置。 An engine that is rotationally driven using digestion gas as fuel, an induction generator that is rotationally driven by this engine, and the induction power generation is performed by detecting that the rotational speed of the engine has reached the vicinity of the synchronous speed of the induction generator. A synchronization control device for a power generation device comprising a speed relay connecting a machine to the engine includes a rotation speed sensor that detects the rotation speed of the engine and generates a pulse detection signal, and a rotation speed sensor that detects the rotation speed of the engine and generates a pulse detection signal. A pulse/BCD converter for converting into a binary encoded decimal signal, and this pulse/BCD converter.
The deviation value between the BCD detection value obtained by the CD converter and the synchronous speed setting value is calculated, and when this deviation value is positive, a speed increase command is issued to control the governor of the engine, and the deviation value is When the deviation value is negative, a deceleration command is issued to control the governor, and when the deviation value is below a dead band of the rotational speed of the engine, the speed relay is turned on by the arithmetic control section that connects the induction generator to the engine. 1. A synchronous input control device for a digestion gas power generation device, characterized in that:
