Problems solved by technology

In the use stage of the turbogenerator, the statistical results of the available coefficient of the turbogenerator can be determined through the statistical analysis of the operating data of the turbogenerator, but the available coefficient of the turbogenerator design cannot be determined in the design stage
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 availability factor

Embodiment

[0047] Such as figure 1 Shown is the functional block diagram of the turbogenerator system. A certain type of 600MW turbogenerator adopts a brushless excitation system without an auxiliary exciter. Composed of water cooling system and monitoring and protection system, figure 1 The arrows in represent the interaction relationship and the input and output of the power generation system, and the arrows connect the generator body with the related systems.

[0048] Such as figure 2 Shown, be the flow chart of the method adopted in the present invention, the design method of turbogenerator high availability 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, calcul...

Abstract

The invention relates to a design method for high availability 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 availability AP1 of the turbonator body; (3) determining the availability AP2 of a turbonator excitation system; (4) determining the availability AP3 of a turbonator bearing oil and sealing oil system; (5) determining the availability AP4 of a turbonator internal hydrogen cooling and internal water cooling system; (6) determining the availability AP5 of a turbonator monitoring and protecting system; (7) determining a planned outage factor (POF) of the turbonator; (8) calculating available factor (AF) of the turbonator; (9) evaluating the result; and (10) improving the design. The invention has the advantages of having the capability of quantitative calculation and quantitative evaluation and effective improvement of the AF of the turbonator.

Description

technical field [0001] The invention relates to a high-availability design method and an evaluation method of a turbo-generator, which is applied to the design calculation and improvement of the availability of the turbo-generator, and belongs to the technical field of the turbo-generator. Background technique [0002] A turbogenerator is composed of a generator body, an excitation system, a bearing lubricating oil and sealing oil system, a hydrogen internal cooling system and a water internal cooling system, and a monitoring and protection system. The index for evaluating the availability of a turbogenerator is the availability factor. In the use stage of the turbogenerator, the statistical results of the available coefficient of the turbogenerator can be determined through the statistical analysis of the operating data of the turbogenerator, but the available coefficient of the turbogenerator design cannot be determined in the design stage. The existing turbogenerator desi...
