| The development of electric power is the base of economic development. The diversification of requirement on electronical power market, ask for more and more large power units to join in peak shaving. To ensure these units running in secure state, and to upgrade the economic benefit, it' s necessary to supervise the life consume of power unit's rotator online.We use the method of finite element analysis to find the most dangerous section of the rotator. Through setting up a model of rotator, calculating the temperature and stress field of rotator, we get the section. Then we supervise the section online, calculate the practical fatigue life loss and creep life loss. This gives a convenient utility to economical production of the units.The paper discussed the method of finite element analysis, the theory of life consume, supervise system online, and etc.The supervise system is putted into use on the No. 1 power unit of JiaXing Power Plant. |
