P30286_Eskom Qunu substation Basic Assessment

 

The proposed project involves the provision of infrastructure to ensure the protection alignment needs between Vuyani MTS (Mthatha area) and Qunu substation and also to align Qunu substation with Eskom’s Network Planning Reliability Guideline.

 

Due to the T-off arrangement from the Tyalara/Zimbane 132kV lines, the performance of supply on the 22kV networks is affected by any operating (switching) and faults that occurs on either Tyalara/Qunu 132kV or Zimbane/Qunu 132kV sections of the Tyalara/Zimbane 132kV line. Also, due to the total number of customers (26 000), Qunu substation requires dual transformation as this substation does not align with the Network Planning Reliability Guideline. A transformer failure could affect the performance of the 22kV networks resulting to negative impact on Key Performance Indicators. The Qunu- Mqanduli 22kV feeder does not comply with the Network Planning Reliability Guideline due to the number of customers supplied by this feeder. Therefore network reinforcement is required in order to align Qunu substation with the Network Planning Reliability Guideline.

 

The project consists of three aspects:

 

  • Qunu 132/22kV Substation Extension- the extension will be inside the substation and diversion of the 132kV line
  • Tyalara Substation – Qunu 132kV Feeder Protection Upgrade
  • Qunu Substation 22kV Link Lines and upgrading the existing 22kV line

 

The existing Qunu substation is located less than 2km south west of Qunu Village within King Sabata Dalindyebo Local Municipality (OR Tambo District Municipality) of the Eastern Cape Province. The Qunu substation is positioned approximately 32km South of Umtata, along the N2 between Umtata and Butterworth.
