A New Traj ectory Sensitivity Computing Method Based on Measured Traj ectories in Multi-machine Power System
摘要
Abstract
Traj ectory sensitivity is an important tool for power system dynamic security analysis.A new traj ectory sensitivity calculating method based on traj ectories for a multi-machine power system is proposed.The mathematical relationship between traj ectory sensitivity and traj ectory in a power system is constructed based on detailed power system models,and the traj ectory sensitivity calculating method based on traj ectory is proposed,with the sensitivity of traj ectory to parameters directly obtained by the convolution of trajectories alone.The New England 10-generator 39-bus machine system simulation studies show that the proposed traj ectory sensitivity calculating method is valid.The traj ectory-based traj ectory sensitivity calculating method has revealed the physical association between the trajectory sensitivity and trajectory in power system.And the accuracy of calculating the output is independent of the validity of parameters,providing a new measure for traj ectory-based power system dynamic security assessment.关键词
