dilo Converter Station system

Resonance and harmonic phenomena can occur when HVDC and Flexible Alternating Current Transmission System devices are inserted into ac grids. Frequency response analysis and electromagnetic transient (EMT) type simulations of converter stations are essential for analyzing and preventing negative effects. This paper presents two approaches for deriving the high frequency response of a converter ...

    Converter is the heart of the HVDC system and performs AC/DC and DC/AC conversion. Each HVDC system has two converters one at each end. The converter at transmitting end act as a rectifier and the converter at the receiving end act as an inverter. Based on the HVDC technology the converter can be based on IGBT or Thyristor switching elements.
