Effects of high or low frequency on generator sets

When it comes to the frequency of generator sets , many uninformed customers will think that the higher the frequency, the better. However, after long-term use, the generator set is damaged. Jiangsu Haixing Power summarized this technical article for your reference for this type of customer, so that customers can promptly discover unit problems during use and reduce maintenance costs.

Generally, the frequency of the generator set should not exceed 52.5HZ, i.e. 5% of the rated value. Therefore, if an abnormality in the frequency of the generator set is found during use, timely measures should be taken.

When the frequency increases, it is mainly limited by the rotational mechanical strength. The high frequency and the motor speed are high. When the speed is high, the centrifugal force on the rotor increases, which easily causes damage to some parts of the rotor.

When the frequency decreases, the following problems will occur:
(1) The decrease in frequency causes the rotor speed to decrease, which reduces the air inlet of the fans at both ends, which deteriorates the generator's cooling conditions and increases the temperature of each part.
(2) The frequency is low, causing the temperature of the rotor coil to increase, otherwise the output will be reduced.
(3) Low frequency may also cause the steam engine to break the blade.
(4) When the frequency decreases, in order to keep the terminal voltage unchanged, the magnetic flux must be increased, which can easily saturate the stator core and escape the magnetic flux, causing some structural components of the machine to produce local high temperatures, and some parts even sparks.
(5) When the frequency is low, the speed of the factory motor decreases, resulting in a decrease in output, which also has a negative impact on the safety of users' electricity, product quality, efficiency, etc.
(6) The frequency is low and the voltage is also low. This is because the magnitude of the induced potential is related to the rotation speed. At the same time, the low speed of the generator also reduces the output of the coaxial exciter, affecting the output of the reactive power.

Both high or low frequency have an impact on the quality of electricity consumption and can sometimes burn out the electrical equipment.
