大容量集成式储能脉冲发电机关键技术研究

High capacity pulsed-power generator intergrated with enery storage unit,the rotor of which is used as flywheel, can provide high pulsed power for special loads via high capacity pulsed-power converter. Taking into account its structure and operating conditions particularity, the critical issues of design, modeling and analysis of pulsed-power generator system should be studied profoundly. .Aiming at the special power supply demand of the pulsed-power converter loads, trade study on multiple sets of multi-phase winding layouts of pulsed-power generator will be conducted to obtain a reasonable result. Taking into account the difference of operation condition between pulsed-power generator and normal one, special electromagnetic design will be developed as well. Then, its detailed mathematical model will be established to show electromagnetic coupling between multiple sets of multi-phase windings and eddy-current circuits, and method to get electormagnetic parameters via theoretical analysis and finite-element simulation will be studied as well. On the basis of these works,the discrete numerical algorithm of the pulsed-power generator will be studied profoundly, in order to be used in RT-LAB. Hereafter, the system simulation codes will be constructed, and impacts of different recifier modes on system will be evaluated by analitical method and simulation to adopt better one. Finally, the validity and accuracy of proposed techniques will be checked by simulation studies and experimental tests..The above research works can be taken as the foundation of basic theory and key techniques for the application of high capacity pulsed-power generator integrated with energy storage unit on the mobile platform.
