Why install reactive power compensation device?

reactive power compensation is a very traditional power technology. Many enterprises use reactive power compensation devices in their power systems, which have made great contributions to energy conservation and environmental protection. Therefore, it is very necessary to use reactive power compensation device. The main benefits of the installation of reactive power compensation device are as follows:

(1) The line loss is reduced by more than 5%. As far as the whole country is concerned, if the reactive line loss can be reduced by 5%, 5 billion kWh can be saved every year, which is equivalent to half of the power generation of the Three Gorges Project.

(2) Avoid fines. According to "Power Factor Adjustment Measures" issued by Ministry of Electric Power and Price Bureau, the electricity fee can be reduced by 1.1% when the power factor reaches .94 and increased by 15% when the power factor is .6. For example, the power factor of a 315KVA transformer is increased from .6 to more than .94, and the difference between reward and punishment of electricity fee for one year is 3, ~ 4, yuan.

(3) Improve the load-carrying rate of electricity consumption to achieve the effect of capacity expansion. For example, when the power factor of 315KVA transformer is .6, it can only provide 189KW active power, and the power factor is increased from .6 to .98, which is equivalent to an increase of 63%, that is, from 1898KW to 39KW.

(4) improve the power quality, prolong the service life of electrical appliances, and ensure the normal operation of electrical appliances.

(5) The reactive power compensation device can effectively reduce the faults of enterprise distribution transformers and reduce the loss of enterprise distribution. The use of low-voltage reactive power compensation device can improve the voltage quality at the end of enterprise power supply network. After the low-voltage reactive power compensation device is processed, the current on the circuit can be significantly reduced, the voltage consumption on the power grid line can be reduced, the terminal voltage of the power supply with lower voltage in the past can be improved, and the terminal voltage quality of the power supply can be improved.
