Smart Grid Surveillance

A true digital transformation of the power grid

 
 

The power grid today is formed by linked metal wire, just like the telephone network 100 years ago. There is no built-in intelligence like in the Internet. Knowing the status of the grid is thus hard. Often, Grid troubleshooting consists of simple trial-and-error. This takes time, requires lots of manpower which cost loads of money! Meanwhile, otherwise operational areas are affected by both the fault itself and the troubleshooting process.

Smart Grid Surveillance™ performs the digital transformation and makes your grid smart. It gives a complete view of the current network status. Faults are instantly classified and located. Immediate actions can be taken to restore secondarily affected areas and send repair crews directly to the fault location. Instead of waiting for customers to call about the problem, affected customers can be directly informed about an issue and the time until it is fixed.

Dangerous situations like hanging lines or tilted poles can be detected and fixed before damages or injuries occur.

Rather than having reoccurring faults leading to costly actions, intermittent faults are tagged by location when they occur, which enables correct maintenance.

 

Surveillance of the grid like never before. 

 
 

SGS has possibilities never seen before to detect and localize problems in a power grid, presenting a situation picture with both status and decision support.

No further analysis is required by experts, the results of the SGS conclusive analysis is already there. A major part of why this is possible is the complete system approach.

Thanks to the cooperation between intelligent agents, mounted on the grid poles, and the ICCU (Intelligent Collecting and Conclusion Unit) SGS can present the complete status of the grid. ICCU also collects statistics to make a long-time evaluation of grid performance. As a result, SGS can not only see current faults but also predict upcoming problem lines or areas in need of maintenance.

Artificial intelligence

The agents, which are mounted out of contact with live wires, sends information about what is happening in the grid to the ICCU. Together, they give an insight in what is currently happening in a previously non-intelligent network.

The ICCU in turn uses AI algorithms and big data analysis to draw conclusions from the collected information. The agents are intelligent, but cannot by themselves see the bigger picture of the grid, and thus the ICCU algorithms are necessary to accomplish a situation picture comprising all the grid.

Built-in communication

To complete the picture, SGS has its own communication solution, making sure that information between Line Agents and the ICCU are exchanged properly. This guarantees not only energy efficiency and reliability, but also high security.

The whole system approach gives the grid owner simplicity, as the complete current status is always available. Reliability in the system is achieved by long-life batteries and redundant communication paths. If an agent for some reason goes out of order, this is also clearly visible to the user. The only effect on the complete system will be that fault localization will be done with lower granularity for the affected line part.

It should be noted that due to their mounting well below the lines, the agents are protected from the effect of lightning strikes in all cases except a direct hit.

Low cost and long life

The system is simple to install and self-calibrating, as the AI makes sure that all agents are updated according to current conditions. It runs for years without maintenance with a low cost operation.

The result of the complete system design is that, as grid owner, you can after installing the agents exactly where you want your grid monitored, just sit back and watch the current situation unfold.
