1756-CPR2 Redundant power module

1、 Basic parameters
Power type: A DC power module designed for redundancy, typically inputting a specific range of DC voltage and outputting a stable DC voltage for use in the ControlLogix system.
Output power: It has a certain output power to meet the power requirements of the connected ControlLogix modules and devices. The specific output power value may vary depending on different models and configurations.
Size and weight: with standard industrial module dimensions for installation in control cabinets. Relatively moderate weight, easy to handle and install.
2、 Performance characteristics
High reliability:
Redundancy design is one of its important features. When one power module fails, another power module can seamlessly take over, ensuring the continuous operation of the system and greatly improving its reliability.
Using high-quality electronic components and advanced manufacturing processes, it has good stability and anti-interference ability, and can work reliably in harsh industrial environments.
High efficiency:
Has high conversion efficiency, can effectively convert input electrical energy into stable DC voltage output, reduce energy loss, and lower operating costs.
The output voltage is stable with small ripple, providing high-quality power supply for the ControlLogix system, ensuring system performance and stability.
Easy to install and maintain:
The installation method is simple and can usually be directly inserted into the power slot of the ControlLogix chassis, without the need for complex wiring and installation processes.
Equipped with status indicator lights, it can intuitively display the working status of the power module, making it easy for maintenance personnel to diagnose and maintain faults.
Strong compatibility:
It has good compatibility with other modules and devices in the ControlLogix series and can be seamlessly integrated into the ControlLogix control system, providing reliable power assurance for the system.
3、 Application scenarios
Industrial automation production line: In industrial automation production lines that require high production continuity, the 1756-CPR2 redundant power module can ensure the stable operation of the control system, avoid production interruptions caused by power failures, and improve production efficiency and product quality.
Critical task systems: In some critical task systems, such as power, petrochemicals, transportation, etc., system reliability is crucial. The 1756-CPR2 redundant power module can provide highly reliable power supply for these systems, ensuring their safe and stable operation.
Application in harsh environments: In harsh environments such as high temperature, high humidity, and strong vibration, ordinary power modules may be prone to malfunction. The 1756-CPR2 redundant power module has good anti-interference ability and stability, which can adapt to these harsh environments and provide reliable power guarantee for the control system.

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.
