1. Hybrid var compensator Overview

Hybrid var compensator(HVC) combines the technical advantages of AHF and SVG with the cost-effectiveness of a traditional contactor or thyristor switch detuning filter capacitor bank to form an economic stepless real-time compensator.
Hybrid var compensator(HVC) offer different functions:

  • Eliminate harmonic current and voltage
  • Power factor correction (lag or lead)
  • Load balancing in the three-phase system

Hybrid var compensator(HVC) can prolong equipment life, improve process reliability, improve power system capacity and stability, and reduce energy loss.
Enjoypowers’ AHF and SVG all support hybrid var compensator(HVC) solution. It is a cost-effective power quality solution for all power consumers, system integrators, and OEMs.

2. Hybrid var compensator Operating principle

HVC uses the capacitor bank steps to fulfill the maximum capacitive reactive power requirements of the power system, and the AHF and SVG in the HVC take care of the extra continuous compensation (capacitive or inductive) required.At the same time, the HVC can filter out the harmonics of the system and reduce the three-phase unbalance.
Capacitor banks in HVC are directly controlled by AHF and SVG through RS485 or DO signals, RS485 is used for intelligent capacitors, and DO signals are used for ordinary capacitors.
