Recently, a major milestone was achieved in the nation's first offshore wind power sea-land integrated flexible HVDC transmission project—the Yangjiang Sanshan Island Offshore Wind Power Flexible HVDC Transmission Project of China Southern Power Grid Guangdong Power Grid. The offshore converter station has been fully assembled and shipped, marking the project's full-scale entry into the offshore installation phase. Under the isolated island operating conditions of the deep-sea environment, EVOTEC alternators were simultaneously installed, standing ready with robust product performance to silently safeguard the starting point of this "green power expressway."
From core technology breakthroughs to extreme environmental adaptability, EVOTEC has delivered solid power assurance for this world-class project through its exceptional R&D and manufacturing capabilities:
✅ Low-distortion high-quality power output: Optimized 2/3 pitch winding + damping structure, with total harmonic distortion (THD) ≤ 1.6%, delivering excellent harmonic control that precisely meets the stringent requirements of flexible HVDC transmission system precision equipment;
✅ Grid-friendly paralleling performance: Professional AVR excitation control system with excellent dynamic voltage regulation accuracy, well-suited for multi-unit coordinated grid-paralleling scenarios in flexible HVDC projects.
Facing the harsh conditions of the South China Sea—high salt spray, strong typhoons, and continuous vibration—EVOTEC alternators, with their triple anti-corrosion coating, low-harmonic high-quality power, and vibration-resistant stable structure, perfectly match the auxiliary power supply needs of the offshore converter station, ensuring stable operation of this "offshore power expressway" with domestically manufactured hardcore equipment.
Upon completion, the project is expected to deliver approximately 6 billion kWh of clean electricity annually to the Guangdong-Hong Kong-Macao Greater Bay Area, equivalent to saving 1.74 million tons of standard coal and reducing carbon dioxide emissions by about 4.63 million tons—serving as a powerful green engine for the region's high-quality economic development.
From nearshore to deep-sea, from onshore grid extension to offshore flexible HVDC mega-hubs, EVOTEC Electric has consistently leveraged its comprehensive technical capabilities to provide stable and reliable domestically produced power assurance for critical national engineering power supply projects.
This partnership with the Sanshan Island world-class offshore flexible HVDC project represents the industry's high recognition of EVOTEC's product reliability and marine environment adaptability. Looking ahead, EVOTEC will continue to deepen its presence in the power equipment sector, underpinned by independent core technologies, and contribute even stronger domestic capabilities to national-level power infrastructure development.
