The Power Factor Correction Device Exists To Prevent Its Use From Being Restricted Due To Excessive Harmonics.

In power system design and power quality management, capacitor bank for power factor improvement, as part of power distribution and consumption equipment, helps to address harmonic problems caused by nonlinear loads in the power grid. As the proportion of nonlinear devices such as switching power supplies and frequency converters increases in industrial and commercial environments, the current waveform will exhibit high total harmonic distortion, which will affect the performance indicators of power equipment and power supply networks. For example, voltage fluctuations and equipment overheating are becoming increasingly important design considerations.

During product development planning, it has been observed that in many scenarios, harmonic levels in the power grid and terminal devices exceeding regulatory limits can interfere with the operation of power infrastructure. These regulations typically set permissible amplitudes for each harmonic component based on relevant standards to meet market access and long-term reliable operation requirements.

To address this scenario, by introducing power correction device at the system front end, the distortion component in the input current can be controlled when the device is connected to the power grid, reducing the injection of high-order harmonics into the power grid and improving the stability of the overall electrical parameters.
