4、 Application Fields
1326AS-B440G-21-A brushless servo motor is widely used in various industrial automation and robot control systems, including but not limited to manufacturing, automated production lines, packaging machinery, printing machinery, textile machinery and other fields. Its high precision, high response speed, and high reliability make it an ideal choice for achieving precise position control, speed control, and torque control.

As a pioneer in technology, ABB has received an order from Transpower New Zealand to upgrade its high-voltage direct current (HVDC) transmission lines, which interconnect the transmission networks of the North and South Islands.

It is reported that this high-voltage direct current transmission line connecting the North Island and South Island of New Zealand is an important component of the country’s power grid system and also the power balance system between South Africa. ABB’s Ability MACH control system, as the brain or nerve center of the link, will become a key component of the upgrade.

It is reported that the population of the North Island of New Zealand is more than three times that of the South Island, and in addition to its picturesque scenery, it also provides a large amount of hydroelectric power. Therefore, the demand for electricity in the North Island has greatly increased and relies on the power supply in the South Island. The north-south high-voltage direct current transmission interconnection line, which is over 600 kilometers long, can efficiently transmit clean electricity to high demand areas. The line also plays an important role in the New Zealand electricity market by allowing electricity trading between two islands.

ABB has a historic involvement in this project. The first New Zealand HVDC transmission system was built by ABB (formerly ASEA) in 1965, which was also one of the world’s first HVDC transmission systems at that time. It was originally a bipolar 600 megawatt (MW) link with a mercury arc valve, until 1992 when the original equipment was connected in parallel to a single pole and ABB collaborated with it to debug a new thyristor pole, increasing the capacity to 1040 MW.

It is reported that this upgrade includes the upgrade of Valve 2, which is composed of electrodes, optical fibers, and valve control units based on the latest ABB Ability MACH control system. The upgrade will be completed in 2020, and its implementation will minimize the impact on the power grid and electricity trading market.

This upgrade will improve the reliability and availability of the power grid, thereby enhancing power safety and bringing clean energy to consumers, “said Claudio Facchin, President of ABB’s Power Grid Division.” This project reaffirms our strategic focus on services and commitment to integrating renewable energy, as well as the role of digital technology based on ABB’s capabilities, and consolidates our leading position in HVDC technology, becoming the preferred partner for achieving a stronger, smarter, and more environmentally friendly power grid

ABB pioneered high-voltage direct current transmission technology 60 years ago and has obtained approximately 120 high-voltage direct current transmission projects with a total installed capacity of over 130000 megawatts, accounting for about half of the global installation base.
