1、 What is the rated power factor of a generator set ?

The rated power factor of a generator refers to its ability to output effective power at its rated capacity. In practical use, the power factor of a dg generator is generally 0.8 or 1.0. Among them, a power factor of 0.8 refers to the ratio of the product of the active power output at the rated capacity of the genset to the rated capacity; A power factor of 1.0 refers to the active power output by the diesel generator at rated capacity being equal to the rated capacity.

2、 What is the impact of power factor on generators?

Power factor is one of the important factors that determine the efficiency and power quality of a generator. If the power factor of the generator is low, the required reactive power will increase correspondingly when outputting the same active power, which will lead to a decrease in the power quality of the generator and may even affect the normal operation of the power system. Therefore, choosing the appropriate power factor is very important.

3、 How to improve the power factor of the generator?

There are two methods to improve the power factor of a generator: one is to increase the active power of the generator, and the other is to reduce the reactive power of the generator.

To increase active power, methods such as increasing generator capacity and increasing the cross-sectional area of rotor wires can be used. Reducing reactive power can be achieved through methods such as capacitor bank parallel compensation and adjusting excitation current. The specific method can be selected according to the actual situation.

Conclusion

The rated power factor of a generator is an important factor in ensuring its efficiency and power quality. A lower power factor may affect the power quality of the generator and the normal operation of the power system. Therefore, selecting a suitable power factor is very important. In order to improve power factor, measures such as increasing active power and reducing reactive power can be taken.
