Based on the unsteady compressible three-dimensional N-S equations and standard k-turbulent model, the travel process was simulated used the finite volume method. The pressure variation mechanism and its spatial-time change characteristic of PSD were analyzed. Meanwhile, the relationship between the pressure of PSD and such influence factors was discussed, as train speed, blockage ratio, the area...
Fuzzy PD controls strategy capturing maximum wind energy is presented according to the variable of wind. Fuzzy has been widely used because of its nonlinear and stability. However, when it comes to the stable region under capturing maximum wind energy, it becomes fluctuation and brings dangerous to grid. Improving stability and capturing maximum wind energy are the keys of research. Simulation results...
