Inquiry (采购产品): generator Hello, I am the last year student of Electrical and Control Engineering at Gdansk University of Technology (Poland). Now I am finishing my Master thesis at Institute National Polytechnique de Grenoble (France). My thesis is about modeling the electric network on the aircraft. I am working in SABER software. To finish my work I need the model of a synchronous generator. Can I ask you for help? What can I do now for you is to put the information in my thesis about the source of the model so I will mention about your company. Thank you for your help. Przemyslaw Kurowski I need the synchronous generator which will work at 400 Hz. My required power is 250 kVA, but I can also use the other model in per unit systems. The SABER software require the following parameters : rs = (ohms) resistance of stator windings Bm = (Nm*/rad/sec) motor damping constant j= (kg*m2) motor inertia p = (poles) number of poles and also the following parameters for one of the systems: - for per unit systems: v_base = , w_base = , kva = , xls = stator leakage reactance X0 = 0 sequence reactance Xd = d-axis synchronous reactance Xq = q-axis synchronous reactance Xpd = Transient d-axis synchronous reactance Xpq = Transient q-axis synchronous reactance Xppd = Subtransient d-axis synchronous reactance Xppq = Subtransient q-axis synchronous reactance Tpd = d-axis transient short ckt time constant Tpqo = q-axis transient short ckt time constant Tppd = d-axis subtransient short ckt time constant Tppq = q-axis subtransient short ckt time constant - or for SI sytem: Lls = (henries) stator winding leakage inductance L0 = (henries) Zero Sequence Reactance Ld = (henries) d-axis synchronous inductance Lq = (henries) q-axis synchronous inductance Lpd = (henries) Transient d-axis synchronous inductance Lppd = (henries) Subtransient d-axis synchronous inductance Lppq = (henries) Subtransient q-axis synchronous inductance Lmd = (henries) d-axis stator magnetization inductance Lmq = (henries) q-axis stator magnetization inductance Lplf = (henries) stator field winding leakage inductance Lplkd = (henries) transient d-axis damper winding leakage inductance Lplkq = (henries) transient q-axis damper winding leakage inductance rfd = (ohms) d-axis field winding resistance rpkd = (ohms) d-axis damper winding resistance rpkq = (ohms) q-axis damper winding resistance **** Hidden Message ***** Przemyslaw Kurowski 38031 FRA Company: INPG E-mail: przemyslaw.kurowski@leg.ensieg.inpg.fr **** Hidden Message ***** przemyslaw.kurowski@leg.ensieg.inpg.fr
