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.
