Product Features
Overview
Enhanced Static Var Generator (GY-ASVG) is mainly composed of an AC distribution unit, ASVG modules, a monitoring system, etc. The GYASVG connects a voltage source converter (VSC) to the power grid via a filter in parallel. Its working principle is to detect the load current in real time and, based on advanced detection and control algorithms for reactive power, harmonics, and three-phase active power, generate corresponding IGBT drive signals to achieve comprehensive compensation of reactive current, harmonic current, and three-phase unbalanced current. The device adopts a modular design, offering high integration density as well as convenient and flexible installation.
Performance characteristics
(1) DSP+CPLD full-digital control core, three-level topology technology.
