Study on Earthquake Resistance of Electric Power System Based on System Reliability

This the paper discusses the seismic reliability analysis of electric power system. In the paper, through the analysis of properties of the power system and power network system characteristics, some suggestions are put forward that it is not only need to consider site selection, power substations buildings, power structure analysis in individually in the seismic reliability analysis of power system, but to guarantee the reliability of the power system. Therefore it is necessary to ensure the connecting reliability from the plants to the users (substations). Based on this, it can be done the electric power system the seismic design, maintenance and modification. For a power network system, the seismic reliability has been analyzed in this paper, and the practical conclusions were obtained.
