Method, device, and system for controlling operation of generator

An apparatus for controlling an operation of a generator set, wherein the generator set comprises at least two circuits for power generation and transmission, the apparatus comprising:

• a detection and determination module, configured to:
• determine whether a preset condition for switching into a partial power operation mode is satisfied, in response to detecting that any one of the at least two circuits for power generation and transmission fails;
• and
• an operation mode control module, configured to:
• control 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 control 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 the partial power operation mode is satisfied, so that the generator set enters the partial power operation mode.
