ABB launched the efficient and economical ACS2000 general-purpose medium-voltage VFD (Variable-frequency Drive)

As the latest member of ABB's medium-voltage AC VFD (Variable-frequency Drive) series, ACS2000VFD (Variable-frequency Drive) is the world's first voltage source medium-voltage transformer without a rectifier transformer. It is simple, efficient and low-cost The characteristics represent the latest trend of VFD (Variable-frequency Drive) technology and market.

ACS 2000VFD (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 reactive power compensation, and convenient installation and commissioning, providing a wide range of applications Provides reliable motor control. This medium-voltage VFD (Variable-frequency Drive) with a rated capacity of 400-1,000 kVA and a voltage of 6-6.9 kV is widely used in pumps, fans, conveyor belts, Mills and mine hoists and other fields.

Mr. Niko Railo from the medium-voltage transmission department of Beijing ABB Electric Drive System Co., Ltd. said that the introduction of ACS 2000 medium-voltage VFD (Variable-frequency Drive) made up for ABB’s shortcomings in small power, enabling ABB to Offers a full range of medium voltage transmission products. More importantly, although the demand in North America and Europe is mainly based on 3kV and 4kV products, 6kV is the most important application market in China. 3-10kV small and medium power VFD (Variable-frequency Drive) accounts for half of the Chinese VFD (Variable-frequency Drive) market, while 6kV occupies 60% of the small and medium power VFD (Variable-frequency Drive) market capacity, and the market demand is huge. At present, this VFD (Variable-frequency Drive) has been produced in Beijing, which further reduces the cost and shortens the response time of delivery and after-sales service.

Flexibility of grid connection

According to the voltage level of the user's power grid, the user can flexibly choose to operate with or without a transformer. When using a power grid with a voltage level of 6~6.9kV, it is not necessary to have a transformer, and a power grid with other voltage levels needs to be connected to a conventional double-winding oil-type or dry-type input isolation transformer.

Active Front End (AFE) technology for lower harmonics and lower power consumption

Integrates Active Front End (AFE) technology to minimize grid-side harmonics without the use of expensive, dedicated transformers; allows four-quadrant operation, feeding braking energy back to the grid; provides reactive power compensation , to maintain a smooth grid voltage.

DTC and VSI technology provide high reliability and best control performance

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.

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

The ACS 2000VFD (Variable-frequency Drive) control platform uses ABB's highly acclaimed DTC (Direct Torque Technology) platform, which can provide the maximum torque and speed performance and the lowest loss among medium-voltage AC VFD (Variable-frequency Drive). VFD (Variable-frequency Drive) control is quick and smooth under all conditions.

Humanized design simplifies installation, commissioning and operation and maintenance

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.

Significantly lower total life cycle costs

Without the use of transformers, direct grid connection applications can significantly reduce investment costs; the use of IGBT active rectification minimizes user system losses and reduces operating costs; as the most compact VFD (Variable-frequency Drive) in the world, ACS 2000 can save land. Save investment while saving space; adopt modular design, common spare parts, save operation and maintenance costs.
