Seismic Performance Evaluation of Electric Power Systems and Modeling of their Post-Earthquake Restoration

Seismic Performance Evaluation of Electric Power Systems and Modeling of their Post-Earthquake Restoration

Power disruption caused by devastating earthquakes or other hazards may result to huge direct and indirect losses in the societies. This raises the urge to develop techniques for the simulation of an incident associated with power disruption. This series of studies aimed at the seismic scenario simulation and risk assessment of electric power systems. This year, the inventory of the Taiwan Power Company’s(Taipower) system has been updated, which include the data for power flow analysis(with newly-installed or upgraded facilities), the locations of 345kV transmission towers and the parameters for equipment fragility. The losses in power supply caused by the damage in 345kV transmission lines due to various fault ruptures have been estimated. Finally, an approach to simulate the restoration of power systems by using the Monte Carlo method has been proposed to investigate the serviceability of Taipower’s system in post-earthquake conditions.
