Project: 1000 MW VSC Monopole in Europe
Service: VSC HVDC
Year: 2013 — 2014
TGS performed technology and grid studies using PSCAD and PSSE for a 1000 MW monopole point-to-point VSC link, which uses underground 320 kV XLPE cables for DC transmission. The project involved the evaluation of both technical and grid requirements.
There were some unique grid code requirements that the VSC had to comply with. Special control features were needed in order to meet the grid code requirements. The project involved the full range of studies including technology studies to identify limitations and challenges, transient stability, SSR mitigation and harmonic and control interaction studies.
