To provide an operation controller for a generator, which can operate the generator by freely changing the generated power value of the generator corresponding to a change in a loading pattern even on the occurrence of variations in the load pattern of the generator, can simplify and facilitate the control of a generating apparatus, and can be easily applied to the generating apparatus capable of selecting/using both of the received electric value from the outside and the electric power generated by the generator.

The operation controller for a generator is constituted so that a generated power setting value is transmitted to a generator control board via a communication means from a remote control terminal, and the generator is operated/controlled by a generated power control signal calculated on the basis of the generated power setting value in the generator control board. The generator control board is provided with a computer having a generated power target value computing means for computing the generated power target value of the generator on the basis of the generated power setting value from the remote control terminal, and having a generated power setting value restoring means for restoring the generated power setting value, and with a control sequencer for operating/controlling the plurality of generators based on the generated power target value which is input from the computer.
