Substation Design & Construct
- Middlemount Coal
This project involved the design, supply, delivery, construction and commissioning of a new high voltage substation to provide 11kV and future 66kV distribution supply to the Middlemount Coal Mine, which is located 8.0km west of the town of Middlemount in Central Queensland.
Wave International was responsible for the design and construction of the substation. The protection, controls and 11kV distribution was designed and installed into a 10ft shipping container allowing a very small foot print when compared with traditional substation layouts. Wave was also responsible for programming the control and protection relays (ABB REF615, ABB RET630 & ABB REF630).
The pre-fabricated, compact design allowed work to be done offsite with the exception of termination of the 66kV lines, earth grid and fencing, which allows for an easy relocation of the substation if required. This innovative approach resulted in reduced construction time, with significant savings in costs and materials.
