Abstract
A novel proportional resonant (PR) control strategy in the VSC-HVDC system for offshore wind farms is proposed in the paper. The technique took full advantage of the characteristics of PR controller, which can realize zero steady-state error of AC input signal in the stationary frame. In the method,by using the vector control strategy, the active and reactive current component were transformed into the stationary frame to achieve the target of keeping the DC-link voltage constant,and decoupling the active and reactive power. Compared with the common double close-loop proportional integral controller,the PR technique is better in harmonic compensation without the complex coordinate transformation, the decoupling and the feedforward control. Also the control algorithm is easy to be realized while the robustness and power quality is improved. It provides an optimized control scheme in the VSC-HVDC system for offshore wind farms.关键词
