SVG for Commercial Buildings and Power Factor Correction

SVG for commercial buildings is used to improve Power Factor correction, reduce reactive power, and support voltage stability. Modern commercial buildings use HVAC systems, elevators, pumps, lighting, UPS systems, and office equipment. These loads change throughout the day.

When the load changes, the electrical system can become less efficient. Poor power factor increases current, adds heat, wastes capacity, and may raise electricity costs. A Static Var Generator helps correct this problem in real time.

For many commercial buildings, SVG is a better solution than a traditional capacitor bank. It responds faster, works more accurately, and supports changing loads.

What Power Factor Means in Commercial Buildings

Power factor shows how efficiently a building uses electrical power. In simple terms, it compares real power and apparent power.

Real power does useful work. It runs chillers, fans, pumps, elevators, lights, and office equipment.

Apparent power is the total power supplied by the electrical system. It includes real power and reactive power.

Reactive power does not do useful work, but many loads still need it. Motors, compressors, pumps, and HVAC systems all create reactive power demand.

When reactive power is too high, the phase angle between voltage and current increases. This causes poor power factor. The building then draws more current to do the same work.

That extra current creates more heat in transformers, cables, breakers, and switchgear.

Common Power Quality Problems in Commercial Buildings

Commercial buildings have changing electrical loads. In the morning, HVAC systems start. Elevators run more often. Lighting and office equipment turn on. During peak hours, pumps, chillers, fans, and UPS systems add more demand.

This creates several problems:
