Digitizing your critical power system: simple, smart and stable

In my last post, I talked about the difficulties faced by facility teams in keeping critical power facilities running safety, reliably, efficiently, and compliant with regulations. We looked at the many hidden risks that make these goals even more challenging. A fully digitized electrical power distribution system gives you the deep insights you need so you’re no longer ‘working blind’.
In this post, we’ll have a look at the specific digital technologies that can help you achieve your continuity and efficiency goals faster, while making your job easier.
Digitization is everywhere
Just about every aspect of our lives has become digitized. Consider the vehicle you drive. If you have a fairly recent model, every aspect of its operation is monitored, displayed and, in some cases, controlled automatically. These advances are making driving safer, more reliable, more efficient, and compliant with regulations like emissions standards. It’s also making driving easier and more enjoyable.
Dealing with the complexity of modern vehicles without the help of digitization is almost unthinkable. Imagine troubleshooting a problem without a diagnostic scanner. The same is true for electrical distribution systems, which have become increasingly complex, with:
- More loads, many of which are increasingly power sensitive
- Many types of loads, such as variable speed drives, that can also be the source of potential power quality issues
- Onsite generation and storage, needing to be carefully coordinated for power backup, peak shaving, or consuming renewable energy when it’s most economical
As the complexity and sophistication of our electrical distribution infrastructure increases, it becomes more important to have the appropriate digital sensors, advanced controls, and analytic capabilities to detect, diagnose, and correct issues before they cause mission-critical systems to fail.
Getting connected
Unlike today’s vehicles, power distribution systems do not come ‘stock’ with complete digitization; though, in future it’s expected they will. The good news is that your electrical network may already be part of the way there.
For example, your switchgear and distribution panels may have digital power meters and smart circuit breakers in place that provide connectivity capabilities, some with modular options. Even legacy systems can be retrofit with communicating devices and sensors. These upgrades are still very cost-effective when considering the vast benefits and ROI of digitization.
The global trend in the Internet-of-Things is enabling more connectivity and intelligence in more kinds of devices, from breakers and meters, to power quality monitors and busbar temperature sensors, to equipment with embedded sensors like UPSs and gensets, to automation equipment like PLCs.
You can choose from a variety of communication standards, from the affordability of wireless to the high-speed performance of Ethernet. Open, non-proprietary communications protocols are making it easier than ever to get all these devices talking and sharing information.
The brains behind it all
Smart devices in your power network will perform a lot of metering, logging, and analysis. IoT-enablement means that data can be shared easily with cloud-based storage and applications, while mobile apps can access each device’s on-board data and functions.
All of this means your operations and maintenance personnel get easy, fast access to important information and alarms from wherever they are, with the ability to collaborate across your teams.
Above it all are powerful software applications, aggregating and analyzing data from across one or more of your facilities. These cloud and facility-based apps are where the full potential of digitization is realized, letting you see into every corner of your electrical systems, supervise every electrical process, get early warning of every risk, and capture every opportunity to improve power, energy, and equipment performance.
A fully digitized power distribution system will help you optimize safety for people and assets, while improving reliability and business continuity. It will give you the tools to maximize energy and life cycle efficiency while enabling condition-based maintenance. It will simplify energy and emissions tracking. And for facilities with limited resources, a cloud-based platform can act as your doorway to 24-hour support from expert services.
In my next post, we’ll dig into these benefits further to see how digitization can deliver a very big payback in a very short time.
