Milestone: CRRC Zhuzhou Institutes 12MW Offshore Doubly-Fed Wind Turbine Successfully Hoisted

Milestone: CRRC Zhuzhou Institute's 12MW Offshore Doubly-Fed Wind Turbine Successfully Hoisted

On August 3rd, the independently developed 12MW offshore doubly-fed wind turbine by CRRC Zhuzhou Institute was successfully hoisted. This marks that China’s offshore wind power equipment can provide new system solutions for high-quality marine energy development, helping to achieve carbon peak and carbon neutrality goals earlier.

Tech Highlights: Reliable, Efficient, Smart & Grid-Strong

The 12MW offshore doubly-fed wind turbine embodies CRRC Zhuzhou Institute’s profound technical accumulation and continuous innovation. It deeply inherits CRRC’s proven "high-speed rail-grade" long-life and high-reliability genes in high-end equipment. Through in-depth optimization of key components, it demonstrates excellent adaptability to marine environments, maintaining stable performance especially under extreme conditions like high salt spray corrosion and strong typhoons, providing solid guarantees for the safe and reliable lifecycle operation of offshore wind farms.

In terms of power generation performance, the turbine integrates self-developed high-efficiency doubly-fed converters, advanced intelligent control strategies, and sophisticated aerodynamic design, achieving dual leaps in overall operational efficiency and wind energy capture efficiency, with significantly improved power generation economics.

Meanwhile, it boasts industry-leading grid adaptability and support capabilities: not only meeting the world’s strictest Low/High Voltage Ride-Through (LVRT/HVRT) requirements but also proactively providing critical support functions such as inertia response and primary frequency regulation, making it an ideal choice for building a safe and stable new power system. Additionally, the turbine integrates an advanced intelligent operation and maintenance system, enabling predictive maintenance through big data analysis and intelligent diagnostics, effectively addressing the high cost of offshore operation and maintenance and improving wind farm operational efficiency.

Committed to Doubly-Fed Technology: Heritage, Maturity & Innovation

Facing the trend of offshore wind power developing toward higher power capacity, CRRC Zhuzhou Institute has firmly chosen and continues to lead the doubly-fed technology route. This route is rooted in CRRC’s globally leading high-power transmission, converter, and control technologies in rail transit—a strong technical foundation—and represents the extension and amplification of homologous technical advantages, forming CRRC’s core competitiveness in offshore wind power.

Moreover, doubly-fed technology, with advantages of a highly mature industrial chain, stable and reliable supply chains, and excellent mass production costs, has undergone full verification through large-scale global onshore wind power applications. Its operational convenience and long-term reliability are particularly prominent in complex offshore environments. CRRC Zhuzhou Institute has deeply empowered it with high-speed rail-grade efficient converter and intelligent control technologies, fully unleashing technical potential to precisely meet the high-performance demands of large-power offshore wind turbines.
