Power Compensation Controller

In modern industrial power systems, the stability of low-voltage reactive power compensation is facing extremely severe challenges. With the widespread application of non-linear loads such as frequency conversion equipment and rectifier devices, grid harmonic pollution has become increasingly prevalent. In this environment, traditional Power Compensation Controllers often exhibit oscillations where capacitor banks are repeatedly switched on and off and operate frequently. These oscillations not only affect the compensation effect but also shorten the lifespan of equipment and even endanger the safe operation of the power grid. As a professional manufacturer in the field of low-voltage reactive power compensation in China, Geyue Electric has deeply understood this industry pain point and, relying on its independently developed JKWF series Power Compensation Controller, has provided an innovative solution.

Most traditional Power Compensation Controllers directly calculate the total power factor, total reactive power and the capacity to be compensated using the total current and voltage signals of the power grid. This calculation method is still applicable in a pure power grid, but it has obvious drawbacks in a harmonic environment. In a harmonic environment, harmonic currents will seriously interfere with the measurement accuracy of the traditional controller for the total reactive power and total power factor of the power grid, causing the controller to be unable to accurately identify the true reactive power demand. This is precisely the main reason for the incorrect operation of capacitor banks and oscillations in switching. After reaching this understanding, Geyue Electric immediately shifted the research focus of the Power Compensation Controller to a more fundamental solution, that is, bypassing the "surface" signals polluted by harmonics and directly measuring and responding to the "root" of the power grid's reactive demand.

The key technological breakthrough of the Geyue Electric’s JKWF series Power Compensation Controllers lies in the adoption of advanced digital signal processing technology. This series of controllers can accurately separate the 50Hz fundamental component from the complex grid waveform and filter out all harmonic interference. This technology enables the Geyue Electric’s JKWF series Power Compensation Controllers to obtain pure fundamental voltage and fundamental current signals, laying a solid foundation for precise calculations. Through this innovative signal processing method, the Geyue Electric’s JKWF series has achieved a precise grasp of the essence of the grid state.

Based on pure fundamental wave signals, the Geyue Electric’s JKWF series Power Compensation Controllers innovatively adopt a composite control algorithm that uses both fundamental power factor and fundamental reactive power as dual criteria. This dual criterion design is like equipping the controllers with dual safeguards, enabling the controllers to not only master the overall compensation status of the system through the fundamental power factor, but also precisely calculate the required compensation capacity through the fundamental reactive power. The innovative composite algorithm implanted in the JKWF series Power Compensation Controllers make a certain that the controllers can make the most reasonable capacitor switching decisions under any load conditions.

The Geyue Electric’s JKWF series Power Compensation Controllers eliminate the oscillation problems caused by harmonics through precise calculation of fundamental reactive power. Since the controllers only respond to the actual fundamental reactive power demand and are completely immune to instantaneous fluctuations caused by harmonics, they can maintain a stable capacitor switching rhythm. In practical applications, the Geyue Electric’s JKWF series Power Compensation Controllers demonstrate outstanding stability and significantly extend the service life of capacitors and switching devices.

In industrial sites with severe harmonic pollution, the Geyue Electric’s JKWF series Power Compensation Controllers demonstrate remarkable adaptability. This series of controllers not only can accurately display the actual fundamental power factor, but also can maintain stable control performance even under harmonic interference. This powerful anti-interference capability makes the Geyue Electric’s JKWF series Power Compensation Controllers particularly suitable for industries with severe harmonics such as metallurgy, chemical industry, and mechanical manufacturing.
