Therefore,it is not convenient to study the performance of such system profoundly by analytical method. Firstly,difference of winding layout between this machine and traditional 12- phase machine was described briefly;

then,mathematical model was established, and the complicated electromagnetic coupling relationship inside windings of this machine was illuminated. Here- after,its simulation codes were developed by implicit trapezoid iterative method. The block diagram of the exciter controller was described briefly, and exciter speed was locked with the speed of main generator by speed synchronous algorithm. Finally,the simulation codes of the whole system were developed in PSCAD/EMTDC. A load condition was simulated,in which the duty ratio of inverter was constant. The accuracy of the model and the validity of the proposed method are confirmed by comparisons between the experimental test results and simulation results. Key words: energy storage system;
