Why power factor has to be taken into account when specifying a UPS

When specifying a new UPS, its power rating must be well matched to the job in hand. If the UPS cannot handle the real power and the reactive power consumed by the load an overload situation will quickly develop that could lead to UPS damage or outage and the critical load becoming unprotected.

However, picking the correct power rating is not as straightforward as it may seem as, for most applications, the aspect of power factor and load profile will have to be taken into consideration.

To find out how this approach can be taken in practice, we highly recommend the ABB White Paper “Power factor and the uninterruptible power supply” by Elina Hermungen.

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“.
