Research on Stability Control Strategy for Island System of HVDC

摘要

With the rapid development of HVDC technology and the commissioning of the HVDC project in recent years, the HVDC control strategy has also been fully developed; As the particularity of the point-to-net HVDC, the control strategy of weak system at AC sending end HVDC has become a new challenge. On the basis of analyzing the status of HVDC project in this paper, by classifying the weak sending end HVDC project and making comparisons, this paper summarizes the current control strategy of weak sending end HVDC and analyses the control strategy of the thermal power units sending end and hydropower units sending end. In the end, this paper puts forward that the control strategy of weak sending end HVDC will be the key of the research in the future.
