关于海洋能源的介绍，里面有来发海洋能源的现状、海洋能源的利弊、海洋能源的应用，里面有波浪能、潮汐能(sea resources with application and classification)

读写取美国地球物理协会标准SEG-Y格式数据，用于石油地球物理勘探的数据交换(it can read and write SEG Y format seismic data, this format is used for seismic data exchange)

读取segy文件后，用于绘制单炮记录等的图像(After reading the segy file, it is used to draw images of single shot records.)

用于计算位场数据的一阶或二阶水平方向导数，一般水平导数用于边界的识别。(The data used to calculate the potential field of a first-order or second-order horizontal directional derivative, the derivative of the general level of identification for border.)

直流断路器 pscad DEMO 可以使用(DC BREAKER DC circuit breaker)

有源滤波器，用于过滤负载谐波电流和补偿无功功率，使得输电线路上的电流为基波分量。(Active power filter (APF) is used to filter load harmonic current and compensate reactive power, so that the current on the transmission line is the fundamental component.)

虚拟同步发电机并网仿真，能够实现虚拟电阻进行限流(Virtual synchronous generator network simulation can realize virtual resistance current limiting)

说明：  simulink PMSM 三相逆变器电压单闭环控制，DC-AC-DC-AC(simulink PMSM DC-AC-DC-AC)

说明：  先dq变换然后构建电压外环电流内环的双闭环系统，实现了statcom的前馈解耦控制。可以解决大负载投入的电压降落问题。(First, dq transform is used to construct the double closed-loop system of voltage outer loop and current inner loop, which realizes the feedforward decoupling control of STATCOM. It can solve the voltage drop problem of large load input.)
