小波分析属于调和分析，是一种时域、频域分析，具有多分辨率特性，它巧妙地利用非均匀分布上的分辨率通过平移的可变窗口观察非稳信号。

Steady-state harmonics and transient performance of the conventional static synchronous compensator controllers are first investigated. Based on the sensitivity analysis of the STATCOM output power, it is found that the voltage magnitude is more effective than the phase angle in controlling the reactive power output. An analytical approach to harmonic analysis of a STATCOM based on Bessel functions of the first kind is described.

本博士论文首先分析传统静态同步补偿器(Static Synchronous Compensator， STATCOM)控制器的优缺点，利用对静态同步补偿器输出功率的灵敏度分析，得知要控制补偿器输出虚功大小时，直接对静态同步补偿器输出电压大小作控制，会比对相角作控制来得有效。

Using harmonic analysis of the calculated tidal level and current, the distributions of co-tidal lines for K1, O1, M2 and S2 are obtained, whose maximum amplitudes can reach 112 cm, 96 cm, 50 cm and 15 cm, respectively. The distribution of the maximum probable current velocities in Qinzhou Bay is basically the same as that of isobaths, and the maximum probable current velocity can reach 200cms^(-1) nearby the Longmen Harbor. It is concluded by the analysis of K1 and M2 tidal current ellipses that the flow is rotating at the mouth of the bay, while its retilinear flow is in the nearshore area, estuaries and channels. The distributions of the major axes are closely related to the topography, and the rotation directions of both constituents are clockwise.

根据模拟结果计算得到了较以往更为精细的钦州湾K1、O1、M2、S2分潮的同潮图，潮汐最大振幅分别为112、96、50和15cm；最大可能流速的分布基本与等深线一致，龙门港附近最大可能潮流流速可达200cms^(-1)；钦州湾的外湾口海域开阔，一般为旋转流，近岸海区及水道、河口等多为往复流，K1和M2分潮流椭圆长轴的分布与地形密切相关，旋转方向均为顺时针，流速极值出现在龙门港区。
