Setting the Frequency Variation of Volvo Diesel Generators

Aug. 11, 2023

What should Volvo diesel generators pay attention to adjusting their frequency changes? We believe that frequency changes will have adverse effects on users, Volvo diesel generator plants, and electrical equipment. Therefore, it is necessary to adhere to the frequency being above or below the rated value of 50HZ, and the deviation should not exceed a certain range. When the frequency of the power system changes, the impact on users is as follows: firstly, the speed of the Volvo diesel generator used by users is related to the system frequency, and the frequency change will affect the speed of the Volvo diesel generator, thereby affecting the quality of the product.

Secondly, the instability of the system frequency will affect the normal operation of electronic devices. If the main mechanical equipment used in the Volvo generator plant, such as fans and fans, are reduced in frequency, the air and water supply will rapidly decrease, affecting the normal operation of the boiler. When operating at low frequencies, it will increase the pressure borne by the turbine blades, trigger resonance of the blades, shorten the lifespan of the blades, and even cause the blades to fracture. If the ventilation capacity of the Volvo diesel generator is reduced during low-frequency operation, in order to maintain normal voltage, it is requested to increase the excitation current to increase the temperature rise of the top and rotor of the Volvo diesel generator. In order to not exceed the temperature rise limit, the power generation capacity of the Volvo diesel generator has to be reduced.


When operating at low frequencies, the core loss and excitation current of the transformer will increase due to the increase in magnetic flux density. In order to not exceed the temperature rise limit, the transformer load has to be reduced. When the frequency decreases, the manufacturer of Volvo diesel generators indicates that the reactive power load in the system will increase, leading to a decrease in system voltage level. In short, since all equipment is set according to the rated frequency of the system, the decline in system frequency quality will affect various industries. When the frequency is too low, it can even cause the entire system to collapse.
