(MPCo) successfully completed the acceptance and energization of the 110kV, 50MVAr capacitor bank at Hiep Hoa 500kV Substation (Bac Giang Province), under Package No. 3: Supply and Delivery of Primary Equipment issued by the Power Transmission Project Management Board of Vietnam.
Energization of the 110kV, 50MVAr Capacitor Bank at Hiep Hoa 500kV Substation
Project Information
- Project Name: Hiep Hoa 500kV Substation
- Investor: Power Transmission Project Management Board – a branch of the National Power Transmission Corporation (EVNNPT)
- Location: Dai Thanh Commune, Hiep Hoa District, Bac Giang Province
- Implementation Period: November 2024 – April 2025
The capacitor bank is manufactured by Eaton’s Cooper, a company with over 80 years of experience in the electrical equipment industry. It utilizes internally fused capacitor units of the EX-7Li type, with a rated voltage of 15kV and a capacity of 565 kVAr per unit, with a total of 120 units (50MVAr per bank).
The commissioning of the capacitor bank contributes to maintaining transmission grid voltage in the Northern region within permissible limits, meeting the increasing power demand of critical loads. It also enhances the stability of power supply, reduces power and energy losses, and thereby improves the operational and business efficiency of Vietnam Electricity (EVN).
