Static Var Generator SVG 15kvar for Commercial Building

Product Overview

For commercial buildings this compact wall-mounted unit corrects the power factor of HVAC, lifts and lighting loads, lowering the kVA demand charge and cutting the monthly electricity bill.

The Static Var Generator SVG 15kvar 400V Compact Wall Mounted Power Factor Correction for Commercial Building is a professional power quality device engineered for commercial buildings and HVAC systems. As a modern Static Var Generator, it employs a voltage-source PWM inverter with high-speed IGBT power modules to inject or absorb reactive current continuously, keeping the grid voltage stable and the power factor close to unity. Unlike fixed capacitor banks or TSC systems, this Static Var Generator adjusts its output in real time, so the compensation always matches the actual load. For commercial buildings and HVAC systems, this means lower energy losses, fewer electricity penalties and a longer service life for transformers, motors and cables. Its rated capacity of 15kVAR at AC 400V makes this Static Var Generator a practical fit for medium and large industrial grids, and every SVG unit we produce is tested under full load in our own workshop before shipment.

Working Principle and Core Technology

The Static Var Generator works on a voltage-source inverter principle. It continuously samples the load current, calculates the required reactive current with a DSP + FPGA controller, and then drives an IGBT bridge through high-frequency PWM modulation to generate a compensating current that is opposite in phase to the reactive component of the load. This Static Var Generator adopts an ADALINE adaptive linear neural network algorithm for reactive power regulation, which supports autonomous on-site parameter self-learning, so engineers do not need to configure parameters manually and field commissioning becomes far simpler. The outcome is a Static Var Generator with a dynamic response below 5 milliseconds, harmonic suppression from the 2nd to the 50th order, and a compensated power factor above 0.99. Because it corrects the grid through active current injection instead of capacitor switching, it introduces no resonance hazard and stays compatible with solar inverters, variable-frequency drives and other non-linear loads.

Key Features

Each ND-SVG-15-400 Static Var Generator combines a modular cabinet structure with industrial-grade components. The unit is equipped with PWM variable-speed fans that adjust cooling according to the real-time output power, keeping noise below 55 dB and system active power loss under 2.5 percent. Robust anti-electromagnetic interference capability lets this Static Var Generator operate continuously in complex grid environments, while the optimised internal circuit layout maximises energy savings and extends the overall service life of the equipment. The versatile integrated compensation engine of this Static Var Generator can handle reactive power offset, harmonic filtering and three-phase load imbalance correction at the same time.

FAQ

Q1: What harmonic range can your Static Var Generator suppress?
A1: Our SVG covers the 2nd to the 50th harmonics, fully eliminating distortion generated by inverters, motors and other non-linear loads.

Q2: How fast does the Static Var Generator respond to load changes?
A2: The dynamic response is less than 5 milliseconds, giving instant reactive power compensation that stabilises fluctuating grid voltage.

Q3: Can the Static Var Generator reduce a building monthly electricity bill?
A3: Yes. By raising the power factor above 0.99, the Static Var Generator lowers the kVA demand charge and reduces line losses, which is reflected in the monthly electricity bill.

Q4: Is the Static Var Generator expandable for a later capacity upgrade?
A4: Yes. The modular parallel design lets several Static Var Generator units work together, so you can expand the total compensation capacity on demand without replacing existing equipment.
