Static Var Generator SVG 20kvar Wall Mounted Reactive Compensation Unit for Wastewater Treatment Plant

Static Var Generator SVG 20kvar Wall Mounted Reactive Compensation Unit for Wastewater Treatment Plant

Product Description :

Designed specifically for water treatment plants, this wall-mounted SVG optimises the power factor of pumps and blowers used in continuous processing lines. It improves overall system efficiency and eases the heavy burden placed on aging transformers on site.Our 20kvar 400V wall-mounted Static Var Generator serves as a dedicated power quality device for water treatment facilities. Utilising a voltage-type PWM inverter and high-speed IGBT power modules, it can continuously output or absorb reactive current to stabilise grid voltage and maintain the power factor close to 1.Compared with conventional fixed capacitor banks and TSC compensation systems, the SVG dynamically adjusts its output according to real-time load changes to achieve precise matching. For water treatment plants, this cuts energy waste, avoids power factor penalties from power companies, and extends the service life of transformers, motors and cables.

Technical Mechanism & Core Innovations :

• This Static Var Generator is built on voltage-source inverter architecture.
• Real-time sampling of load current is performed, and the DSP + FPGA controller calculates the required reactive current.
• High-frequency PWM modulation drives the IGBT bridge to generate compensation current, which is phase-opposite to the reactive portion of the load.
• Reactive power regulation relies on ADALINE adaptive linear neural network algorithm. It supports autonomous self-learning of site parameters, removing the need for manual parameter configuration and significantly lowering commissioning difficulty.
• Key performance indicators include dynamic response faster than 5ms, harmonic filtering covering 2nd~50th orders, and compensated power factor exceeding 0.98.
• Since grid regulation is realised by active current injection rather than capacitor switching, resonance risks are eliminated.
• It maintains good compatibility with solar inverters, variable frequency drives and various non-linear loads.

Core Advantages :

1. Model ND-SVG-20-400 SVG features modular cabinet construction and premium industrial components.
2. PWM speed-variable fans automatically adjust cooling capacity based on real-time output, restricting noise ≤55 dB and controlling active power loss below 2.5%.
3. Powerful EMI resistance enables uninterrupted operation in challenging grid environments.
4. Refined internal circuit arrangement improves energy efficiency and extends the total equipment lifespan.
5. The all-in-one compensation module performs reactive power correction, harmonic suppression and three-phase imbalance regulation concurrently, tackling various power quality problems at the same time.
6. Selectable HMI: built-in or external touch screen to suit different operating habits.
7. Energy saving: low self-consumption and low noise reduce running cost.
8. Flexible installation method: Supports wall mounting, vertical installation and rack mounting, suitable for various distribution spaces.
9. Global after-sales: 24-hour remote support, spare parts supply and on-line technical training.
