Description
The GY-ASVG-LN Low-noise Advanced Static Var Generator is an ultra-quiet, compact power quality solution tailored for commercial and residential applications. By integrating reactive power compensation, active harmonic filtering, and three-phase unbalance correction into a single device with noise levels as low as 38dB, it ensures optimal grid stability without disrupting the acoustic environment.
Overview & Working Principle
The GY-ASVG-LN connects a voltage source converter (VSC) to the power grid via a filter in parallel. Utilizing its built-in grid-side sampling CT, it detects the load current in real-time. Based on advanced DSP+CPLD detection and control algorithms for reactive power, harmonics, and three-phase active power, it generates corresponding IGBT drive signals. This enables the device to achieve dynamic, comprehensive compensation of reactive current, harmonic current, and three-phase unbalanced active power.
Key Performance Characteristics
- â—†Ultra-Quiet Operation: Specifically optimized for noise reduction, keeping operational noise between 38dB and 45dB depending on the capacity.
- â—†Built-in Sampling CT: Unlike standard models requiring external CTs, the LN series features a built-in grid-side CT, saving installation time and space.
- ◆3-in-1 Flexible Compensation: Supports any combination of reactive power (≥99%), harmonics (≥95%), and unbalance (≤5%) compensation.
- ◆Space-Saving Design: With dimensions of just 390×525×90.2mm, it easily fits into tight commercial distribution cabinets.
- â—†100% Current-Limiting Output: Ensures long-term stable operation by preventing equipment overload.
GY-ASVG-LN vs. GY-ASVG-SiC: Which to Choose?
While both models offer premium 3-in-1 power quality compensation, they are designed for entirely different application scenarios.
The GY-ASVG-SiC is an industrial powerhouse. Utilizing Silicon Carbide technology, it handles massive capacities (up to 100kvar per module), delivers peak efficiency (>98.5%), and offers 3× neutral line filtering. It is the go-to choice for heavy industrial plants, EV charging stations, and metallurgy.
In contrast, the GY-ASVG-LN (Low-Noise) is engineered for acoustic comfort and smaller loads (2kvar to 10kvar). With its whisper-quiet operation (≤38-45dB) and built-in CT, it is the perfect, unobtrusive solution for noise-sensitive environments like hospitals, office buildings, residential complexes, and commercial data rooms.
