Abstract
Provided are a method and a device for controlling an internal combustion engine driven generator set to run in parallel. The method includes: each time an internal combustion engine is started, a controller detects whether a voltage is outputted in an output voltage circuit; obtaining of respective active power and effective values of output currents; seeking of corresponding output voltage amplitudes in respective droop characteristic curves according to the effective values of the respective output currents, and seeking of corresponding inner power factor angles in the respective droop characteristic curves according to the respective active power; the droop characteristic curves of each generator have the same slope; and each generator is controlled to reach the respective corresponding output voltage amplitudes and inner power factor angles.
