grid. Negative sequence and harmonic currents have become the main issues in high speed train traction systems. Railway static power conditioner (RPC) has been developed to mitigate the power quality issues. A comprehensive technique for compensation of negative sequence and harmonic currents has...
ldquoHarmonic transfer through convertersrdquo has caused waveform distortion in multiterminal dc systems based on a voltage-source converter (VSC-MTDC). The harmonic transfer can be by the positive and negative sequences or by the zero sequence. A comprehensive solution consists of decoupling the ac side from the dc side of the VSC. Such decoupling has other benefits in VSC-MTDC because disturbances...
