Product Features
Overview
Working Principle of the High-configuration Model Enhanced Static Var Generator (GY-ASVG-PLUS):
The device connects a voltage source converter (VSC) to the power grid via a filter in parallel. By detecting the load current in real time and based on advanced detection and control algorithms for reactive power, harmonics, and three-phase active power, it generates corresponding IGBT drive signals to achieve comprehensive compensation of reactive current, harmonic current, and three-phase unbalanced current. In addition, the device’s neutral line zero-sequence current filtering capability can reach three times the phase line current. It also offers better EMC electromagnetic compatibility performance and improved stability.
