ACS 6000

ACS 6000 - The world’s most successful MV multidrive ABB’s ACS 6000 medium voltage drive provides the optimum solution for applications where high power and maximum reliability is required. Since its introduction, the ACS 6000 has gained an excellent reputation for high quality and reliability. As a result ABB has worldwide the largest installed base of medium voltage multidrives incorporating the latest technology. ABB’s ACS 6000 is a modular drive designed for the most demanding single-motor or multi-motor applications.

The optimum configuration for each application is reached by combining the modules with minimum engineering effort resulting in lower investment costs and a smaller footprint. It is available with five sizes of inverter modules (3, 5, 7, 9 and 11 MVA). • Average annual increase of more than 100 % since product launch • Largest installed base of medium voltage multidrives worldwide 10000 8000 Several motors can be linked to the ACS 6000 via the common DC bus, enabling multi-machine operation with only one multidrive converter. A multidrive, common DC bus converter principle offers a solution with optimum efficiency.

Key features The ACS 6000 medium voltage drive for speed and torque control of 3 – 27 MW induction or synchronous motors is a member of the ABB AC drives product family. It offers a number of unique key features. Powerful performance Fast and accurate process control in combination with low energy consumption results in top performance. The motor control platform of the ACS 6000 is based on ABB’s award-winning Direct Torque Control (DTC) technology. DTC provides the highest torque and speed performance ever achieved in medium voltage drives. As a result, control of the drive is immediate and smooth under all conditions.

Key product features • DTC control platform for exceptionally high torque and speed performance • IGCT power semiconductors for highest reliability and efficiency • Line Supply Unit (LSU) for two-quadrant operation with a constant power factor of 0.96 over the whole speed range High efficiency and reliability The ACS 6000 uses a revolutionary power semiconductor switching device known as IGCT (Integrated Gate Commutated Thyristor) researched and designed by ABB. The use of IGCTs results in a less complex, more efficient and reliable high-power medium voltage drive, minimizing operating and maintenance costs.

• Active Rectifier Unit (ARU) for four-quadrant operation and reduced harmonics, adjustable power factor • Common DC bus for single and multiple-motor operation and energy recuperation • Modular design for optimum configurations ARU Active Rectifier Unit CBU Capacitor Bank Unit INU Inverter Unit LSU Line Supply Unit 12-pulse LSU single drive 6-pulse ARU single drive The ACS 6000 inverter topology ABB 4 - ACS 6000

High availability Maximum reliability and short repair time results in a drive with high availability. • High power and maximum reliability • Smooth torque over the entire speed range • Applications operate at optimum efficiency • Compact and high power density • Low noise and vibration levels • Minimized energy consumption with common DC bus • Regeneration of rotating energy Optimized energy flow The common DC bus allows several motors to be connected to the same DC bus, providing an optimized energy flow. The braking energy generated in one motor can be transferred to other inverters via the common DC bus without power consumption from the supply network.

Due to the near unity power factor throughout the whole speed range the energy efficiency is optimal. Flexible Optimum configuration The modular design of the ACS 6000 allows the optimum configuration of any drive system. Each configuration, consisting of well-proven and certified modules, exactly fits the customer’s requirements. Smooth system integration The ACS 6000 integrates easily into the industrial environment because it can be optimally configured for single-motor and multi-motor applications without additional control equipment. The high power density and compact design and the drive’s communication abilities minimize the overall installation and operational costs.

Optimized energy flow with common DC bus e.g. cold reversing steel mill The drive can be connected to the network through one or several transformers depending on power and harmonics requirements. Even a transformerless solution is available for certain applications. ABB ACS 6000 - 5 ACS 6000 advantages
