| Abstract: | The UHVAC transmission faults may impact frequency change of Hubei power grid. This paper analyzes the influence of UHVAC lines disconnection on the frequency of Hubei power grid. The frequency stability of Hubei power grid is studied under the three phase short circuit fault of UHVDC system. Considering the frequency adjusted by the HVDC system, the existing frequency regulated methods are adopted to keep the frequency near its rated value after the Hubei power grid occurred the fault. |
