In the paper multiterminal voltage source converter based HVDC (VSC-HVDC) is proposed to interconnect wind farms to AC grids. The method highlights the control at the level of wind generator cluster that comprises several permanent magnet synchronous generators without the primary converters on themselves. For the cluster control, active and reactive power decoupling scheme is applied to adjust the...
The paper presents the dynamic model and control schemes of a variable speed pitch wind turbine with permanent magnet synchronous generator (PMSG). The model includes a PMSG model, a pitch-angled controlled wind turbine model and a drive train model. The drive train model uses one-mass model to represent the mechanical characteristics of the generator set. The generator model is established in the...
With increasing attention to sustainable development and environmental protection, more and more countries turn to wind energy to reduce their dependence on traditional fossil fuel energy. Among the new challenges with this trend is how to integrate wind farm with existing AC network more effectively. The paper presents a possible measure based on VSC-HVDC, namely so-called wind farm incorporated...
