Electromagnetic Transient study of wind farms connected by HVDC (SWPTC Etapp 2, TG1-21)
Research Project, 2015
– 2017
An increasing amount of remote large-scale offshore wind farms are being connected to the main onshore grid by means of High-voltage Direct Current (HVDC) systems. The remote sites enable good wind conditions and generation out-of-sight. However, the complex interaction between the interfaces of the wind turbine generators and in particular their converter controls, the cable systems, the offshore substation components and offshore HVDC converter can give rise to resonance phenomena as well as in-proper control or protection actions. The aim of this project is to acquire a deep knowledge on the robustness of this kind of systems and to understand the root causes of possible instability issues through analytical investigations and development of relevant simulation models and guiding principles. In addition, the potential impact of the interactions that might appear in the offshore system on the connecting onshore AC grid will be investigated.
