    Univ Jiangsu Science & Tech Files Chinese Patent Application for Offshore Wind Power Device Control System and Model Predictive Control Method


    October 6, 2022 - Shipping and Marine Patent News

     

      Beijing, Oct. 5 -- Univ Jiangsu Science & Tech has filed a patent application for offshore wind power device control system and model predictive control method. This invention was developed by Li Tai, Xu Chenglong, Zhao Li, Zeng Qingjun, Zhu Zhiyu, Qian Huimin and Wang Leqiu.

      The patent application number is CN202111433040 20211129. The patent publication number is CN114024340 (A). International Patent Classification codes are H02J3/18, H02J3/38 and H02M5/458. Cooperative Patent Classification codes are H02J3/18 (CN), H02J3/38 (CN), H02M5/458 (CN) and H02J2300/28 (CN).

      According to the abstract released by the State Intellectual Property Office of China: "The invention discloses an offshore wind power device control system and a model predictive control method. According to an offshore wind power plant-side current converter, dynamic matrix model predictive control is adopted to replace traditional PI control so as to improve disturbance resistance and interference resistance of the system and solve the problem that PI parameters are difficult to adjust, a pigeon swarm algorithm is adopted in a rolling optimization link, therefore, the control quantity is optimized, and the response speed of the system is improved. According to a grid-side current converter, finite set model predictive control is adopted, a quadratic function is adopted as a cost function, the minimum value of the cost function is solved, a switching state enabling the cost function to be minimum is selected to generate a switching signal; the switching signal acts on the grid-side converter, and controls the on-off of the grid-side converter. Compared with traditional double-closed-loop PI control, the control structure is relatively simple, an SVPWM modulation process is omitted, and the dynamic performance and the steady-state performance are better."
