Intelligent reactive power compensation capacitor bank

Product Uses: Intelligent reactive power compensation capacitor banks are “energy-saving experts” in power systems.


Their main functions are:

  • Compensating for reactive power losses in the power grid, improving the power factor, and avoiding power factor penalties for the power sector; (B) Reducing line losses and improving the power supply efficiency of the power grid;
  • Stabilizing the power grid voltage, protecting electrical equipment, and extending equipment lifespan. Product Image.

Core Components:

  • Intelligent Controller: Equivalent to the "brain" of the cabinet, it monitors the power factor, voltage, current, and other parameters of the power grid in real time and automatically switches capacitor banks.
  • Capacitor Banks: Reactive power "storage devices," switched according to  controller instructions to replenish the reactive power of the power grid.
  • Switching Switches: Commonly use thyristors or composite switches to achieve impact-free switching of capacitors, avoiding inrush current damage to equipment.
  • Fuses/Circuit Breakers: Provide overcurrent and short-circuit protection to ensure equipment safety.
  • Reactors: Suppress inrush current and power grid harmonics, protecting capacitors.


Customized adaptation to various scenarios: 

Based on your business in customizing electrical equipment, these cabinets can be tailored for different scenarios:

  • Hydropower scenario: Adapting to fluctuating loads of equipment such as pump stations and gates, customizing moisture-resistant and vibration-resistant cabinet structures, and enabling unattended operation with remote monitoring modules.
  • Industrial plant scenario: Designing group switching strategies for high-power inductive loads such as machine tools and air compressors, accurately compensating for reactive power.
  • Commercial building scenario: Customizing compact cabinets to fit the limited space of building power distribution rooms, and adding harmonic mitigation modules to handle nonlinear loads such as elevators and air conditioners.
