ABB launched a new series of general-purpose medium-voltage VFD (Variable-frequency Drive)

ABB has launched a medium-voltage VFD (Variable-frequency Drive) with a rated capacity of 400 to 1,000 kV and a voltage of up to 6.9 kV, which is suitable for a wide range of applications without special engineering design. the

The air-cooled ACS 2000 VFD (Variable-frequency Drive) is specially used for fans, pumps, compressors and other public applications in cement, mining and mining, metallurgy, pulp and paper, water, electric power, chemical, oil and gas industries.

ACS 2000 VFD (Variable-frequency Drive) incorporates innovative technologies to meet industry challenges, such as the need for flexible power supply connections, lower harmonics, reduced energy consumption, static var compensation, and convenient installation and commissioning.

Flexible power supply connection

The ACS 2000 VFD (Variable-frequency Drive) may not use an input isolation transformer, depending on user choice and existing equipment, thus allowing direct connection to the power supply (direct grid connection), or it may be connected to an input isolation transformer .

In the configuration of direct grid connection, users can benefit from lower investment costs, because no transformer is needed, which can save a lot of investment. Compared with other VFDs (Variable-frequency Drives) that require transformers, the ACS 2000 VFD (Variable-frequency Drive) has a compact structure, lighter weight, lower transportation costs, and requires less space in the electrical room. Due to its compact design, the ACS 2000 for direct connection to the 6.0 - 6.9 kV grid is suitable for retrofit projects of speed-controlled standard induction motors.

In applications that require voltage matching or electrical isolation of the power supply, an input transformer is required, and the ACS 2000 VFD (Variable-frequency Drive) can be connected to a conventional double-winding oil-immersed or dry-type input isolation transformer.

lower harmonic

Integrated Active Front End (AFE) technology minimizes grid-side harmonics without using expensive, dedicated transformers, and has the added benefit of four-quadrant operation and reactive power compensation.

AFE provides the characteristics of low harmonics and meets the requirements for current and voltage harmonics in various standards. This eliminates the need for harmonic analysis or installation of line-side filters.

?Reduce energy consumption

To minimize energy consumption, the AFE allows four-quadrant operation, which feeds braking energy back to the grid.

Reactive power compensation

AFE can also provide reactive power compensation. With static var compensation, a smooth grid voltage characteristic is maintained and reactive power penalties are avoided.

Easy to install, debug, operate and maintain

The direct grid connection technology without using a transformer can make the installation and commissioning work faster and more convenient. To install a VFD (Variable-frequency Drive), use ABB's simple "three-in-three-out" wiring concept, just disconnect the cable that is directly connected to the network, connect it to the VFD (Variable-frequency Drive), and then connect the VFD (Variable-frequency Drive) -frequency Drive) can be connected to the motor.

The ACS 2000 is designed with a withdrawable phase module, which is convenient for quick replacement of all VFD (Variable-frequency Drive) components from the front, and the mean time to repair (MTTR) is an industry-leading level.

high reliability

The VFD (Variable-frequency Drive) uses the proven multi-level voltage source inverter (VSI) topology, mature high-voltage IGBT power semiconductor technology and direct torque control (DTC) motor control platform, so it has extremely High reliability, extending mean time between failures (MTBF) and increasing utilization.

ACS 2000 inherits ABB's VSI topology and adopts a patented, IGBT-based multi-level design, which provides approximately sinusoidal current and voltage waveforms, making the VFD (Variable-frequency Drive) compatible with standard motors and cables.

The ACS 2000 VFD (Variable-frequency Drive) control platform uses ABB's highly acclaimed DTC platform, which can provide the highest torque and speed performance and the lowest loss that have never been seen in medium-voltage AC VFD (Variable-frequency Drive). VFD (Variable-frequency Drive) control is quick and smooth under all conditions.

Lower total investment cost

Flexible power supply connections, lower harmonics and energy consumption, easy installation and commissioning, and higher reliability make ACS 2000 have a very low total investment cost throughout its life cycle.
