大型风电场接入电网的稳定性问题研究,希望对大家有点启发( the problems of Large wind farms connected to the grid stability)

说明：  设计了燃料电池的分布式发电系统，将分布式发电系统与电网进行并联。并对其进行了仿真。(Has designed fuel cell s distributional generating system, carries on parallel the distributional generating system and the electrical network. And has carried on the simulation to it. )

用于PSCAD的元件库模型，可以用于搭建柔性直流输电的MMC模型，使用此元件库更加方便，实用。(For the PSCAD component library model, can be used to build flexible DC transmission of the MMC model, the use of this component library more convenient and practical.)

说明：  实现了以输出电压及其一阶导数为状态变量的无差拍控制的仿真(Realized by the output voltage and its first order derivative of state variable simulation of deadbeat control)

vumat 代码，用于abaqus explicit 金属塑性伤害模拟(vumat subrountine for abaqus explicit ,the hill parameter is to set 0.5 and 1.5 by default.)

油田开发效果评价，考虑非均质性的流管法！输入相渗曲线、高压物性资料、渗透率伽马分布等，即可进行油田水驱开发效果评价！(Oilfield development effect assessment, consider the heterogeneity of the flow tube! Input relative permeability curves, PVT data, the penetration of the gamma distribution, oil field water flooding effect evaluation can be carried out!)

地震剖面显示,主要用于石油地震勘探中地震剖面的显示，可以显示波形、变面积和变密度剖面(Seismic data display，mostly used for seismic data processing,it can display waveform, variable area and variable density)

电力系统分析，小扰动分析，特征值计算，柔性直流输电(Power system analysis, small disturbance analysis, eigenvalue calculation, flexible DC transmission)

说明：  simulink搭建的全桥整流+buck电路，实现AC到DC，然后DC到DC的变换，其中全桥为SPWM控制。(Simulink built a full bridge rectifier +buck circuit, AC to DC, and then DC to DC transform, in which the whole bridge is SPWM control.)

说明：  对于电力系统网络，当其发生小电流接地故障时，分析其特性(For power system network, its characteristics are analyzed when a small current grounding fault occurs)
