Static Var Generators are a revolutionary new standard in reactive energy compensation. When the load is generating inductive or capacitive current, it makes the load current lag or leads the voltage. This article explains why Static Var Generator is the chosen solution for reactive compensation.

Why Choose SVG?

A low power factor means you are drawing more current than you need. The Australian Energy Regulator allows electricity retailers to penalise businesses for the extra demand on the electricity grid. If your most recent power bill has a charge for kVA, then your Power Factor is probably inflating your bill.

Poor Power Factor can be improved by installing Power Factor Correction (PFC) equipment to correct your energy supply inefficiencies, reducing the total current and apparent power (KVA) demand on the electricity network and bring the power factor close to 1 (unity).

Quality Energy Static Var Generator

Quality Energy's Static Var Generator (SVG) is an entirely new approach to power factor correction. SVG works in a similar way to an active filter: it injects a current in the opposite direction to counteract reactive power (inductive and capacitive), thus ensuring that target cosϕ is achieved at all times.

Quality Energy's range of Static Var Generators are high-performing, compact, flexible, modular and cost-effective to respond instantaneously and effectively to resolve power quality problems in low or high-voltage electric power systems.

We manufacture SVG in our factory at Moorabbin, Victoria, featuring:

• three-level topology
• ultra-compact modular design
• fast-switching frequency 25.6kHz
• low power consumption  ≤2.5%
• leading dissipation technology
• continuous Power Factor Correction
• precise Power Factor maintain -1.0  ≤ Cos Φ ≤ 1.0
• both capacitive and inductive control
• no over or under-compensation
• hybrid Power Factor Correction
• three-phase load balance
• low noise

Power Factor Correction is not a one-size-fits-all solution. Quality Energy has been Australia's leading Power Factor Correction specialist for close to 35 years now. We supply custom Low Voltage (LV) and High Voltage (HV) Power Factor Correction solutions Australia-wide for industrial and commercial settings. We are experts in managing projects for both LV and HV compensation. Our solutions are manufactured in our Melbourne-based facility using premium components, and we offer service and commissioning capability to our client's sites.

Hybrid AHF-SVG Solutions

Power factor displacement and current distortion are two critical indicators of the grid power quality. However, the ever-increasing deployment of high-power converters in industrial applications causes the grid's power quality to deteriorate. Although Active Harmonic Filter (AHF) alone can address both the low power factor issue and the high current distortion issues of power quality, AHF can be an expensive solution to manage multiple power quality problems. We offer an economical hybrid solution combining the AHF and SVG features.

Main features of hybrid AHF-SVG solutions:

• harmonic mitigation, reactive power compensation and load balancing in a single solution
• single cabinet, meaning single supply and a reduction in installation costs
• up to four modules in a cabinet in any combination
• IP30 and IP54 as standard

Applications

• Industries having VFD and inverters, UPS, etc.
• Industries having textiles, paper, etc.
• Steel
• Automobile
• Data centres
• Hospitals
• Solar generation farms
• Windmills

Conclusion

Quality Energy's Static Var Generators (SVG) provide high-efficiency reactive power in a compact and high-performing cabinet, making it cost-effective to resolve power quality problems in low and high-voltage electric power settings.

Since 1989, Quality Energy is a power quality and energy efficiency solutions provider and manufacturer. Our mission is to help businesses solve the problem of ever-increasing energy costs and inconsistent, unreliable power supply.
