The harmonic content is reduced by up to 97 percent in comparison to a conventional drive. Typically, the total harmonic current distortion is 3%.
The typical total harmonic distortion produced by a passive filter ranges from 5 to 10 percent. Harmonics mitigation is built into the compact drive.
A low harmonic line filter and an active supply unit are part of this. The simple installation saves a lot of space, time, and money because it doesn’t need special transformers, multi-pulse arrangements, or filters from outside.
As there is less gamble of overheating with lower symphonious flows, there is compelling reason need to over-aspect hardware like transformers and links.
Even when the supply voltage is below nominal, the active supply unit of the drive is able to raise the output voltage to enable full motor voltage.
This makes sure that weak networks work reliably.Additionally, voltage drops caused by long supply or motor cables can be mitigated with this voltage boost capability.
Because of the long cables, there is no need to oversize the motor or supply transformer.An advantage over passive filter solutions is the ability to stabilize the output voltage of an ultra-low harmonic drive. With a passive filter, there is typically a voltage drop of 5% at nominal loads.
On the other hand, when there are partial loads, the voltage above the passive filter can rise by as much as 10%, which could lead to an overvoltage fault.
A power factor of one indicates that electrical energy is being used effectively in ultra-low harmonic drives.In order to make up for the low power factors of equipment that is connected to the same network, the drive provides the option to correct the network power factor.
Avoiding penalties for poor power factors imposed by utilities can be aided.System losses are reduced, and overall system efficiency is enhanced, when full motor voltage and harmonics are always at their lowest.
The Global Low Harmonic Drives market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
An ultra-low harmonic (ULH) version of ABB’s ACQ580 range of variable speed drives (VSDs), which were made for pumping purposes in the water and wastewater industry, is now available.
Although it is advantageous for water plants to use VSDs in conjunction with motors, these devices have the potential to introduce harmonics into the electrical network.
These harmonics have the potential to harm delicate electronic equipment, disrupt communication systems, and result in inaccurate readings on measurement devices.
An active supply unit and a low harmonic line filter are built into the new ABB drive to provide harmonic mitigation. Contrasted with a regular drive, the ACQ580 ULH can lessen symphonious substance down to 3% all out consonant contortion of current (THDI).
The ABB ACQ580 does not require any special equipment or external filters to address harmonics-related issues, as opposed to the conventional methods of adding filters, multipulse transformers, or over-dimensioning equipment.
Customers can access real-time information about the drive’s status and performance from any location thanks to the ACQ580’s compatibility with ABB Ability monitoring services. The drive has an IP55 protection level.
