Logical nodes for power quality events LN Group: Q
-
Modelling remarks
-
This group of logical nodes refers to the modelling of power quality events detection and analysis functions. The models are based on the principles used for modelling protection functions. .
There is a one-to-one relationship between the power quality event logical nodes in IEC 61850-5 and the logical node class definitions in this standard.
