Yass to Wagga control scheme change - removal system normal constraint equations in NSW managing 990, 991 and 970 132kV lines
AEMO ELECTRICITY MARKET NOTICE
Transgrid has advised AEMO of an update to the Yass overload trip scheme. The scheme is normally armed managing line flow on 990, 991, 970 132kV lines and it is now operating both directions of flow from Wagga to Yass.
Based on this advice, the following constraint equations will be removed from the NSW system normal constraint sets N-NIL and N-NIL_991, effective immediately.
N>>NIL_970_051
N>>NIL_990_051
N>>NIL_991_051
