摘　　要：特高压故障开断后有可能对湖北电网的频率造成冲击。为分析特高压开断对湖北电网频率的影响,研究了特高压线路开断后对湖北电网频率的影响,并考虑直流系统参与频率调整,通过现有的调频手段将故障后湖北电网频率稳定于额定值附近。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 shorvcircuit 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.
