Planned outage of Tailem Bend 275kV - South East 275kV No.2 line from 16/07/2016 0745 hrs to 24/07/2016 1730hrs
?
During this outage, South Australia (SA) will remain connected to the NEM via the Tailem Bend - South East No.1 275kV line and the 132kV network.
?
A trip of the Tailem Bend - South East No. 1 275kV line will sever the 275 kV connections between the NEM and SA. SA will remain connected to the NEM via the 132kV network, which if it remains in service will pose a system security issue.
?
In the event of a trip of the Tailem Bend - South East No. 1 275kV line, AEMO will invoke FCAS regulation constraint sets F-S_LREG_0035 and F-S_RREG_0035
?
In addition,? AEMO will take all necessary steps as outlined in Section 6.1 of SO-OP-3715 Power System Security Guideline to separate the 132kV network and therefore manage an orderly separation of SA from the NEM.?
