When there is an outage involving smart grid hardware, there can be real problems. If data is lost, there can be serious costs. This is why most smart grid solutions utilize an uninterrupted power supply, or UPS. UPS systems consist of heavy-duty DC battery chains that kick in during an outage or interruption ensuring proper system shutdown of technologies and machinery before the generator can power on. More simply put, the smart grid protects the consumer, and the UPS protects the smart grid. But what protects that? Battery Management Solutions help to tie off loose ends in communication and connectivity in case of outages.
Layered IoT Protection
Having a UPS is good, but it doesn’t make a system infallible. DC batteries are prone to factory defects, damage, wear-and-tear and failure just like any other equipment. In fact, about 80% of UPS system failures result from overcharging these batteries.
Not having a solution in place to monitor DC power supply leads to some serious costs for businesses:
- Frequent, unnecessary replacement of batteries
- Expensive testing equipment and protocol
- Ongoing personnel dispatch to remote locations
Simple tests and averages can give you some idea of how your batteries are holding up, but estimates are often unreliable. Field tests of heavy-duty batteries show there is a 40% chance of battery failure after seven years. However, tests by engineers at MGE UPS systems predict that there is a higher spike of battery failure around four years.
This test data is nice to have, but how do utility companies apply the data in the field? Simply replacing all batteries every four years makes no sense. Just because some have failed doesn’t mean the rest are doomed. Testing the discharge of the chain of batteries also won’t do; discharge data from the chain does not reflect individual battery health, or probability of failure. When one battery in a chain dies, the others work overtime to keep up, skewing results in a discharge test.
The only way to accurately diagnose the health of a battery chain is to test each battery individually. Testing each and every battery in a chain is a laborious undertaking, and with many DC power supplies stationed remotely, dispatching crews makes it even more impractical.
IoT Monitoring of DC Power
Luckily, the solution to protect DC power supplies is “smart” as well. Similar to the design of smart grid solutions, companies are taking advantage of Battery Management Systems, or BMS solutions to monitor DC power health with access to real-time operational and field data. With plug-and-play software and scalable designs, a well-managed BMS solution with IoT remote monitoring is the last piece of the puzzle for tech in utilities.
The IoT model for grid services proves to be an unbelievably effective way to save manpower, equipment and time. The same model lends itself towards all of the DC battery applications as well.
A well-managed BMS system can “speak” if there’s a problem, and the system allows for automation of repair and replacement schedules. This can all be done from a tablet or phone, remotely.
BMS IoT platforms take care of:
- Integrated and automated communication between components
- Sensing and measurement
- Automated alerts for distribution and repairs
- Real-time analytics and historical data
Whether it’s for a UPS, utility substation, or a wind-solar solution, grid services utilize some form of stored DC power. The BMS transforms a once tedious, expensive effort into a streamlined process that saves time and money for utilities.
