Wind and Photovoltaic Industry
Digital power supply and distribution solutions for photovoltaic power generation industry.
Industry Pain Points
-
Unstable Power GenerationPV output fluctuates sharply with sunlight such as cloudy days, nights, causing unstable supply and challenging voltage and current regulation of distribution systems.
-
Grid-connection FluctuationsPV grid-connection may affect distribution network voltage; excessive PV output creates reverse current, straining traditional systems.
-
Outdoor Harsh ConditionsOutdoor-installed PV equipment demands distribution devices with sunproof, waterproof, and anti-corrosion capabilities to withstand extreme weather like high temperatures, strong winds, heavy rains.
-
Complex MaintenanceWidespread PV components and distribution devices raise maintenance costs, requiring intelligent remote monitoring and auto-diagnosis.
Daqo Solutions
PV digital power systems upgrade traditional electrical equipment and components in mechanics, operation, arc suppression, earthquake resistance and energy efficiency, ensuring higher-performance primary equipment meeting stricter standards.
Daqo's system uses domestic high-performance embedded platforms and IEC 61850 for advanced integrated power monitoring, with a "cloud-pipe-edge-device" architecture enabling intelligent O&M of PV power systems and supporting full-life-cycle equipment management.
