ADF Power Tuning

Slide background

Power quality support for many applications

The adaptability and flexibility of ADF Active Filter technology means there are a wide variety of benefits for many types of applications. Lowered disturbances, improved energy efficiency (corresponding to lower carbon dioxide emissions), increased production stability, and lower current consumption are just some of the benefits. Advancements in today’s machinery require much more sophisticated solutions than in the past, and ADF Power Tuning is here to meet the challenge, today and in the future.

Variable Speed Drives (VSD)

The most common application for ADF Power Tuning is to compensate harmonics generated by variable speed drives (VFDs or frequency converters). VFDs bring advantages such as lower energy consumption and increased production flexibility, but come with substantially increased levels of harmonics in the grid. ADF Power Tuning is the perfect solution for mitigating VFD harmonics.

Welding

Electrical welding systems demand extremely high current during short periods. This type of electrical load causes highly fluctuating voltage levels, which in turn results in flicker. Emission of flicker levels may disturb neighboring electrical consumers (industries, residential areas) and can cause reliability problems with nearby equipment.

Furnaces

Furnaces and casting processes are some of the most energy intensive industrial production processes and are known to give rise to flicker and harmonics. ADF technology is the ideal technology to solve these problems because it reacts to and corrects such load changes very quickly.

Wind Power Systems

In many cases, wind power systems are in desolate places where the grid connection is weak. This often results in issues such as flicker, exhibit harmonics or interharmonics, and other problems. There are a large number of ADF installations in wind power applications, solving a wide range of problems. Check out the DanTysk case story for an example.

Solar Power Systems

Due to the rising demands of environmentally friendly energy sources, we are seeing an increasing demand and use of solar power systems. These systems may cause harmonics or interharmonics. In some cases, especially in weaker networks where the transformer cannot accommodate the load, resonances may be triggered by the harmonic output of the solar inverters.

Lighting

In some cases, light systems will cause harmonics that need to be mitigated in order to avoid heating of neutral conductors and disturbing nearby equipment. Depending on type, modern energy saving lamps may be more prone to causing disturbances.

UPS (Uninterruptable Power Supply) Systems

UPS systems, such as those required for data centers, connected to networks polluted with harmonics run the risk of malfunction and shortened lifetime.
