1. A cogeneration apparatus having an engine, an electric generator driven by the engine, a system linkage control unit which links an electric power generation output from the electric generator with a power system, and an exhaust heat recovery unit which recovers exhaust heat from the engine, comprising:
means for raising an upper limit of a rotating speed of the engine to an upper limit higher than that in a system linkage state to enable to perform an operation at a raised maximum output point of the electric generator in an independent operation state in which the cogeneration apparatus is operated independently of the system, said means comprises:
means for supplying a signal that corresponds to a value higher than the upper limit in the system linkage state to a stepping means, said stepping means controls the rotating speed of the electric generator in the independent operation state to said value.
