In view of the national strategic goals of "carbon peak and carbon neutrality", rapidly reversing the energy structure and improving the utilization rate of renewable energy is the inevitable choice to promote high-quality development during the "14th Five-Year Plan" period. With the development and construction of large-scale onshore renewable energy bases, it is the trend of electric power development during the 14th Five-Year Plan period to use flexible DC transmission technology for the long-distance transmission of renewable energy. TBEA boasts ±800kV flexible DC transmission converter valve, and based on the technology of "DC FRT control", has designed the local port support, full-bridge lines and low-cost system schemes for onshore overhead lines. With the flexible DC system design capability for multiple application scenarios, we provide the owners with economic system schemes suitable for the delivery of renewable energy.
MORETo meet the requirements of offshore applications, the system delivery scheme was designed for a lightweight and compact offshore wind power converter based on its ±800KV UHV flexible DC transmission technology and capacity of supplying primary equipment for flexible DC systems. The system was optimized to reduce module capacitance, the number of modules and the loss. At the same time, a more competitive new topology scheme was put forward in line with the development trend of the industry. On the premise of ensuring reliability, the power density is further improved through compact and lightweight design. The modular centralized energy discharge device of offshore wind power with independent intellectual property rights was adopted to prevent the failure of the onshore AC system from affecting the offshore wind power system and ensure the safe and reliable operation of the whole system.
