a hydraulic pump serving as a hydraulic power source of a hydraulic actuator, the hydraulic pump being driven by the engine;
a generator driven by the engine;
an electric storage device that is charged with electric power generated by the generator;
a rotation motor serving as a driving source of a rotating structure, the rotation motor being driven by the generator and the electric storage device;
electric-storage-device breakdown detecting means for detecting that the electric storage device is unusable; and
control means for controlling the generator and the rotation motor, wherein, when it is detected by the electric-storage-device breakdown detecting means that the electric storage device is unusable, the control means is configured to perform emergency evacuation control that suppresses the power consumption of the rotation motor to be less than or equal to the power generation of the generator while maintaining voltage of a direct current bus greater than or equal to a normal operation voltage of a control system of the hybrid working machine.
2. The hybrid working machine according to claim 1, further comprising:
a regenerative resistor that consumes regenerative power when the rotation motor is performing a regenerative operation; and
regenerative-resistor controlling means for controlling the regenerative resistor.
3. The hybrid working machine according to claim 1, further comprising bus voltage detecting means for detecting the voltage of the direct current bus,
wherein the electric-storage-device breakdown detecting means detects that the electric storage device is unusable when the bus voltage detected by the bus voltage detecting means at start-up in a state in which the electric storage device is connected to the direct current bus is less than a set value.
