| Abstract: | Based on linearization characteristics method and symmetrical component method,the Visual Basic is used for programming of hydropower station short circuit calculation.The program involves mainly two states: transient short circuit and steady short circuit,which can obtain the symmetrical components(positive,negative and zero-sequence) of voltage and current,distributed on each branch circuit under various short circuit types and also can express them in phasor form(complex number) to meet actual requirements of the relay protection and the electric secondary specialty.Meanwhile,a comment on short circuit algorithm and some local optimization are given for computer programming. |
