2010-01-21 - The ACS2000 air-cooled general purpose AC drive is designed for high reliability, easy installation and fast commissioning, reducing the total cost of ownership.
ABB, the leading power and automation technology group announces the Australian launch of the new ACS2000 air-cooled general purpose AC drive. The ACS 2000 is specifically targeted at fan, pump, compressor and other common applications in industries such as water, cement, minerals and mining, metals, oil and gas, pulp and paper, power generation and chemical.
The drive is rated from 400 to 1,000 kVA in voltages up to 6.9 kV and is ideal for applications that do not require an engineered drive. The ACS 2000 is packed with innovative technology to meet industries challenges, such as the need for flexible line supply connections, lower harmonics, reduced energy consumption, static VAR compensation and easy installation and commissioning.
Flexible line supply connections
Depending on the preference or the existing installation, the ACS 2000 can be used without an input isolation transformer, thereby allowing a direct connection to the line supply (direct-to-line), or it can be connected to an input isolation transformer.
With the direct-to-line arrangement, the user benefits from lower investment costs, as eliminating the transformer avoids a major capital outlay. The ACS 2000 also benefits from compact size and lighter weight compared to a drive requiring a transformer, as well as lower transportation costs and needs less space in the electrical room. Such compact size means the ACS 2000 can be retrofitted to control the speed of standard induction motors via a direct connection to a 6.0 – 6.9 kV line supply.
For applications where a voltage-matching input transformer is needed or galvanic isolation from the power supply is required, the ACS 2000 can be connected to a conventional two-winding oil or dry-type input isolation transformer.
Lower harmonics
With the integration of an Active Front End (AFE), line side harmonics are minimized without the use of expensive, specialized transformers and with the added benefit of four-quadrant operation and reactive power compensation.
The AFE provides a low harmonic signature which meets the requirements for current and voltage harmonic distortion stipulated in various standards. This avoids the need for harmonics analysis or the installation of network filters.
Reduced energy consumption
For minimal energy consumption, the AFE enables four-quadrant operation which feeds back braking energy into the line supply.
Reactive power compensation
The AFE can also provide reactive power (VAR) compensation. With static VAR compensation, a smooth network voltage profile can be maintained and reactive power penalties can be avoided.
Easy installation, commissioning, operation and maintenance
The direct-to-line technology results in quick and easy installation and commissioning as there is no transformer involved. Installing a medium voltage AC drive is easier through ABB’s “three in – three out” cabling concept. Simply disconnect the direct-on-line cable; connect the drive; and connect the drive to the motor.
The design of the ACS 2000, with its withdrawable phase modules, allows easy front access to all drive components and provides quick replacement resulting in industry leading Mean Time To Repair (MTTR).
High reliability
The drive is designed for extremely high reliability, achieved through the use of proven technologies such as multilevel Voltage Source Inverter (VSI) topology; established high-voltage IGBT power semiconductors and Direct Torque Control (DTC) motor control platform. These technologies increase reliability, extend Mean Time Between Failure (MTBF) and improve availability.
The heritage of ABB’s VSI topology, along with a patented IGBT-based multilevel design, provides near sinusoidal current and voltage waveforms making the drive compatible for use with standard motors and cables.
The ACS 2000’s drive control platform uses ABB’s award-winning DTC, resulting in the highest torque and speed performance as well as the lowest losses ever achieved in medium voltage AC drives. Control of the drive is immediate and smooth under all conditions.
Lower total cost of ownership
Flexible line supply connections, lower harmonics, reduced energy consumption, ease of installation and commissioning and high reliability, combine to give the ACS 2000 an extremely low total cost of ownership over the life cycle of the drive.
