Three methods of fast stability calculation are considered for on-line monitoring of power system stability. From practical viewpoints, method (1) requires too long a computing time; method (2) also requires too long a preparation time but the on-line computing time is short. The disadvantage of method (3) is that the threshold value cannot be calculated precisely and a long computing time is required for on-line calculation of swing curve. A fast transient stability calculation method is proposed which does not use numerical integration but uses Taylor series type swing curve and energy function. According to simulation study, the proposed method becomes more advantageous as the size of power system to be analyzed increases. More precisely, computing time of the proposed method is about 10% of that of the reference method and the calculation accuracy is about the same. 11 refs.
