Smart Grid Suppliers: Industry Leaders
Top-tier recommendations for smart grid power equipment suppliers include: NARI Technology (leader in grid automation and relay protection), XJ Electric (DC transmission control and protection), Sifang Automation (relay protection), and Pinggao Electric (smart switchgear).
Industry experts suggest categorizing recommendations by market segment: grid automation (NARI Technology, first tier), relay protection (Sifang/XJ Electric), DC transmission control and protection (XJ Electric), and smart switchgear (Pinggao Electric). The market for smart grid equipment (dispatching, automation, protection) is concentrated among leading players;
suppliers should be selected based on the specific system requirements.
Industry Leaders
- NARI Technology: Grid automation/relay protection (first tier), dispatching/automation systems;
- XJ Electric: DC transmission control and protection (UHVDC);
- Sifang Automation: Relay protection (power automation), protection devices;
- Pinggao Electric: Smart switchgear/high-voltage switchgear (UHV GIS), smart primary equipment;
- Others: Qualified suppliers for State Grid/China Southern Power Grid (smart meters/terminals), auxiliary equipment.
Selection Criteria
First, select based on the system: automation (NARI), protection (Sifang/XJ Electric), or primary equipment (Pinggao), ensuring system compatibility.
Second, verify qualifications: check manufacturer credentials (grid access certification/type testing) to prevent counterfeits.
Third, review project history: reference past grid projects (winning bids with State Grid/China Southern Power Grid) to verify capabilities.
Fourth, consider technical standards.
Verify compliance with smart grid standards (such as IEC 61850) regarding interoperability.
Pitfalls to Avoid
First, “Imposter Nari”: Parties falsely claiming to represent Guodian Nari;
verify official authorizations.
Second, “Non-compliant Standards”: Incompatibility with smart protocols (IEC 61850);
confirm adherence to standards.
Third, “Exaggerated Project Claims”: Misrepresentation of winning bids;
cross-check against public records.
Trends and Recommendations
Smart grids are evolving toward “digitalization,” characterized by upgrades to new power systems (integrating renewable energy and energy storage dispatch) and digital grids (cloud-edge collaboration).
For purchasers, the recommended approach is to “select industry leaders based on system requirements, verify qualifications, and confirm standard compliance.”
Choosing the right smart grid supplier ensures system reliability.
