Diesel Generator Tech

Working principle of AVR The voltage regulator is an adjustment device that controls the generator output voltage within a specified range. Its function is to automatically control the generator voltage and keep it constant when the rotating speed of the generator changes, so as to prevent the generator voltage from being too high to burn out the electrical equipment and cause the battery to overcharge. At the same time, it also prevents the generator voltage from being too low, resulting in malfunctioning of electrical equipment and insufficient battery charge. Since the transmission ratio of generator to engine is fixed, the speed of generator will change with the change of engine speed. The power supply of generator to electric equipment and charging to battery both require its voltage to be stable, so it is necessary to adjust the output voltage of generator if the voltage is kept at a certain value basically. A synchronous generator regulator that maintains the sync...

Our company produces generator sets, some of which are equipped with mechanical governors and some with electronic governors. Both speed governors can guarantee the power quality absolutely, but the generator set equipped with electronic governor realizes automatic protection and automatic control is very convenient. The electronic governor of diesel generator set has been adjusted and the user does not need to do this. However, after the engine overhaul or the fault that affects the operation of the electronic governor, it needs to be adjusted. The electronic governor control unit is mounted in the control box at the top of the generator. A. Turn switch C1 to the engaged position. If there is rapid ride during the engine running, turn C2 to the (OFF) position. B. Turn switch C2 to the engaged position. C. Turn the gain (GAN) and stability potention meters to the middle position. D. Temporarily connect terminals L and M together. Adjustment of the electronic governor a...
