The VSCF DFIG wind power generation is transient response proceeding, which is influenced by operation characteristics of generator before and after grid connected. A novel S-Function is adopted to describe the mathematic model of DFIG based on state equation. A complete simulation model of VSCF DFIG wind power generation system based on MATLAB/Simulink and SimPowerSystems is established, which can be used to not only simulate subsystems of no-load operation and generation operation, as well as can be used to but also accurate control parameters of DFIG in simulation. The simulation model have excellent transportability, and can be used DFIG of different power rated if only design relevant controller.

变速恒频双馈电机风力发电是一个受并网前后发电机运行状况影响的暂态过程，利用MATLAB的S-Function编写DFIG的仿真程序，然后结合Simulink和SimPowerSystems工具箱，开发了基于S-Function的空载运行和发电运行的变速恒频双馈电机风力发电子系统模型，在仿真过程中可对双馈电机进行精确控制，然后对其进行了系统整合，本文开发的模型具有可移植性，只要再设计相应的控制器，就可应用于不同功率等级的双馈电机风力发电系统。

Cases with renal transplantation were performed with dynamic state CDFIin Ultrasound Dept. of Nan fang Hospital from April, 2005 to October, 2006. Theexamine time is respectively after operation in three days, seven days, one month andthree months. Before operation examine the condition of uropoiesis function such as apair of kidney, ureter, bladder and cardiac function. After operation reexamine thecondition of cardiac function once again, and examine TK detailed and completely:First, using two-dimensional imaging to observe the shape and the volume of the TK.Secondly, using Color Doppler to observe the renal artery and each artery inside theTK. Finally, using pulsed Doppler to measure the peak systolic velocity, enddiastolic velocity and resistance index.
