Automated recoupling in smart secondary substation (Finalised)
When customers lose power due to a fault, it is in the best interest of both the customer and the grid company to restore the power as quickly as possible. But localising and fixing a fault is often time-consuming and costly.
Automatic, close to instant fault location and recoupling can reduce the time it takes to restore power after a fault. Lnett is testing an algorithm for automatic recoupling in an area with long distance overhead lines with frequent faults. The selected secondary substation is equipped with remote control and monitoring and came be fed from two sides.
