The impact of high or low frequency on the generator set

speaking ofGenerator setFrequency, many inexperienced customers will think: the higher the frequency, the better. However, after long-term useGenerator setDamage occurs. Jiangsu Haixing Power has summarized this technical article for your reference for this type of customers, so that customers can timely detect unit problems during use and reduce maintenance costs.

Generally, the frequency of the generator set should not exceed 52.5HZ, which is 5% more than the rated value. Therefore, if the frequency of the generator set is found to be abnormal during use, measures must be taken promptly.

When the frequency increases, it is mainly limited by the strength of the rotating machinery. When the frequency is high, the motor speed is high. When the speed is high, the centrifugal force on the rotor increases, which easily damages some parts of the rotor.

When the frequency is reduced, the following problems will occur:
(1) The decrease in frequency causes the rotation speed of the rotor to decrease, which reduces the air volume blown by the fans at both ends, worsens the cooling conditions of the generator, and increases the temperature of each part.
(2) The low frequency causes the temperature of the rotor coil to increase, otherwise the output will have to be reduced.
(3) Low frequency may also cause turbine blades to break.
(4) When the frequency decreases, in order to keep the terminal voltage constant, the magnetic flux must be increased, which will easily saturate the stator core and cause the magnetic flux to escape, causing local high temperatures to occur in some structural parts of the machine base. Even sparks.
(5) When the frequency is low, the rotation speed of the factory motor decreases, resulting in a decrease in output, which also has a negative impact on the safety of users' electricity use, product quality, efficiency, etc.
(6) The frequency is low and the voltage is also low. This is because the magnitude of the induced electromotive force is related to the rotation speed. At the same time, the low rotation speed of the generator also reduces the output of the coaxial exciter and affects the reactive power output.

Whether the frequency is high or low, it affects the quality of power consumption and can sometimes burn out electrical equipment.
