A new chapter in human deep-sea energy development! The world's largest floating wind power platform "Mingyang Tiancheng" is officially put into operation



On December 11, the world's largest floating wind power platform "Mingyang Tiancheng" was officially put into operation in Yangjiang, Guangdong, opening a new chapter for human exploration of deep-sea energy.
                                                  

"Mingyang Tiancheng" was independently developed by Mingyang Group. It is the world's first to carry two 8.3 MW offshore wind turbines on a floating foundation, with a total installed capacity of 16.6 MW. It is currently the world's largest floating wind power platform. The platform has a total displacement of about 15,000 tons. It is put into operation at the Mingyang Yangjiang Qingzhou Si offshore wind farm, about 70 kilometers offshore and 45 meters deep. It is expected to provide about 54 million kWh of green electricity each year, which can meet the daily electricity needs of 30,000 households of three for one year.


Different from the traditional wind turbine structure, the two wind turbines of "Mingyang Tiancheng" stand side by side, and the two wind rotors rotate in opposite directions. This design increases the wind speed in the middle area of the impeller, and the electric energy converted from the kinetic energy of the air also increases accordingly, which increases the power generation by 4.29% compared with a single large wind turbine with the same wind sweeping area. At the same time, this design also brings new challenges to debugging.


To ensure that both wind turbines can operate smoothly and smoothly, and to eliminate deviations in the operation of the two wind turbines, so that the two "mirror" wind turbines can operate "simultaneously", "at the same frequency" and "in the same state", the "Ming Yang Tiancheng" is equipped with three controllers. Two of the controllers adjust the speed, torque, etc. of their corresponding main engines and wind rotors respectively, and the central controller is responsible for the balance and coordination of the two main engines and two wind rotors, thereby achieving the coordination of the entire wind power platform.

Rigorous testing work runs through the entire process of wind turbine development and installation, making new explorations for the key debugging technologies of subsequent deep-sea floating wind power platforms. The "Mingyang Tiancheng" has been fully verified in the software environment of all working conditions and the hardware-in-the-loop environment of characteristic working conditions. It can simulate the operation of wind power platforms and hardware in real environments or partially real environments, and can effectively ensure the reliability of wind turbines in actual applications. After the installation of the offshore position is completed, in the absence of external power support, the "Mingyang Tiancheng" uses the jointly pioneered "black start" technology - using its own energy and control system to complete the start-up and operation of the wind turbine, thereby achieving idling debugging.


In addition, the "Ming Yang Tiancheng" also carried out tests on the island mode of small-power units, verifying the autonomous survivability and stability of the wind power platform when operating independently without the power grid.

After being put into operation, the operating parameters of "Mingyang Tiancheng" showed that its overall six-degree-of-freedom motion response was consistent with the design value; at the same time, the data collected by the cables, mooring system and other monitoring systems showed that each system was operating stably within the design allowable range. Subsequently, Mingyang will complete various operation tests as planned and compare them with the design parameters to ensure that the entire wind power platform operates in good condition.
The official operation of "Ming Yang Tiancheng" not only promoted another major breakthrough in the field of floating wind power, realizing the expansion of the exploitable scale of marine energy through equipment innovation, but also promoted the interconnection and mutual assistance of various energy modes, and helped explore the three-dimensional integrated development of marine energy to advance into the deep sea, realize integration in space, function and structure, and continuously extend the boundaries of offshore wind power development, contributing wisdom and strength to the key green new quality productivity of developing the deep blue sea and building a strong marine dream.
