"Since 2003, Rede Eléctrica Nacional (REN) uses real time lighting information as it has an important and critical role for High Voltage Grid operation.
Before and/or during grid maintenance operations, REN operator decides to validate or cancel planned operations if storm is approaching work area.
For areas where lighting is observed, REN uses N-2 security criteria at towers supporting 2 circuits as risk of having a fault that could affect both circuits will be maximum.
A risk application is being developed in order to calculate fault probability for each line.
We are using METEORAGE realtime information for this pilot application.
For backoffice analysis of each High Voltage fault of Portuguese grid, we do an offline study using METEORAGE service that allows to clearly and rigorously identify electrical power grid faults.
Lightning detection METEORAGE Service has low error margin which improves the quality of the data collected.
Fault analysis is now much quicker and accurate! "
