| Abstract |
Conditions for rational construction of valve model for converter analysis are formulated. A new concept of establishing of a valve model is proposed. The model is represented by a set of states. Thus a simulation of both normal and fault operation is possible only by increment of number of valve states. Each of the states is associated with an equivalent circuit. To built up those circuits only the device manufacturer specification data are necessary. If one of numerical implicit integrated method is applied both invariant topology of converter and stability of numerical solution is assured. The principle of method is presented on two examples. Fïrst, turn off thyristor process in a simple RL circuit is simulated. Second, analysis of inverter driven by DC chopper is presented. The simulation waveforms obtained on a personal computer for normal and fault operation are shown. Given its efficiency the method for converter CAD programs can be recommended. |
