Hydrogen mixed-combustion electronic control device and power generation system using same

A hydrogen mixed-combustion electronic control device that controls a mixed ratio of hydrogen mixedly combusted in a combustion room of a hydrogen mixed-combustion engine,

• the hydrogen mixed-combustion engine including a first fuel supply device configured to supply a first fuel to an engine, and a second fuel supply device configured to supply, as a second fuel, fuel partially containing hydrogen to the engine,
• the hydrogen mixed-combustion electronic control device comprising:
• a crank angle sensor that detects a rotation time of a crank shaft of the engine;
• and
• a computation unit that computes an extreme value of the rotation time of the crank shaft and an extreme value timing based on a detection result of the crank angle sensor,
• wherein the hydrogen mixed-combustion electronic control device determines a combustion state of the engine based on the extreme value and the extreme value timing.
