Problems solved by technology

In the use stage of the turbogenerator, the statistical results of the forced outage rate of the turbogenerator in the use stage can be determined through the statistical analysis of the operating data of the turbogenerator, but the forced outage rate of the turbogenerator design cannot be determined in the design stage. luck
The existing turbogenerator design method can judge whether the strength and vibration design of the turbogenerator components are safe through the mechanical calculation, strength calculation and vibration calculation of the turbogenerator. Design value of generator forced outage rate

Embodiment

[0047] Such as figure 1 Shown is the reliability block diagram of the turbo-generator system. A certain type of 600MW turbo-generator adopts a brushless excitation system without auxiliary exciter. Oil), cooling system (hydrogen internal cooling and water internal cooling), monitoring and protection system, its reliability block diagram is as follows figure 1 Show.

[0048] Such as figure 2 Shown, be the flow chart of the method adopted in the present invention, the design method of high reliability of steam turbine generator and evaluation method thereof are:

[0049]The strength design of this type of 600MW turbogenerator is all qualified, calculated from Table 1, K 1 = 0; the rotor vibration design is qualified, the stator vibration design and the fan vibration design are not carried out, and K is calculated by looking up Table 2 2 =0+0.0006+0.0006=0.0012; no life design is carried out, calculated from table 3, K 3 =0.0006+0.0006+0.0006=0.0018. Considering the above ...

Abstract

The invention relates to a design method for high reliability of a turbonator and an evaluation method thereof, and the invention is characterized by comprising the following concrete steps: (1) determining a design colligation coefficient Ak; (2) determining the operation reliability AO1 of the turbonator body; (3) determining the operation reliability AO2 of a turbonator excitation system; (4) determining the operation reliability AO3 of a turbonator oil system; (5) determining the operation reliability AO4 of a turbonator cooling system; (6) determining the operation reliability AO5 of a turbonator monitoring and protecting system; (7) determining a correction factor ki of a planned correction type of the turbonator; (8) calculating forced outage rate (FOR) of the turbonator; (9) evaluating the result; and (10) improving the design. The invention has the advantages of realizing reliable designing and improvement of the turbonator, and achieving the technical effect of lowering the FOR to improve the reliability.

Description

technical field [0001] The invention relates to a high-reliability design method of a turbogenerator and an evaluation method thereof, which are applied to the design calculation and improvement of the reliability of the turbogenerator, and belong to the technical field of the turbogenerator. Background technique [0002] Turbogenerator consists of generator body, excitation system, oil system (bearing lubricating oil and sealing oil), cooling system (hydrogen internal cooling and water internal cooling), monitoring and protection system, and is an index for evaluating the reliability of turbogenerators is the forced outage rate. In the use stage of the turbogenerator, the statistical results of the forced outage rate of the turbogenerator in the use stage can be determined through the statistical analysis of the operating data of the turbogenerator, but the forced outage rate of the turbogenerator design cannot be determined in the design stage. luck rate. The existing tu...
