A method for controlling an operation of a generator set, wherein the generator set comprises at least two circuits for power generation and transmission, the method comprising: determining (S201, S302) whether a preset condition for switching into a partial power operation mode is satisfied, in response to detecting that any one circuit for power generation and transmission of the at least two circuits for power generation and transmission fails; controlling (S202, S303) at least one circuit for power generation and transmission without a fault among the at least two circuits for power generation and transmission to enter an operation mode, and controlling a circuit for power generation and transmission with a fault to enter a shutdown state, in response to determining that the preset condition for switching into the partial power operation mode is satisfied, so that the generator set enters the partial power operation mode, and characterized by adjusting a rotating speed of a sub group of converters in the any one circuit for power generation and transmission without a fault and being controlled to enter into the operation mode, in a case that the any one circuit for power generation and transmission without a fault and being controlled to enter into the operation mode has reached a specified output power, wherein determining whether the preset condition for switching into the partial power operation mode is satisfied comprises: determining whether the at least one circuit for power generation and transmission without a fault satisfies a condition for operating in the partial power operation mode, based on state information fed back from a converter in each circuit for power generation and transmission; showing a prompt message indicating that the at least one circuit for power generation and transmission without a fault satisfies the condition for operating in the partial power operation mode, in response to determining that the at least one circuit for power generation and transmission without a fault satisfies the condition for operating in the partial power operation mode; and determining that the condition for switching into the partial power operation mode is satisfied, in a case that a manual reset command in response to the prompt message is received within a specified time period. determining (S201, S302) whether a preset condition for switching into a partial power operation mode is satisfied, in response to detecting that any one circuit for power generation and transmission of the at least two circuits for power generation and transmission fails;
