FEATURES - THE HOT LIST

Smart Grid Hot List: Transformers No Disguise


Electricity, plumbing, and weather often are places where my knowledge shows huge gaps. I understand the workings in general, but by in large I accept my knowledge gaps as the world maintaining it’s magic, wonder, and awe for me. So I am going to do my level best to keep the magic alive while educating my readers and myself with some insight about transformers.

Now for those who don’t read me often enough to know that I have been on a soap box about AMI being a top driven deployment that did little to support consumer’s managing their systems, the fact that I have chosen to look at transformers may seem odd. If I want demand response capabilities, I should talk about them. However, in my opinion transformers are where the smart grid will be most apparent. In addition, the same companies that build transformers build most power generators. Another parallel to the past is the way cable operators came of age with network management systems.

For the cable operators in the past, management relied on consumer repair calls to isolate the trouble. As one ops executive said, “usually by the end of an hour we hear from enough customers to determine the point of failure.” While power has a history of responding much faster, much of that has to do with the involvement of first responders.

The point I am trying to make is that power companies have a large transition they have to achieve in managing the smart grid.

From a total picture perspective, transformers themselves are not where energy is being lost. In fact, transformers’ 3 percent loss represents one of the most efficient parts of the smart grid. I choose to focus on transformers’ roles in smart grid for a few simple reasons. The first is from my bell head, I think of transformers as being the equivalent of cell towers, where aggregation and distribution occurs. The second is that if demand/response is being enabled, transformers will be a focal point of interaction. Last but not least, as micro grids and home generation occurs, transformers are going to be gateways between systems.

From a business perspective, transformers are going to need some reformation in the way they are analyzed and deployed. Like telephone switches before the death of rate of return regulation, transformers are looked at from the perspective of 30- or 40-year life cycles. So that makes the adoption of new technologies slow moving. It also means that adjunct systems are going to be popular and government policy can have a huge impact on capital expenditures. Synchrophasors have been added to networks to give a complete picture in time of where the power anomalies lie. In effect, this provides the raw data that makes the smart grid analytics allow operators to better interpret simulations, react to outages, and prevent outages before they occur.

The Need for Speed

As a result of this migration to  synchrophasors, the analytics are coming to the operators 100 times faster than past operations. This, of course, has added to the need for training and education within the power companies. According to a Federal Regulatory Energy Commission report, “the placement…throughout the transmission grid permits grid operators to identify and correct for system instabilities, such as frequency and voltage oscillations, and operate transmission lines at great capacities….”

In one case the report sites success in delivering 100MW more output, while reducing the energy expense by 35 to 70 MUSD. The success of this has lead to the growth of 35 percent of synchrophasors technology for the last six years.

An important aspect of this is the change in analytics overall. Dr. Dale Skeen, CTO of Vitria, has discussed the impact of gathering real-time information in the power grid. It increases the ability of the utility to react proactively with predictive and preventative solutions.

Skeen goes on to say “with each passing moment we see a significant amount of new data, from which we can detect anomalies and deviations from plan early; predict problems early; and consequently, we can act in time to avoid or mitigate problems.”

Fast Analytics over Slow

Data has one other major advantage. It can future-proof you against ever faster data cycles. Today it may be daily, next year, hourly, and the year after, every 15 minutes – it doesn’t matter, and fast analytics can always keep up. So, as your data cycles increase and your time-to-action decreases, streaming analytics can keep up, no matter how fast your data cycle times.

This is significant since the data from the existing power system, as I have indicated, has not traditionally been slow. From this point of the view, the investment in AMI started the ball rolling for the utilities to learn to upgrade their analytics. This hot list focus on transformers, it needs to be understood, is not about the hot market but rather the overall transformation to more efficient transmission.
