Reliability analysis of auxiliary service system of steam power plant in Iran

In this paper, the auxiliary service system of the NEKA steam power plant in the North of Iran is analyzed from the reliability point of view. Reliability of auxiliary equipment in a steam power plant directly affects the performance of plant; therefore, the design should be done with special consideration to the auxiliary system. This consideration should include having adequate reserve sources and additional plants of power flow. Usually reliability analysis in large industrial plants needs special consideration. This is due to the complexity and usage of several peripheral devices that prompt consideration of various factors not to be limited to evaluation of a simple connection between the existing equipment. However, the failure of peripheral devices should also be considered as they con affect the overall performance of the system. In addition, before making any analytical studies, a through quantitative study should be done and the failure for different equipment should be defined
