On March 31, the 300kW marine tidal current generator set independently developed by Guodian United Power Technology Co., Ltd., which uses the 270° electric pitch technology and underwater video technology, successfully went to the sea and smoothly connected to the grid for power generation and operation.
This is the world's first tidal current generator set that uses 270° pitch technology to achieve efficient capture of two-way current energy. The joint power rate first overcomes the technical bottlenecks of current fluctuations and pitch-coupling effects on the stability of the unit, and developed the first domestic case. Power generator set using electric pitch technology. For the developed countries in Europe and the United States only applying the 180° pitch technology, the problem of low energy capture efficiency, joint power concentrated on five years of serious research, developed a more advanced 270° electric pitch technology, The pitch range is larger, the pitch strategy is more flexible, and the full capture of forward and reverse currents is achieved to achieve the best energy capture and power generation efficiency.
This unit is also the world's first tidal power generator set that uses underwater video technology to monitor the safety of the unit. It continuously monitors the critical parts of the unit for the entire life cycle. This is the first time in the world. R&D and design are completely independent intellectual property rights. The project has obtained 22 authorized patents, including 7 invention patents; participated in the preparation of 1 national energy industry standard; published 10 high-level research papers. This technology innovation won the 2017 National Ocean Science and Technology Award. Awards, to achieve the world leading power generation technology of the ocean current, to promote China's ocean current power generation technology to achieve a giant leap into the world advanced.
Tidal ocean energy is an important new force for the development of renewable energy in China and the adjustment of energy structure. The successful operation of the 300kW marine tidal current generator set into the sea is an advantage of United Energy in the development of the National Key Laboratory of Tidal Energy Power Technology of the National Energy Administration. With the support of the State Oceanic Administration's Special Fund for Marine Renewable Energy Research, it actively integrates into the overall situation of national energy innovation and development, focuses on green development, persists in innovation-driven, strengthens technology leadership, and boldly pursues strategic, forward-looking, comprehensive innovation in the field of ocean energy. , The representative results achieved.
In the future, United Power will thoroughly implement the strategy of green development of the National Energy Group. Adhering to innovation is the first driving force for development, bringing together first-rate talents, building first-class products, and providing strategic support for China's clean energy development in the new era.
