The role of the static switch in supplying continuous power under all conditions

Uninterruptible Power Supplies (UPS) support critical loads by using stored energy during mains power blackouts. But they must also offer protection from electrical noise, spikes and surges as well as overloads and possibly even failures within themselves.

In a recently published article, Alan Luscombe, Director at Uninterruptible Power Supplies Ltd., a Kohler company, explores the role of static switches and their contribution to UPS protection, especially with systems that have a modular topology.

His conclusion:

„Modern UPS systems are seldom single-channel architectures; modular implementations offer many advantages. However, these installations must be internally synchronised to function successfully, with all modules either on inverter or on bypass. The use of one static switch per module is favoured, to avoid a single point of failure.

Today’s UPS systems, especially those that use modular technology, are flexible and easily scalable while protecting their critical load from many different threat types. Static switches play a key role in assuring this resilient performance.“

Case study: UPS systems by ABB protect a leading brewery’s production, filling and logistics center

The Krombacher brewery is one of the leading pre-mium breweries in Germany. Installed in autumn 2015, three DPA UPScale ST UPS systems by ABB protect the company’s production, filling and logistics center in Krombach.

In 2015, the brewery delivered an all-time high in terms of output and sales revenues and sold 4.26 million hectoliters of Krombacher Pils alone, their flagship product. In order to ensure a continuous production and logistics of such large quantities, the supply of uninterruptible, clean i.e. undisturbed power has to provided.

With the decision for the replacement of the aged UPS installation with state-of-the-art UPScale ST systems in 2015, the brewery made the step towards modular UPS technology.

One important argument for the ABB solution was the decentralized parallel architecture (DPA) of the DPA UPScale ST modules. Each system consists of autonomous UPS modules containing the complete hardware and software required for the operation of the overall system. In the worst-case event when one UPS module fails, the overall system continues operation with the capacity of one module less (N+1-redundancy).

“In regard to fail-safety, the concept of a modular exchange was the crucial criteria. Using 10 or 20 kVA modules, each system featured good scalability according to the respective power requirements“, Timo Kleinsorge , from Krombacher Brauer states.

Timo Kleinsorge sees the benefits of the new solution in an increased flexibility, availability and cost-effectiveness: “The systems are optimally designed for the required performance and not over-dimensioned. Through modular technology, we can easily expand the systems without having to purchase a new UPS system. Furthermore, the N+1-concept provides maximum availability“.

Opportunity in Global DCIM Market to Near US$ 3 billion by 2024 

According to a new report by Transparency Market Research, the opportunity in the global DCIM market stood at US$ 529.5 mn in 2015 and is likely to be worth US$ 2859.2 mn by 2024, registering a strong CAGR of 21.1% from 2016 to 2024.

Transparency Market Research has observed that the rivalry among existing companies in the DCIM market is presently high as leading players are acquiring smaller enterprises to gain market share. New product development, business partnerships, and diversification are also key strategies adopted by the leading companies to remain competitive.

“The surging usage of internet across the globe has resulted in the generation of massive amounts of data, which in turn, has driven the growth of data centers,” states the author of the study. Most data centers operate round the clock and consume significant amounts of energy for lighting, cooling, heating, and IT equipment. “Data centers today are prompted to curb energy consumption and optimize efficiency and DCIM solutions have fulfilled this very demand. This is one of the key factors fueling the data center infrastructure management market,” the analyst says.

The market is also anticipated to be driven by the rise in government regulations pertaining to carbon emissions. “Governments around the world have been paying increased attention to the alarming rise in carbon emissions and are enforcing regulations to drive companies to build and use green data centers,” the analyst comments. The DCIM market is projected to benefit from this emerging trend in the coming years.

On the down side, the lack of expertise and awareness regarding the benefits of DCIM solutions are likely to inhibit the growth of the global market. High initial investment also acts as a barrier for several small-to-medium enterprises.

The major trends shaping IT infrastructure delivery and strategy

The recently published sixth annual Uptime Institute Data Center Industry Survey provides an overview of the major trends shaping IT infrastructure delivery and strategy. It is largely focused on how enterprise IT and infrastructure is deployed and managed, both in enterprise-owned data centers and through off-premise computing models.

The results show that enterprise IT budgets are shrinking. This also has an impact on colocation providers, that had experienced a massive growth for the last five years, trying to keep up with the demand. But the forces shrinking enterprise IT deployments are now impacting the capital project cycle, even for colocation providers.

Matt Stansberry, Director of Content and Publications for the Uptime Institute and author of the report on the survey results, also provides a clear view on the status of efforts for better data center efficiency:

„In many cases, IT infrastructure teams are still relying on the least meaningful metrics to drive efficincy. The majority of IT departments are positioning total power consumption, LEED certifications, and total data center power usage as primary indications of efficient stewardship of environmental and corporate resources.

Infrastructure leaders should not co-opt the Corporate Sustainability departement to continue to perpetuate the fallacy that efficent computer room air conditioning is indicative of an efficient IT organization.“

How modular UPSs can contribute to a data center’s DCIM strategy

Data center infrastructure management (DCIM) is gaining in popularity as a solution, and often viewed as one of today’s most significant areas of green computing. DCIM tools – like ABB’s Decathlon for Data Centers – monitor, measure, manage and/or control data center utilization and energy consumption of all IT-related equipment.

In a recently published article on Datacenter Dynamics UPS Ltd’s Alan Luscombe points out how bringing the UPS into the DCIM environment provides significant benefits in securing data center availability and efficiency.

“This relationship works best if DCIM/UPS communication is two-way”, he writes. “The DCIM software monitors the UPS status, and can make tactical or strategic decisions that drive changes to the UPS’s operation, maintenance plan or configuration.”

Luscombe is also convinced that the UPS topology plays a critical role in setting up a DCIM strategy that contributes to efficiency and availability. He recommends modular design:

“As data center loads become ever larger, more complex and changeable, DCIM offers a logical management solution while achieving greener, more highly-available data centers. UPSs with the right topology, software and communications capabilities can contribute significantly to these objectives.”

Recommended reading: „Making your power infrastructure elastic“

Data centers can be more flexible with an elastic power infrastructure, says Dave Sterlace, global head of data center technology at ABB in a recent interview with DatacenterDynamics. His point of view is: The current emphasis on hardware redundancy doesn’t always do the job.

Based on the software redundancy that’s at the core of the cloud, and the new thinking around cooling, Sterlace predicts that the next few years will be exciting in terms of new ways of thinking on the facilities side.

From the article:

One approach would be to ditch today’s hard-wired control with its thousands of distinct point-to-point connections, and replace it with a communications platform based on open standards and tried-and-tested Ethernet technology – long used in computer networks.

“[Such an approach] reduces points of failure, makes troubleshooting faster and easier, and reduces commissioning time as well,” said Sterlace. “Additionally, these new open protocols save you from buying into one manufacturer’s version of control and communications. What if they decide to change direction or discontinue?”

Another approach would be to swap out the traditional modular UPS for one containing integrated components and greater intelligence.

“The traditional approach might be to add capacity with a modular UPS, which builds out in 500kW blocks, and modify the upstream and downstream switchgear and PDUs [power distribution units] to match, usually by taking portions of switchgear out of service, working on one side, then the other,” explained Sterlace.

An elastic approach helps to reduce complexity and simplify upgrades, reducing deployment and commissioning time, says Sterlace, while the built-in intelligence makes it possible to tweak power and control schemes via software choices. Moreover, any difference in capital cost is outweighed by labor savings in commission and operations, he said, citing projects done by ABB.
