It is mainly used as the prime mover to drive all kinds of production equipment. Therefore, the position of the steam turbine in the industrial production is self-evident. With the development of modern industry, the steam turbine is developing in the direction of large scale, high speed and automation, and the relation between the steam turbine and other production equipments is more and more close. Therefore, once the turbine fails and stops working, it will lead to the stagnation of the whole production process and cause incalculable economic losses. Obviously, the mechanical fault diagnosis has the quite significance in the engineering practice, it even becomes a kind of independent discipline category gradually. This paper starts from the large-scale equipment of steam turbine. First introduced the history of the fault diagnosis of steam turbine, and then the main analysis methods were introduced to turbine fault classification and fault parameters, according to the actual situation of the nuclear power plant, designed a fault diagnosis system, the specific principles to explain in the turbine fault diagnosis technology in the practical application.
