Study of Seismic Damage to Power Generation and Distribution Network

Utilization of hydraulic potential energy and thermal energy by construction of power plants which are generally situated at some remote locations and are far from consumption ports, necessiate the establishment of transmission system (lines) and substations. Due to vastness of regions and existence of different conditions attributed to the ground, the outbreak of various incidents, such as earthquake is probable. Although the damages , inflicted upon power utility system are not significant, but interruption in production of electrical energy and transmission of this energy at any moment and profound investments , requires a special attention to observe the behavior and responses of current seismic forces. Studying of destructive effects of recent earthquake on the power system (generation, substation and transmission) in Iran (Bam city-2004), Philippines and other countries, proved the significant of the above mentioned studies. Concerning the importance of utilization of energy, improving the current situation, increasing the safety level for availability of electrical equipment and future projects, it is necessary to take some procedures into consideration to prevent or lessen the destructive consequences of earthquakes. This research work concentrate on the study about “seismic retrofit planning methods, seismic upgrading design for power network facilities based on the foreseen seismic risk assessment of electrical power generation and distribution systems.
