AVE Hybrid

Automatic Voltage Equalizer Hybrid

AVE Hybrid

AVE Hybrid is the ultimate solution to any power quality related problem. Combining the AVE technology with our active units ensures optimal power quality in your plant. The active part of the hybrid solution ensures the removal of system harmonics, load balancing, and a power factor close to
one. The AVE part mitigates fast switch transients and protects the installation against voltage surges. The unit also reduces voltage dips and its effects together with reducing zero-sequence harmonics, ensuring a clean and stable ground reference, which again will reduce the risk of control system lockups. The AVE – Hybrid gives longer equipment lifetime, higher process reliability, improved power system capacity and stability, and reduced energy losses, complying with most demanding power quality standards and grid codes.

According to a European study made by Manson & Roman Targosz, the total cost of bad power quality in Europe alone is 150B euros per year. The expenses are divided according to the diagram shown on this page.

  • 29% Transients and surges
  • 24% Voltage dips
  • 19% Short interruptions
  • 5% Harmonics
  • 11% Others
  • 12% Long interruptions

By having the AVE Hybrid installed, you can protect your plant against more than 88% of these problems and subsequent costs (AVE Hybrid AVC). Depending on the power quality situation, the hybrid solution can be delivered with either APF, SVG, ASVG or a capacitor bank in conjunction
with an APF solution.

    Here is a brief summary of the various standard hybrid models available. Other variants are also available based on what will be the optimal solution for your plant.

    AVE Hybrid SVGC

    The AVE Hybrid Static VAR Generator Capacitor is a more cost-effective solution. The cost reduction is achieved by using a capacitor bank to take the central portion of the VAr compensation. At the same time, the active filter compensates for the intermediate steps and the inductive reactive power. Also, the active filter works as a load balancer and a harmonic filter. The integrated AVE technology protects against transient voltage surges and dips together with zero-sequence harmonics. In combination with our revolutionary AVE technology, this is an all-in-one, cost-effective solution for optimized power quality and:

    • Cost-effective and fast power factor correction
    • Harmonic current and zero-sequence harmonic voltage mitigation
    • Load balancing
    • Voltage surges and dips protection

    AVE Hybrid AVC RTS/DVR

    The AVE Hybrid Active Voltage Conditioner unit combines filter technology, AVE hybrid technology, UPS technology, or voltage regulator technology into one package. The unit comes with two options in terms of blackout prevention; either an energy storage system that allows for higher power outage ride-through times (AVC RTS) or with voltage vector control for smaller voltage ride-through times (AVC DVR). The AVC DVR is a more cost-effective solution than the AVC RTS but still compensates for up to 40% voltage variation for up to 30 seconds. The RTS is based on thyristor controlled ultra-capacitor banks with superior power density, cycle life, and life-expectancy for higher ride-through capacity. Both units protect your installation from power outages, interruptions, and voltage dips, while the AVE and filter technology protect against transient voltage surges, harmonic current distortion, zero-sequence voltage harmonics, and flicker. The units also perform load balancing. The Hybrid AVC has the possibility for two operational modes (optional). During a stable power supply, it operates in power quality mode performing harmonic current mitigation, load balancing, and flicker mitigation. When a power outage or voltage sag is detected, the unit switches from power quality mode to power supply mode, securing power to the plant and preventing the effects of the voltage sag or power outage. The units are available in load capacities between 150kVA to 3000kVA, with higher ratings available on request. With AVC RTS hybrid installed, the power system can ride through power outages for up to 3 seconds as standard. The 3-second limit is based on common industry standard, but other compensating time frames are possible based on system load and capacity of the energy storage system. The unit has high efficiency due to its intelligent switchover between the operation modes and provides substantial cost savings compared to conventional technology. The AVE technology will, at all times, protect against transient voltage surges, zero-sequence harmonics, and is not affected by the operational mode. Compared to the AVC RTS, the AVC DVR is not relying on capacitors to counteract voltage sags & Swells. The lack of capacitors makes this is a more cost-effective solution, but it still compensates for up to 40% voltage variation for up to 30 seconds, which prevents the effect of sags & swells in most cases. During regular operation, the AVC DVR optimizes the output power. During a voltage sag, the AVC boosts the output voltage by altering the voltage vectors to compensate for the reduced voltage.
