NS210: Documentation and Reference Design Guide for Major Substations

Details general documentation and reference design guidance for the Environmental, Civil, Architectural, Electrical Primary and Electrical Secondary aspects that shall be considered and included into the design of major substations.

Scope

This Network Standard applies to new major substations and to significant augmentation works at existing substations. It shall also apply, as directed by Ausgrid’s Engineering, to programmed replacement of equipment on a like for like basis. Its application to unscheduled or breakdown restoration works, and to other works, is by exception only and shall be as directed by Ausgrid’s Engineering.

Requirements are included for environmental, civil, architectural, electrical primary, electrical secondary, control, protection, communications and SCADA aspects that shall be considered and included into the design and construction of Ausgrid’s major substations.

This Network Standard:

• applies to sub-transmission substations (132kV/66kV/33kV, 132kV/66kV, 132kV/33kV) and
  typically these substations utilise transformers having nameplate ratings of 60MVA and
  120MVA.
• applies to zone substations (132kV/11kV, 66kV/11kV, 33kV/11kV) and typically these
  substations utilise transformers having nameplate ratings of 19MVA, 33MVA, 37.5MVA and
  50MVA.
