Q: Dingfeng Capacitor -- What is the role of power capacitors?
A: Power capacitors are divided into series capacitors and shunt capacitors. They are used to improve the voltage quality of the power system and improve the transmission capacity of the transmission line.
The role of the series capacitor:
1. Increase the voltage at the end of the line.
2. Reduce voltage fluctuations at the receiving end.
3. Improve the transmission capacity of the line.
4. Improved system power flow distribution.
5. Improve the stability of the system.
The role of shunt capacitors:
The shunt capacitor absorbs the capacitive reactive power of the system, which is equivalent to the inductive reactive power of the shunt capacitor to the system. Therefore, the shunt capacitor can provide inductive reactive power to the system, the power factor of the system operation, and increase the voltage level of the busbar at the receiving end. At the same time, it reduces the transmission of inductive reactive power on the line, reducing voltage and power loss, because the transmission capacity of the line is improved.
