Main differences between mechanical speed regulation and electronic speed regulation
Published:

After starting the generator, it is necessary to adjust the speed to achieve a stable rated revolution. Only by ensuring the stability of the generator revolution can the stability of the output voltage and frequency be ensured. 2. Mechanical governors do not require power, only electronic governors require power. According to SOLAS requirements, if the emergency generator is equipped with an electronic governor, it is necessary to provide a set of independent storage batteries for the electronic governor, which are different from the starting batteries of the emergency generator. Therefore, emergency generators with electronic speed regulation need to be equipped with two sets of storage batteries. The principles of mechanical speed regulation and electronic speed regulation are actually very simple. 4. The rotational speed of the generator varies with the size of the throttle. Just like automotive engines, large throttle speeds increase the rotational speed, and vice versa. Therefore, whether mechanical or electronic speed regulation is ultimately achieved by controlling the throttle of the generator. "I have only touched on one type of mechanical speed regulation, which is to have a set of devices similar to a swing ball on the rotating shaft of the generator. Different rotational speeds can generate varying centrifugal forces, just like a lama's rotating cylinder. The faster the swing, the greater the angle at which the two swing balls swing apart. The throttle size of the generator can be adjusted through the angle of the swing ball.". Electronic speed regulation is simpler, with a speed sensor that controls the size of the throttle by controlling the servo motor to drive the rack based on the speed signal.
