In the system of the PV grid-connected generation, because of the dispersion of the PV panel, difference of the sun radiation condition and the shadow of a part of the PV panel, they will cause the serious loss of energy for the parallel PV panel. In order to overcoming energy loss and raise the efficiency of the PV system, a new maximum power point tracking method called distributed variable step...
The refractive index of salt water changes corresponding to the variation of salinity. Based on a differential refractometer, the salinity can be measured due to beam deviation, and the influence of temperature on the measurement results is reduced effectively. Beam deviation caused by salinity change is detected by a fiber-optic array and recorded by a charge-coupled device. According to the Gauss...
