The theory and application is explained in this paper. Software XMGREDIT5 matching ELCIRC is used to generate unstructured grid, and is considered fit for ocean but rivers. Tidal current is simulated and validated well, and sensitivity of current structure to bathymetry is visible. Affection of wind is qualitatively analyzed here. At the same time the model is improved on as required, like the tidal open boundary which could choose not only long period harmonic constant but also short period harmonic constant and tidal level, and multi-point results and flow field data could be exported effectively with binary results.

Points out that the switching frequency、the input inductance and the output power all have great contribution to the input-current THD. When the output power goes up, the input current harmonic content keeps almost constant, thus the THD goes down.

指出开关频率、输入电感和输出功率对输入电流THD有显著影响，发现整流器输出功率增加时，输入电流谐波含量基本不变，从而输入电流THD减小。

Not only it can display all stable state parameter, but also the load increase quickly, load decrease quickly, voltage, current, frequency curve, voltage curve, current harmonic curve and harmonic content.

The stress was the study of the new methods of calculation the harmonic voltage and the harmonic current, and a new concept of filter ratio to evaluate the actual effect of single harmonic filter was raised considering the background harmonics. As well, the calculation mode of the single harmonic filter was also given based on the concept of filter ratio; it can offer effect data to evaluate the actual filter ratio of the single harmonic filter. At the same time, a method of designing the single harmonic filter was given, too, considering the background harmonics of the power system. In this paper, both the computer analysis and the proven had been done. And the result was shown to be that the voltage aberration and the harmonic current were decreased, and that the actual filter ratio of single harmonic filter was raised. The reason that we must consider the background harmonics when designing a single harmonic filter was also expatiated in this paper.
