在时间上使用隐式有限差分法,空间上使用后向差分法,对耦合波方程组离散化,进而对受激布里渊散射的能量反射率和产生SBS的阈值能量进行数值模拟。(Begin with the coupled wave equations which describe the interactions of the pump, the sound and the Stokes wave in the process of SBS. The equations are simplified according practical conditions, and one-dimension theoretical models are obtained aiming at unfocused pump as well as focused pump. The coupled equations are turned discrete using the method of implicit finite difference in terms of time and backward difference in terms of space.)

Hybrid PV-wind generation shows higher
availability as compared to PV or wind alone. For rural
electrifications, researches are focused on hybrid power system
which provides sustainable power. The variable voltage and
frequency of the self excited induction generator (SEIG) is
rectified through Vienna rectifier (three switches) to the required
D.C voltage level and fed to common D.C bus. The variable output
voltage of PV module is controlled by DC/DC converter using
proposed fuzzy logic controller and fed to common D.C bus. The
DC bus collects the total power from the wind and photovoltaic
system and used to charge the battery as well as to supply the A.C
loads through inverter. A dynamic mathematical model and
MATLAB simulations for the entire scheme is presented. Results
from the simulations and experimental tests bring out the
suitability of the proposed hybrid scheme in remote areas.
