Name: GY-ASVG-1U Max-thin Advanced Static Var Generator - GEYA Electrical Equipment Supply
SKU: GY-ASVG-1U

Description

Overview

The GY-ASVG-1U Rack-Mount Advanced Static Var Generator is a highly efficient power quality solution featuring a compact 1U thickness design. Engineered for modern power grids, this advanced static var generator connects a voltage source converter (VSC) in parallel to deliver real-time, comprehensive compensation for reactive current, harmonic current, and three-phase unbalanced active power. Its space-saving form factor allows for more units to be accommodated within a single cabinet, making it an excellent choice for high-density industrial and commercial applications.

Working Principle

The device continuously detects the load current in real time. Based on advanced detection and control algorithms for reactive power, harmonics, and three-phase active power, it generates corresponding IGBT drive signals. This enables precise compensation to maintain optimal power quality, stabilize the grid, and improve overall energy efficiency.

Key Features

High-Density 1U Form Factor: The 1U thickness design significantly reduces footprint, allowing seamless integration into standard racks and maximizing cabinet space utilization.
Multi-Module Parallel Support: Modular architecture allows for multi-module parallel connections with no quantity restrictions, facilitating easy maintenance and scalable capacity upgrades.
Advanced Digital Control: Utilizes a DSP+CPLD full-digital control core combined with three-level topology technology and advanced PWM control strategies.
Versatile Compensation Modes: Supports any single, dual, or triple combination of reactive power compensation, harmonic compensation, and three-phase unbalance compensation.
Exceptional Performance: Delivers ≥99% reactive power compensation, ≥95% harmonic compensation (adjustable for 2nd to 50th harmonics), and reduces unbalance degree to ≤5% after compensation.
Robust Reliability: Features 100% current-limiting output to ensure long-term stability, alongside comprehensive protection against overload, overcurrent, over/undervoltage, and resonance.

1. What is the GY-ASVG-1U?

The GY-ASVG-1U is an advanced static var generator featuring a highly compact 1U (44.5mm) thickness design. It is engineered for rack-mount installations, allowing multiple units to be integrated into a single high-density cabinet to improve power quality efficiently.

2. What core functions does it provide?

It provides comprehensive real-time compensation for modern power grids. Its core functions include reactive power compensation (≥99%), harmonic current filtering (from the 2nd to the 50th harmonic with ≥95% efficiency), and three-phase unbalance correction (reducing unbalance to ≤5%).

3. What are the key parameters affecting customer selection?

When selecting this device, customers should consider the operating voltage (220V or 380V), required compensation capacity (3Kvar or 5Kvar per unit), grid configuration (3-phase 3-wire or 4-wire), and the physical installation space, as its 1U design and unrestricted parallel capabilities make it ideal for space-constrained environments.

4. What options and specifications are currently available?

The GY-ASVG-1U is available in two main configurations: a 220V model with 3Kvar capacity and a 380V model with 5Kvar capacity. Customers can choose between rack-mount (rear cable entry) or wall-mount (top cable entry) installations. The standard protection rating is IP20, but IP54 is available upon request.

5. What standards does it meet, and for which markets is it designed?

Designed for high-end industrial and commercial markets requiring strict power quality management, it features a DSP+CPLD control core and three-level topology. It meets stringent grid standards with an overall efficiency of ≥97%, low noise (≤60dB), and robust protection mechanisms, making it suitable for global data centers, manufacturing facilities, and commercial buildings.

6. What are the precautions for installation and maintenance?

Ensure the installation environment maintains an ambient temperature between -10°C and +50°C (derating required above 40°C) and relative humidity ≤90% without condensation. For altitudes above 2000m, derating is necessary according to GB/T 3859.2. Thanks to its modular 1U design, maintenance is straightforward, but proper ventilation within the cabinet must be ensured for optimal heat dissipation.
