HVDC Transmission Link Software

VSC-HVDC Transmission System Modeling

Model and Simulate High Voltage Direct Current (HVDC) Transmission using Voltage Source Converter technology for power grids and offshore wind parks.

ETAP VSC-HVDC Transmission is used to simulate and analyze the transmission of AC and DC electrical power flow across the grid using unified power flow.

HVDC Link

ETAP includes VSC-HVDC modeling in addition to the line commutated converter technology for Power Flow, Fault Analysis, Harmonics, Dynamic Stability analyses and more. ETAP HVDC simulation utilizes unified power flow where AC and DC network is solved simultaneously (not iterative AC/DC or sequential solution) allowing for faster convergence and precise snapshot or time series solution.

ETAP VSC-HVDC transmission link includes vendor specific control schemes and dynamic modes of operation. ETAP HVDC transmission link model includes HVDC station (rectification and inversion), DC grid and AC/DC coupling on either side of the converters.
