Abstract
Based on the power quality data obtained from the open sea test of tidal current power generation in China, the analysis method of power interval division is proposed in this paper. The power interval is divided according to the rated power of the device, the power quality data of each power interval is counted, the power quality characteristics of each power interval are analyzed independently, and the causes of the power quality problems and the influence on the power grid after the grid connection are described. The power interval division method can improve the accuracy of power quality characteristics analysis of tidal current energy generation devices, and help to find out the causes of power quality problems. The method provides the basis for the optimization and upgrading, and the refined evaluation of power quality of tidal current power generation devices.
