Offshore wind turbine collector system

Offshore wind turbine collector system

TBEA has independently developed offshore wind turbine nacelle transformers, compact offshore wind tower HGIS, and 66 kV/14 MW offshore wind tower transformers, which collect the electricity generated by wind turbines through marine-resistant twisted flexible cables, connecting it to the offshore step-up station. The entire product line is designed to withstand the harsh conditions of the marine environment, ensuring the stability of the transmission system.
Offshore substation AC transmission system

Offshore substation AC transmission system

We have independently developed the first 330 kV substation platform and key equipment technology in China. This technology has enabled the safe and stable operation of the main transformer, GIS, and reactors in offshore substations. We have also successfully developed converter valves and valve control products for high-voltage flexible low-frequency AC transmission in offshore applications. This establishes us as China’s leading enterprise with the most extensive operational track record in offshore step-up platforms and the largest portfolio of supplied offshore wind projects.
Offshore converter station flexible DC transmission

Offshore converter station flexible DC transmission

Moving from nearshore to the more wind energy-rich deep sea, we have tackled the global challenge of ultra-high-capacity, long-distance, efficient, and stable power transmission for offshore wind power. We have achieved multiple results in core equipment such as interconnecting transformers and flexible DC converter valves. These innovations optimize the power flow distribution in the grid, enhance the economic and secure operation of the power grid, and better address the intermittency and variability of wind power, facilitating the friendly integration of new energy sources.

Real-time monitoring of all equipment status in offshore step-up stations, incorporating smart alarms, online power equipment diagnostics, and wireless communication technologies into O&M processes, significantly reduces maintenance costs in harsh marine environments. Our solutions have been deployed in 1,000+ projects, demonstrating extensive implementation expertise and robust product service capabilities.

Integrated Solution for Offshore Wind Power System

Solution Value

High-Reliability Design

Utilizing a compact and lightweight architecture combined with intelligent anti-corrosion technology, the industry’s first C5-H anti-corrosion certification has been obtained. The solution has been verified against wave and high-salinity fog conditions, achieving lifecycle stability that meets international standards.

Cost-Efficient Management

Through standardized design, large-scale procurement, and a digital O&M platform, the comprehensive cost of equipment has been reduced by 38%, realizing the most economical configuration of the electrical system for offshore platforms.

Core Technology Breakthroughs

We have mastered core technologies such as flexible HVDC and low-frequency valve control. Independent research and development of MMC converter valves and M3C low-frequency valves have established a comprehensive intellectual property rights technology system, with technical indicators leading the industry.

End-to-End Integration Empowerment

The solution integrates AC/DC transformers, GIS, switchgear, and other equipment, establishing a supply chain from core components to system integration to ensure efficient project delivery and synergistic full lifecycle development.
