Engineering Overview
This landmark clean energy project comprises a 100MW grid-tied photovoltaic power generation facility spanning over 350 acres. WIN-TEC ELECTRICAL delivered the complete balance-of-system (BOS) electromechanical engineering package, high-voltage stepping substation, and automated SCADA control interconnect.
The Challenge
Interconnecting 100MW fluctuating solar power to the national transmission grid required ultra-fast voltage regulation, reactive power compensation (STATCOM), and harmonic mitigation without causing grid instability during peak cloud transients.
The Engineering Solution
WIN-TEC engineered dual 33kV collector busbar switchboards with integrated active power curtailment and central dynamic VAR controllers. We implemented an automated SCADA control center featuring fiber-optic IEC 61850 communications to communicate real-time grid conditions with the National System Control Centre (NSCC).
Key Scope & Technical Deliverables
- 100MW DC-to-AC centralized inverter stations and transformers
- 33kV indoor gas-insulated switchgear (GIS) with remote tripping relays
- 35km of underground medium-voltage XLPE cable laying and terminations
- Utility-approved revenue metering cubicles and dual optical communications
- Class 1 lightning protection grid covering the entire 350-acre facility
