Impact Evaluation of HVDC System Control on Short-term Voltage Recovery Characteristics of Receiving-end Grid

With the construction of UHVDC project, the dynamic reactive power source mainly composed of thermal power units in the load center of power grid is gradually decreasing, which poses a serious threat to the short-term voltage security of the receiving-end power grid. Considering the high-capacity transmission and fast response performance of HVDC system during fault, it is beneficial to solve the ...
