伝送装置。A power detection circuit detects active power by obtaining voltage and current signals from each engine generator in parallel operation, and comparison with the active power of other engine generators obtained through signal lines connected to each engine generator. After that, in an automatic load sharing device equipped with a judgment circuit that appropriately controls the frequency in order to equalize the load factor of each engine generator, the output of the power detection circuit is converted to an A/D converter. Convert it to a digital signal, and combine this with a digital signal for generator identification.
The block is repeatedly transmitted to each engine generator in sequence, and the load factor of each generator in the digital signal is sequentially received from each engine generator to calculate the average load factor of the generators running in parallel and the load factor of the own generator. A signal transmission device for an engine generator, characterized in that a signal transmission device for an engine generator is characterized in that a comparison operation is performed, the signal is converted into an analog signal by a D-converter, and then the signal is transmitted to the determination circuit.
