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:
Single-source supplier reduced EPC coordination effort by 40%
Desert-adapted design ensured stable operation under sandstorm and high UV exposure
Pre-engineered containerized substations accelerated project delivery by 3 months
Full FAT conducted in China with client engineers present, reducing site commissioning risk
