The Scope of Works for the Woomera Electrical Infrastructure Works consisted of a “like-for-like” replacement of the existing substation with a new Manual of Infrastructure Engineering (MIEE) compliant substation, consisting of the following main elements:
The substation consists of the following key elements:
- A new elevated transportable switchroom building housing
- 33kV fixed switchgear
- 11kV withdrawable switchgear
- Redundant battery charger and battery system
- Protection and control panels, low voltage distribution boards, fire alarm system and telemetry system
- Spatial provisions for future PCMS equipment
Two (2) new outdoor 33/11kV 2.5MVA transformers, one (1) new outdoor 11/0.4kV 250kVA auxiliary transformer and associated cabling to interface with existing incoming and outgoing overhead distribution lines. This is secured with new substation compound fencing, lighting and access roads.
Demolition of the existing outdoor switchyard, switch room building and existing 33kV, 11kV and 0.4kV incoming and outgoing supplies was required and subject to strict environmental requirements.
