Power factor is a coefficient to measure the utilization efficiency of enterprise electric power equipment. If the power factor, the utilization rate of enterprise power equipment will be reduced, the normal production of enterprises will be affected. In the following article, small library will introduce the reasons for enterprises to improve the power factor in detail, and the way to improve the power factor, I hope to help you.

1, why to improve the power factor

The output of the generator is reduced. If the reactive power in the power system is provided by the generator, the active power output of the generator will be reduced. As the output of generator decreases, the operation of electric power equipment will be affected to a certain extent.

② Increase in electricity charges. When the power factor is low, the power bureau will increase the income to the enterprise to adjust the electricity charge; If the power factor reaches the specified standard, the enterprise not only does not need to pay the power adjustment electricity fee, but also can obtain a certain proportion of electricity fee reduction.

③ Lower investment costs. If reactive power compensation is designed during the reconstruction of the new project, the design capacity of transformer can be reduced. In this way, enterprises can save investment in transformers, cables and so on.

2, the way to improve the power factor

At present, there are two ways to improve the power factor commonly used by enterprises. They are: improve the natural power factor and install reactive power compensation device.

① Improve the natural power factor. To improve the natural power factor of the power grid, we can improve the natural power factor of the power grid by rational use of motors, avoiding no-load or light-load operation of asynchronous motors, and reasonable selection of equipment capacity.

Install reactive power compensation device. In addition to improving the natural power factor, enterprises can also improve the power factor through power capacitors, smart capacitors, SVG static reactive power generators and other reactive power compensation devices.

For enterprises, the importance of power factor is self-evident. The installation of reactive power compensation devices, such as power capacitors, can improve the power factor of enterprises, improve the power quality, thus improving the economic benefits of enterprises, and make the power system run stably for a long time.
