description | Based on the single-machine infinite bus system, the validity of trajectory sensitivity calculation by convolution method is deeply analyzed, which provides support for using wide area measurement system to calculate the trajectory sensitivity and improves the level of dynamic safety analysis in power system. Theoretical analysis shows that, the relationship between the track sensitivity and the track will not change by changing generator models. Dynamic simulation is carried out on the basis of theoretical analysis. The simulation results show that different models can simulate the almost consistent dynamic track. The above research shows that the convolution method for calculating the track sensitivity is not affected by the system model. An index is established to evaluate the accuracy of the convolution method for calculating the trajectory sensitivity. By changing the generator model, the disturbance amount and the initial operation state, the dynamic simulation trajectory is traversed. The results show that the convolution method for calculating the trajectory sensitivity in the single-machine infinite bus system has high reliability, the results of convolution method for calculating the trajectory sensitivity in the actual engineering are of high reference value. |
