Latest Patents

One of his latest patents is titled "Method and system for adaptive single-phase reclosing of wind farm AC transmission lines." This invention relates to a method and system for adaptive reclosing of single-phase AC transmission lines in wind power systems. The invention utilizes single-ended electrical quantity to determine the type of fault. After a fault occurs, a signal acquisition device is used to sample the voltage of the fault phase. The obtained voltage is subjected to short-time Fourier transform to extract the amplitude of the fundamental frequency voltage component, and then processed with differential amplification to construct a fault nature identification criterion. Combined with a sliding time window for fault identification, if it is identified as a permanent fault, the reclosing device is locked out; if it is identified as a transient fault, the fault disappearance time is calculated to determine the reclosing time and output the closing signal. This invention is designed for adaptive reclosing after a circuit breaker trips in wind power AC transmission lines.

Another significant patent is the "PLP optimized placement method for a wind farm of plateau-mountain region." This invention provides an optimized PLP placement method for plateau and mountain wind farms. Starting from the outermost wind turbines, it measures turbine parameters. Firstly, the first PLP is installed to safeguard the outermost ones. Then, it combines its parameters with those of the tallest turbine near the center to set up the second PLP, protecting turbines within a connection range. Next, the previous step's parameters and those of the tallest turbine in the vertical area of the first two PLPs' plane are used to install the third PLP, shielding turbines in the area formed by three points. This process is repeated until the whole farm is covered. Many cases prove its reliability, economy, and suitability for wide application in optimizing PLP placement.
