Energy-type High-quality Power Supply

Leveraging advanced and mature grid-forming technology, we have developed high-quality power supply solutions that deliver comprehensive mitigation of power quality issues such as voltage sags and short interruptions. Supporting connection voltage levels ranging from 0.4 kV to 35 kV, the solutions enable centralized governance for an entire substation or a complete bus section.

  • Centralized Voltage Sag Mitigation

  • Zero-Latency Frequency and Voltage Stabilization

  • Extended Functional Capability

  • Full-Lifecycle One-Stop Service System

Product Highlights

Centralized Voltage Sag Mitigation

Centralized Voltage Sag Mitigation

Centralized mitigation of voltage sags for 0.4 kV – 35 kV systems. It can be flexibly deployed at positions such as the medium-voltage incoming side, outgoing side, transformer high-voltage side and low-voltage side. It realizes centralized voltage sag mitigation for the whole substation or an entire bus section. Equipped with fault direction identification capability, it can effectively avoid false operations caused by load-side faults.

Zero-Latency Frequency and Voltage Stabilization

Zero-Latency Frequency and Voltage Stabilization

Adopting industry-leading grid-forming voltage source technology, the system delivers zero-latency natural response and maintains stable voltage and frequency during transient conditions.

Extended Functional Capability

Extended Functional Capability

While realizing voltage sag mitigation, the system integrates multiple functions including peak-valley arbitrage, power factor improvement, unbalance mitigation, harmonic mitigation, emergency power supply, demand response and demand management.

Full-Lifecycle One-Stop Service System

Full-Lifecycle One-Stop Service System

We provide full-lifecycle one-stop services including site survey, solution planning, simulation verification, customized design, as well as dual operation and maintenance support covering cloud platform and user terminal.
