power capacitor
The core role of power capacitors in the power system is to perform reactive power compensation, improve voltage quality, reduce line losses, and enhance system stability.
Power capacitors have been widely used in industrial production, commercial electricity, residential electricity, power plants, substations and other fields.
Main functional role:
Improve power factor: Compensate for inductive reactive power in the power grid to achieve the specified range of power factor and avoid electricity fines.
Improving voltage quality: When the voltage is low, release reactive power to increase the voltage, and when the voltage is high, absorb reactive power to decrease the voltage.
Reduce line losses: After reactive power compensation, the total current of the line decreases, and according to the formula P=I ² R, the active power loss of the line decreases.
Improve system stability: Provide instantaneous reactive power support to help the system cope with load changes and instantaneous disturbances.
Suppressing resonance: Interacting with inductive and resistive components to suppress resonance phenomena.
