Functions of Reactive Power Automatic Compensation Controller
- Adopting AC sampling technology.
- A Using fundamental power factor and fundamental reactive power as control physical quantities, highcontrol accuracy, no switching oscillation, and insensitive to harmonics.
- All digital operation of control parameters, easy to use, one step in place, without losing power outage data.
- Adopting automatic optimization control to reduce switching frequency and improve the service life ofthe system.
- Strong anti-interference ability, able to withstand 2000V interference pulses directly input from the powerAsupply, without crashing or losing data, stable and reliable operation;A Digital display of power factor, reactive power, voltage, current (primary side), control parameters of thepower grid.
- There are two working modes: power factor mode and reactive power control mode, which are convenientfor users to install and debug.
- lt has the function of judging and displaying overvoltage and undervoltage, and quickly cuting off thecapacitor bank to prevent the capacitor bank from operating under overvoltage conditions.
- With optional switching oscillation locking function (users need to indicate when ordering).
- With the optional function of delaying a 200 second delay from the cutting off time to the input time of asingle set of capacitors, there is sufficient discharge time after the capacitor bank is cut off, reducing theimpact on the power grid when the capacitors are put into operation again (users need to specify when ordering).
- The input resistance of the current sampling signal is less than 0.05 ohms and can be directly taken outAof the metering circuit.
- There are two compensation modes: power factor and reactive power.
- The user manual provides a large number of troubleshooting methods for easy installation and debugging.
Principle of Reactive Power Automatic Compensation Controller
The low-voltage reactive power automatic compensation controller determines the phase difference between the current in one line (for example, Line A) being sampled in the three-phase power supply with respect to the voltages of the other two lines (for example, Lines B and C). After some calculation is performed, the real-time power factor of the current power grid is determined. It then compares this power factor against the set switching-in and switching-out thresholds. During the entire duration of the switching delay, if the power factor is within the switching threshold, no action will be taken. If it is less than the switching-in threshold, one group of capacitors will be switched in. If it is greater than the switching-out threshold or if the power factor is ever found to be negative, one group of already switched-in capacitors will be switched out. The whole comparisons and switching action are repeated after the next switching delay until the current power factor is found to be within the switching threshold.
During switching, in case the voltage observed is more than the corresponding overvoltage protection threshold installed, all the already connected capacitors will be switched out group-wise; however, if the voltage rises beyond 10% of the selected overvoltage protection threshold, entire switching will take place in respect of already switched-on capacitors as a safeguard for the capacitors. In case undervoltage lockout is detected in the switching voltage while switching, the action will be interrupted to protect the system from cycling switching.

Our quality is reflected in the details
The wiring ports of the JKW5C series reactive power automatic compensation controller are cleanly arranged and labeled, which is a great benefit. First, a cleanly arranged wiring port layout intuitively leads one in the wiring process, hence reducing wiring mistakes and increasing overall installation efficiency. Second, the neat labeling and arrangement will allow easy identification of the wiring ports by maintenance personnel, thereby speeding up troubleshooting and daily maintenance, saving valuable time and labor costs. Furthermore, the neat wiring design reduces cable interference and crossing while increasing the stability and safety of the system, all contributing to the reliable operation of the equipment. Lastly, good wiring management plus enhanced aesthetics will make a professional impression on the users.
The JKW5C series reactive power automatic compensation controller has silicone buttons, which have many significant advantages. First of all, the silicone buttons are soft to the touch and comfortable to operate, thus effectively reducing user fatigue during long-term use. Secondly, the silicone material will have good water and dust resistance so as to ensure a good use condition even in harsh environments, thereby extending the service life of the equipment. In addition, the silicone buttons are highly wear-resistant and withstand frequent pressing without being easily damaged, which greatly assures stability and reliability in the operation of controller equipment. Finally, silicone button design is flexible and diverse such that users can optimally customize them by color and form which create a better aesthetic and personalization experience of products.
The control panel of the JKW5C series reactive power automatic compensation controller is clearly designed, and the buttons are neatly arranged, which is a considerably user-friendly operating system. First, everything is reasonably arranged on the control panel, and the function buttons with indicator lights can be clearly seen at a glance for the user to quickly locate whatever he wants to do and thus reduce confusion and misoperation during operation. Second, not only is this aesthetically pleasing, a neat button arrangement also guarantees that the user can react quickly to an emergency situation, making operation effective and safe. The clear identification and logical grouping of functions further allow users new to the system to operate it quite easily, and therefore cut back on training costs. All in all, the design promotes ease of use of the equipment and, as a result, enhances user confidence and satisfaction.
