Reactive Power Compensation Automatic Controller
JKWF
The JKWF series automatic reactive power compensation phase controller (hereinafter referred to as the controller) uses a high-performance microprocessor as its core component and simultaneously selects three-phase voltage and three-phase current models. It has up to 16 output circuits and can realize full phase compensation, full common compensation, and common compensation + phase compensation modes. It also provides 12 capacitor combination methods (capacity coding), which users can select by modifying control parameters; once modified, the settings are permanently saved. The controller combines fundamental power factor and fundamental reactive power to control capacitor bank switching, ensuring stable switching without oscillation, insensitivity to harmonics, and accurate display of power data and control of switching. It is suitable for automatic control of reactive power compensation in 0.4KV systems.
1. Controlling capacitor bank switching based on fundamental power factor and reactive power avoids various forms of switching oscillations and accurately displays power data and controls capacitor bank switching even in the presence of harmonics.
2. High power factor measurement accuracy and wide display range.
3. 12 capacitor capacity codes are available for user selection.
4. Up to 16 output circuits can be controlled, and sub-compensation and common compensation circuits can be modified arbitrarily within this range.
5. Automatic and manual operation modes are available and can be memorized.
6. An optional passive alarm output port can be installed, and the alarm type can be selected through programming. Alarm Events
7. Control parameter memory, not lost during power outages
8. Overvoltage, undervoltage, voltage harmonic over-limit, current harmonic over-limit, and temperature over-limit protection functions
