| Abstract: | In this paper,the seismic function failure analysis method of electric power supply system is introduced.Because the electrical power failure can be caused by disconnectivity and abnormal load flow in power transmission networks,the power electric flow is studied,and the system flow load control method is also discussed.Especially,the seismic sensitivity analysis model is studied and the decoupled security enhancement algorithm(DSEA) is employed to study the power flow control problems.Finally,an example is... |
