Faults are detected via measurements in SCADA, data from AMS smart meters or customer notifications.
"The system provides grid companies with a quick overview of the number of customers affected by a power outage, how large an area is affected and the cost and resource requirements for fault rectification," says Sjur Messel Nafstad, product owner at Powel.
“The grid centre receives this information through the system automatically,” says Nafstad.
ADMS calculates how many customers must be notified and provides templates for which type of SMS message should be sent.
Trees falling on the line
ADMS has calculation options that help the grid centre locate the probable fault location. Power outages often occur because of trees falling on the line. Excavation work can also sometimes damage power lines.
“The system helps grid companies quickly identify the correct location so they can repair the grid, as well as help operators assess how the fault should be managed,” says Nafstad.
