Studies on seismic function failure of electric power supply system

In this paper, seismic function failure analysis method of electric power supply system is introduced, which study not only the electric equipment linked probability when an earthquake occurs, but also the power flow analysis. Because the electrical power failure can be caused by disconnection and abnormal load flow in a power transmission network, the seismic load flow analysis methods of power supply system are studied specially. All of above will be a basis in research of anti-earthquake analysis, function assessment and damage mitigation for electric power supply system.
