Efficient and dynamic: Why the PQE SVG outperforms traditional reactive power compensation with capacitors
In many industrial and commercial applications, stable power quality is a crucial success factor – not only for the reliable operation of machines, but also for long-term reduction of operating costs. Conventional reactive power compensation systems with capacitors are increasingly reaching their limits.
With the PQE SVG (Static Var Generator) PQ ENGINEERING offers a modern, powerful and flexible solution for electronic reactive power compensation. Especially in the ready-to-connect Cabinet solution SVG C-TV The system combines innovative technology with easy integration – ideal for new systems and retrofits.
What is the PQE SVG?
The Static Var Generator (SVG) is a static reactive power compensator that compensates both capacitive and inductive reactive power fully automatic and stepless In contrast to conventional capacitor systems, the control is carried out dynamic, in real time and without wearing parts such as contactors or thyristors.
The SVG continuously measures the current flow and actively compensates for unwanted reactive currents. This not only improves the grid quality but also the overall energy efficiency of the plant. In addition to the direct savings on reactive power charges, the SVG also ensures longer service life of electrical consumers through voltage stability and reduction of harmonic load.
Advantages of the PQE SVG over conventional capacitor systems
1. Fast response in milliseconds
The SVG reacts to load changes in real time and immediately provides the required reactive power – in contrast to step-based capacitor systems, which often switch with a delay or imprecisely.
2. Improved network quality
Active control not only compensates for reactive power, but also reduces voltage drops, phase asymmetries, and, to some extent, harmonics. This is particularly relevant for sensitive machines, control systems, or converter technology.
3. No over- or undercompensation
Conventional compensation systems tend to be incorrectly dimensioned when load fluctuations occur. The SVG, on the other hand, works load-dependent, avoids resonance effects and compensates both for power consumption and feed-in – e.g. through PV systems or frequency converters.
4. Low-maintenance and durable
With no wearing parts such as capacitors, contactors, or fans (depending on the model), maintenance requirements are significantly reduced. The SVG is designed for continuous operation – without regular component replacement.
5. Space-saving cabinet solution SVG C-TV
With the pre-assembled, modular control cabinet, the SVG is ready-to-connect system Ready to use – ideal for new construction projects, renovations or as a retrofit solution in confined spaces.
6. Energy efficiency & economical operation
Reactive power generation through electronic compensation reduces internal grid losses and minimizes reactive power costs in the electricity tariff – a real economic advantage in times of rising energy costs and tightening grid requirements.
7. Hybrid capable: SVG + active filter (AHF)
The SVG C-TV cabinet solution can also be implemented as a hybrid solution: SVG and active filter modules (AHF) can be combined in one system. This allows for reactive power compensation as well as harmonic reduction – ideal for demanding industrial networks with non-linear consumers.
8. Flexible use in any industry
Whether it's an office building, hotel, hospital, industrial hall, or manufacturing facility – the PQE SVG is scalable and adaptable. Depending on the network size and load profile, we will put together the right solution – including network analysis and ROI calculations upon request.
Conclusion
With the PQE SVG Companies have access to a powerful, low-maintenance, and economically attractive solution to meet the challenges of modern power grids. Electronic reactive power compensation outperforms traditional capacitor solutions in Response time, precision, durability and efficiency – making it the future-proof choice for anyone who doesn’t want to leave network quality to chance.
The prefabricated Cabinet solution SVG C-TV completes the overall package: minimal installation effort, maximum effect.
