Product Category: The ABB ACS6000 is a medium-voltage frequency converter series, designed specifically for high-power industrial applications (3000-36000kW), and widely used in wind power, marine propulsion, metallurgy, mining, chemical, and other fields. Its input/output units support modular configuration and are compatible with multi-pulse rectification (6/12/24 pulses) and active rectification technologies.
Electrical Characteristics:
Input Configuration: 6-, 12-, or 24-pulse diode rectifier (input voltage 3300V/1725V) or 6-, 12-, or 18-pulse active rectifier (input voltage 3160V). Input voltage fluctuation ±10% (no derating) or +15/-30% (derating output), frequency 50/60Hz ±5%.
Output Characteristics: Output voltage 2.3kV/3.3kV, frequency 0-75Hz, supports induction motors, synchronous motors, and permanent magnet synchronous motors; efficiency >98%, power factor >0.95 (diode rectification)/1.0 (active rectification).
Cooling System: Water-cooled closed-loop design, cooling water temperature 5-32°C, pressure 200-500kPa, integrated heat exchanger bypass valve to ensure stable temperature (-10°C to +45°C environmental adaptability).
Key Components:
Input/Output Units: Includes rectifier unit (LSU, such as a 12-pulse diode rectifier), inverter unit (INU, 6-pulse self-commutating inverter), capacitor bank (CBU), control unit (COU integrated into the terminal unit TEU), water-cooled unit (WCU), and excitation unit (EXU, dedicated to synchronous motors).
Modular Design: Supports power module combinations (3/5/7/9/11MVA inverter modules), enabling multi-motor coordinated or redundant drive through parallel DC bus connection, such as twin drives for dual-winding motors and side-pusher configurations sharing a DC bus.
Physical Structure and Protection:
Protection rating IP32/IP42/IP54, cabinet height 2200mm (2500mm including cooling fan), depth 1040mm, noise <75dBA.
Environmental Adaptability: Altitude 0-2000 meters (derating required for higher altitudes), temperature 0-40°C (derating required for higher temperatures).
Core Functions and Technical Highlights:
Control and Communication:
The controller adopts the ABB AC 800PEC series, supporting protocols such as Profibus DP, Modbus TCP, EtherCat, and CANopen, and can be integrated into control systems such as Mark VI.
Equipped with Direct Torque Control (DTC) technology, it achieves maximum torque at zero speed, low torque ripple, and high dynamic response, enabling precise control without a speed encoder.
Reliability and Redundancy:
Complies with IEC 62061 SIL CL2 safety standards, featuring overvoltage/undervoltage protection, braking resistor management, and STO (Safe Torque Off) function.
Supports redundant configurations (such as dual inverters in parallel), improving system availability; modular design facilitates maintenance and expansion.
Energy Efficiency and Environmental Protection:
Efficiency >98%, harmonics comply with IEC 61000-2-4 and IEEE 519 standards, reducing energy consumption and carbon emissions.
Soft-start function reduces mechanical stress and extends equipment life; low-maintenance design reduces downtime.
Power Semiconductors: Based on IGCT (Integrated Gate Commutated Thyristor) technology, combining IGBT high-speed switching and GTO high blocking voltage characteristics, reducing component count, improving efficiency and reliability, and supporting fuse-free designs.
Four-quadrant operation: The active rectifier unit (ARU) supports bidirectional energy flow, enabling regenerative braking energy recovery to the grid. The power factor is adjustable (0.8 lead to 0.8 lag), meeting the dynamic positioning and soft-start requirements of scenarios such as ships and mines.
Environmental adaptability: Complies with classification society certifications such as DNV, Lloyd’s, and ABS. It withstands high altitudes (0-2000 meters, derating available), wide temperature ranges, vibration, and salt spray environments. It supports redundant main propulsion configurations (e.g., dual inverter power supply) to ensure continuous operation under fault conditions.
Application scenarios and cases:
Typical industries:
Wind power: Adaptable to 4-12MW wind turbines, supports nacelle/tower installation, and meets grid harmonic requirements below the 29th order.
Marine: Propulsion systems, pumps, and compressor drives, complying with classification society certifications such as DNV-GL, ABS, and CCS, supporting dynamic positioning and redundant configurations.
Metallurgy/Mining: Drives for rolling mills, hoists, crushers, and ball mills, resistant to high vibration, shock, and wide temperature environments.
Chemical/Petroleum: Control of pumps, compressors, extruders, and fans, meeting explosion-proof and corrosion-resistant requirements.
Special Applications:
High-precision control scenarios such as test benches, wind tunnels, power grid simulators, and shore power supplies.
Compatibility and Expandability
System Integration:
Works seamlessly with other ABB products (such as ACS880 and AC800PEC), and supports communication with PLC/DCS systems from brands such as GE and Siemens.
Compatible with industry standard protocols (such as Modbus TCP and EtherNet/IP), facilitating integration into existing automation architectures.
Expansion Options:
Modular expansion via VME bus or rack mounting (e.g., braking resistors, feedback line shielding, diagnostic modules).
Supports customized configurations (e.g., transformerless design, multi-motor drives, redundant power supply modules).
