Pojednostavljeni algoritam raËunanja varijablistanja (magnetskog toka, napona i struje) dan jena slici 6. OteæavajuÊa Ëinjenica pri realizacijiprograma je da se poËetni uvjeti pri svakom prijelazuiz jednog u drugo podruËje stalno morajupreraËunavati.A simplified algorithm for the calculation of statevariables (magnetic flux, voltage and current) ispresented in Figure 6. A complicating factor in theimplementation of the program is that the initialconditions at every transition from one region to anothermust constantly be recalculated.PoËetakUËitavanjeparametara sustavaStartLoading systemparametersSlika 6Razvijeni algoritam,pojednostavljenimodelFigure 6Developed algorithm,simplified modelRaËunanje poËetnih uvjeta 01 , U 01 , I 01i koeficijenata a, b i cCalculation of initial conditions 01 , U 01 , I 01and coefficients a, b i cTeæinski koeficijenti:i=1, j=0, k 1 =1, k 2 =0Weighting coefficients:i=1, j=0, k 1 =1, k 2 =0t=T ukt=T ukt=t+ht=t+hRaËunanje magnetskog toka = k 1 (L m1 , 01 , U 01 , I 01 ) + k 2 (L m1 , L m2 , 02 , U 02 , I 02 )Magnetic flux calculation = k 1 (L m1 , 01 , U 01 , I 01 ) + k 2 (L m1 , L m2 , 02 , U 02 , I 02 )NENO||≤ z||≤ zDAYESi=i+1, j=0i=0, j=j+1i=i+1, j=0i=0, j=j+1NEi=1 j=1NENOi=1 j=1NODADAYESYESPreuzimanje novihpoËetnih uvjeta 01 , U 01 , I 01 ikoeficijenata a, b i cPreuzimanje novihpoËetnih uvjeta 02 , U 02 , I 02 ikoeficijenata a, b i cAcceptance of newinitial conditions 01 , U 01 , I 01 andcoefficients a, b i cAcceptance of newinitial conditions 02 , U 02 , I 02 andcoefficients a, b i cNEt≤T promNOt≤T considDAYESPrintanje rezultata:(t), u(t), i c (t), i m (t)Print-out of the results:(t), u(t), i c (t), i m (t)KrajEnd595TokiÊ,A., UglešiÊ, I., NumeriËki proraËun niskofrekvencijskih..., Energija, god. 56(2007), br. 5., str. 584-607TokiÊ, A., UglešiÊ, I.,The Numerical Calculation of..., Energija, vol. 56(2007), No. 5, pp. 584-607
