Project Overview:
QZ Switchgear provided a turnkey MV/LV distribution system for a 100MW solar power plant within the Benban Solar Park, one of the world’s largest PV clusters. The equipment was distributed across multiple inverter stations and step-up substations, ensuring reliable evacuation of renewable power into the 220kV national grid.
Technical Highlights:
Medium Voltage Side
-
33kV KYN28 panels for incoming, outgoing, and bus-coupler applications
-
Integrated with ABB and Siemens protection relays, IEC61850 protocol-ready
-
ZW32-12 recloser breakers deployed on overhead feeders for remote sectionalizing
Transformer Section
-
Oil-immersed 5000kVA step-up transformers converting 0.6kV inverter output to 33kV
-
ONAN/ONAF cooling design, suitable for desert high-temperature (50°C+)
-
Nitrogen protection system and corrugated tank design to extend service life
Low Voltage Side
-
GCS LV switchgear for inverter output collection and auxiliary loads
-
Compensation cabinets designed with detuned reactors to suppress harmonics
-
Integrated RTU for remote monitoring of power factor and breaker status
SCADA & Control
-
All equipment linked via fiber optic ring to site control center
-
Remote reclosing and fault detection enabled through GSM/GPRS backup channel
-
Data fully compatible with Egyptian Transmission Company’s grid management system
Client Benefits:
