Description

The GY-ASVG-PLUS High-Spec Advanced Static Var Generator is a premium power quality solution integrating reactive power compensation, harmonic filtering, and three-phase unbalance correction. Featuring ≥98% efficiency, 3× neutral line filtering, and EMC Class A compliance, this DSP+CPLD controlled module ensures ultimate grid stability for industrial applications.

Overview: The Best of Both Worlds
The GY-ASVG-PLUS merges the 3-in-1 versatility of the standard ASVG with the premium hardware of the SVG-PLUS. It delivers comprehensive compensation with upgraded efficiency, dual external CT channels, and superior electromagnetic compatibility.

Working Principle

Connected in parallel via a VSC and LCL filter, it detects load currents in real-time. Using advanced DSP+CPLD algorithms, it dynamically injects compensatory currents to instantly correct reactive power, harmonics, and unbalance—completely eliminating over/under-compensation.

Key Performance

3-in-1 Compensation: Reactive (≥99%) + Harmonics (≥95%) + Unbalance (≤5%).
Ultra-Fast Response: Transient <50µs, Full response <10ms.
Enhanced Neutral Filtering: 3× phase line capacity, ideal for 3P4W grids.
Dual CT Channels: Flexible HV/LV side sampling and component compensation.
Industrial Reliability: ≥98% efficiency, independent air ducts, and EMC Class A certified.

1. What is the GY-ASVG-PLUS?

The GY-ASVG-PLUS is a high-specification Advanced Static Var Generator. It combines the 3-in-1 compensation capabilities of an ASVG with the upgraded hardware of a PLUS model. Built on a DSP+CPLD three-level digital control core, it connects a voltage source converter in parallel with the grid to dynamically compensate reactive current, harmonic current, and three-phase unbalanced current, while offering enhanced efficiency (≥98%) and superior neutral line filtering.

2. What core functions does it provide?

It delivers a comprehensive 3-in-1 power quality solution: real-time reactive power compensation (≥99%), current harmonic filtering (≥95%, 2nd–50th order), and three-phase unbalance correction (residual ≤5%). Additionally, it provides an exceptional neutral-line zero-sequence current filtering capacity of 3 times the phase line, dual external CT channels for flexible sampling, and comprehensive system protection.

3. What are the key parameters that affect model selection?

Key factors include the operating grid voltage (220V or 380V), grid configuration (3P3W or 3P4W), and the required compensation capacity (kvar). You should also consider the installation environment (ambient temperature, altitude derating above 2000m, IP rating), form factor (rack-mounted vs. wall-mounted), and your specific compensation goals (reactive, harmonics, unbalance, or a combination).

4. What options and specifications are available?

The GY-ASVG-PLUS is available in 220V models (37 kvar, 50 kvar) and 380V models (75 kvar, 100 kvar). Users can select between rack-mounted (rear cable entry) and wall-mounted (top cable entry) modules. The standard protection rating is IP20, with IP54 available upon request. Modules support unlimited parallel connections for expanded capacity.

5. Which international standards does it meet and which markets is it designed for?

The device is designed to meet strict international power-quality and EMC standards, specifically achieving EMC Class A for both Radiated Emission (RE) and Conducted Emission (CE). Altitude derating complies with GB/T 3859.2. It is engineered for demanding industrial and commercial markets globally, including manufacturing plants, EV charging stations, renewable energy integration, data centers, and metallurgy.

6. What are the installation and maintenance precautions?

The unit must be wired in parallel with the load. Before commissioning, confirm the grid voltage, 3P3W/3P4W configuration, and verify the polarity and ratio of the dual external CT channels. Ensure proper ventilation for the independent air ducts and maintain ambient temperatures between -10°C and +50°C. Reliable PE grounding is mandatory for EMC performance. For maintenance, periodically clean the air filters; the modular design allows for quick plug-in replacement to minimize downtime.
