The invention discloses a hybrid phase shift control strategy applicable to LCC DC power transmission system inverter side AC fault. The strategy includes phase shift control which is based on rate of rise and transient value of a DC current and phase shift control which is based on mean square root and degree of asymmetry of an AC voltage. The phase shift control which is based on rate of rise and transient value of a DC current is intended for initial action of an inverter side AC fault so as to circumvent failure of phase shift or shorten the time length of the failure of phase shift if phase shift fails. The phase shift control which is based on mean square root and degree of asymmetry of an AC voltage is intended for system recovery action in the middle and later stage of an inverter AC fault and when the fault is resolved in order to optimize system recovery features. Therefore, the strategy herein can effectively address the failure of phase shift caused by inverter side AC fault of the system.
