JKW—2SC Intelligent Reactive Power Compensator (Debugging Method)

The power factor is expressed by cosφφ, which indicates the proportion of active power in the line. When cos φ = 1, the line has no reactive power loss. Improving power factor to reduce reactive power loss is the ultimate goal of this kind of controller. This control mode is also very traditional, and sampling and control are also easy to realize. ?

"Delay" setting, the switching delay time should be adjusted within the range of 10s- 120s, and the current sensitivity should not be greater than 0-2A. The input and cut-off thresholds should be set with power factor in the range of 0.85 (lag) -0.95 (lead). Overvoltage protection setting, display setting, cycle switching and other functions.

This sampling method should not only ensure the stability and no oscillation of the line system, but also give consideration to the compensation effect. This is a contradiction. Only by setting parameters on the spot according to specific conditions can we work in a better state. No matter how good the adjustment is, it cannot make up for the defects of this method itself, especially when the line is overloaded.

Extended data:

Reactive power (reactive current) controller perfectly solves the defect of power factor type. A well-designed reactive power controller is intelligent and adaptable, which can give consideration to the stability of the line and the effect of detection and compensation, and can protect and detect the compensation device well. This controller generally has the following functions:

Four-quadrant operation, automatic manual switching, self-identification of power of each capacitor bank, automatic adjustment of switching time according to load, harmonic overvoltage alarm and protection, line resonance alarm, overvoltage protection, line small current alarm, voltage and current distortion rate measurement, display capacitor power, and display cosΦ φ, U, I, S, P, Q and frequency.

As can be seen from the above functions, its control function is complete, and because it is a reactive power controller, the role of the compensation device will be fully played.
