On July 5, the world's first 18-20MW wind storage and load grid unit was launched in Shantou, China. Zhao Zhitao, Deputy Mayor of Shantou Municipal People's Government, Qiao Yinping, Secretary of the Party Committee and Chairman of Shanghai Electric Wind Power Group Co., Ltd. (hereinafter referred to as "Electric Wind Power", stock code: 688660), and Li Gungwu, Member of the Party Committee and Deputy General Manager of Guangdong Branch of China Datang Group Co., Ltd., attended the ceremony and delivered speeches.
Based on more than 10 years of offshore operation experience, Electric Wind Power demonstrates the strength of Poseidon "Double Star" with differentiated products, which can match the optimal model according to different wind speeds and sea conditions. The two units that have come off the assembly line are the world's first 18-20MW wind storage and load grid unit - EW18~20-260, and the king of medium and low wind speed - EW14.0-270.
Under the wind storage and load network mode, the Poseidon product matrix is constructed with differentiated products
The two units of Electric Wind Power that rolled off the assembly line in Shantou are both products of the Poseidon platform, and both follow the mature offshore semi-direct drive technology route.
Among them, the launch of the world's first 18-20MW wind storage and load grid unit is a key step for Electric Wind Power to further build a Poseidon product matrix with differentiated products, and to undertake and serve the national strategy with customized product solutions.
With the extensive development of wind farms in the deep sea base, the local proportion of new energy will increase significantly, and more stringent requirements will be put forward for power grid security. At present, distributed energy storage and grid-building technology have become the most urgent technical problems in the industry.
The third-generation unit of the Poseidon platform can realize the decentralized energy storage configuration of "one machine and one storage" and realize the peak regulation capacity of the power grid; At the same time, it is equipped with the latest grid-building wind turbine technology developed by Electric Wind Power, which can realize the development of wind farms under local weak power grids, and has more friendly grid adaptability, providing strong support for the utilization of offshore wind power in multiple scenarios such as offshore island weak grid power supply, distributed sea wind hydrogen production, flexible direct transmission, low-frequency power transmission, and floating wind turbines in the future.
The so-called wind storage and load network is an operation mode that includes the overall solution of "wind power, energy storage, load and power grid". This model can effectively solve the pain points faced by the wind power industry such as consumption difficulties, poor stability, and low level of intelligence, and make the energy system more flexible and controllable through the organic integration of comprehensive energy elements, and can realize the safe and stable control of weak power grids and even off-grid systems, so as to ensure the efficient use of energy.
Wind: Wind energy and wind turbines are the main energy sources of the power system with a high proportion of wind power, which are bound to be fluctuating, intermittent and random due to the uncontrollable input of natural energy.
Storage: The distributed energy storage power supply solution can meet the requirements of new energy supporting energy storage, and provide backup power for the main control and yaw system of wind turbines, so as to enhance the safety function of wind turbines and realize the flexible allocation of energy supply and demand.
Load: that is, the electrical load, which is the actual consumer of electric energy. The end consumers of the power grid, such as industrial power consumption, lighting and charging piles in the park, as well as isolated island discrete grid systems, are equipped with an energy management platform that can intelligently couple multiple energy sources for power generation.
Grid: Through voltage source control and self-synchronous power grid characteristics, the new product can perfectly give full play to the technical advantages of voltage construction, inertia support and primary frequency modulation of grid-building fans, and can realize high-end functions such as safe and stable control of weak power grid and even off-grid system, on-grid and off-grid switching, and black start of wind storage.
According to reports, the new product adopts full-dimensional coordinated control technology, fully integrates electromechanical control and storage, realizes the function of the whole network, and perfectly releases the potential of transient voltage support, frequency response, weak grid tolerance, oscillation suppression, etc., around the grid-connected and off-grid solution, it can cover a variety of application scenarios such as large energy base, DC/low-frequency transmission, hydrogen production system, isolated grid operation and black start, and support customers to achieve maximum value with flexible grid-connected technology.
Aiming for "high returns" and focusing on "high reliability"
Before 2020, Electric Wind Power started the pre-research work of the offshore semi-direct drive technology route, and released the first offshore semi-direct drive unit in October 2020. Combined with the development and operation experience of the first unit, the first 8.5MW product of the semi-direct drive Poseidon platform was released in 2021. Up to now, the third-generation Poseidon products have been rolled off the production line, applying the latest generation of highly integrated semi-direct drive drive chain technology of electric wind power, integrating more than ten years of experience in offshore wind turbine design, operation and maintenance of offshore wind turbines, aiming at "high profit" and focusing on "high reliability", and fully covering all sea areas in China. After the wind turbine is completed off the production line, it is planned to stand in the coastal test wind farm for further operation test and verification.
The Poseidon platform inherits the mature blade design of electric wind power, reliable pitch and yaw system, efficient and low-energy cooling system, and comprehensive and optimal electrical system. In terms of innovative design in carbon fiber blades, double TRB main bearing design, three-phase medium-speed permanent magnet synchronous generator, compact drive chain structure, etc., and according to the wind resource endowment and marine geological conditions in different sea areas, we provide the best solutions suitable for the local area.
Steady and far-reaching, quality to create the future. The launch of the "Double Star" is an important manifestation of the commitment of Electric Wind Power to customers to fulfill the overall solution of "high reliability and reliability". Electric Wind Power said that the company will continue to pay tribute to the future with quality, continue to create core value for customers, provide customers with excellent services, and help Shantou and the offshore wind power industry move towards high-quality development with steadily iterated products and continuously optimized services, inject endogenous power into the cultivation and development of new quality productivity, and actively serve the national strategy.
