Modes for Carrying Out the Invention

[0023] To further clarify the purpose, technical concept, and advantages of the embodiments of this application, the technical concept of the embodiments of this application will be described clearly and completely below with reference to the drawings of the embodiments of this application, and it is clear that the embodiments described are a part of the embodiments of this application, not the entirety of the embodiments. Any other embodiments that a person skilled in the art can obtain without creative effort based on the embodiments of this application are all within the scope of protection of this application.

[0024] As hydroelectric power generation units are the core power generation equipment of hydroelectric power plants, regular inspection and maintenance work is necessary to ensure that they can operate normally. Currently, inspections of hydroelectric power generation units in China are often carried out using periodic inspections in accordance with inspection technical standards, and these periodic inspections are divided into Class A, Class B, Class C, and Class D inspections.

[0025] Among these, Class A inspection refers to an inspection method in which a hydroelectric generator is completely disassembled and inspected and repaired in order to maintain, restore, or improve the performance of the equipment.

[0026] A Class B inspection involves partially disassembling a hydroelectric generator system for inspection and repair.

[0027] A Class C inspection involves inspecting, evaluating, repairing, and cleaning equipment where wear and deterioration are regular.

[0028] A Class D inspection is a repair performed to eliminate defects in the main equipment and its associated systems, assuming that the overall operation of the equipment is in good condition.

[0029] Generally, the inspection cycle for Class A inspections is 8 to 12 years, for Class B inspections it is 4 to 7 years, and for Class C inspections it is 1 to 3 years.

[0030] Because factors such as the equipment production quality and operation and maintenance levels of the hydroelectric power generation units at each power plant are not consistent, periodic inspections can result in situations of over-inspection or under-inspection of the units. To solve this problem, each power plant is successively researching the content of condition inspections, and the determination of inspection items for the condition of hydroelectric generators is generally based on an evaluation of the condition of the hydroelectric power generation unit. However, since the evaluation of the current condition is generally based on the unit's condition monitoring system and some other factors, the condition evaluation results are not satisfactory.

[0031] Therefore, the embodiment of the present invention provides a method for evaluating the condition of a hydroelectric power generation unit, and achieves the effect of effectively and accurately evaluating the condition of the hydroelectric power generation unit by analyzing its condition throughout its entire lifecycle.

[0032] According to the embodiments of the present application, an embodiment of a method for evaluating the state of a hydroelectric power generation unit is provided. The steps shown in the flowchart of the drawings may be executed, for example, in a computer system of a set of computer executable instructions. Although the flowchart shows a logical order, in some cases the steps shown or described may be executed in an order different from that shown.

[0033] This embodiment provides a method for evaluating the condition of a hydroelectric power generation unit. Figure 1 is a flowchart of the method for evaluating the condition of a hydroelectric power generation unit according to an embodiment of the present invention. As shown in Figure 1, the process includes the following steps S101 to S103.

[0036] The first dataset shows equipment-related data throughout the entire lifecycle of the hydroelectric power unit being evaluated.

[0037] Step S102: Based on the first dataset, perform a full-life cycle analysis of the hydroelectric power generation unit to be evaluated and obtain the results of the full-life cycle state analysis of the hydroelectric power generation unit to be evaluated.

[0038] Specifically, the first dataset can reflect the equipment status of the hydroelectric power generation unit under evaluation throughout its entire lifecycle. Therefore, based on this first dataset, a full-lifecycle analysis of the hydroelectric power generation unit under evaluation can be performed to obtain the corresponding full-lifecycle state analysis results.

[0039] Step S103: Based on the results of the overall lifecycle state analysis, determine the state evaluation result for the hydroelectric power generation unit being evaluated.

[0040] Specifically, the results of the full lifecycle state analysis can reflect the state of the hydroelectric power generation unit under evaluation throughout its entire lifecycle. Therefore, based on the results of the full lifecycle state analysis obtained, the current state of the hydroelectric power generation unit under evaluation can be further assessed.

[0041] The hydroelectric power generation unit condition evaluation method according to this embodiment analyzes the hydroelectric power generation unit's condition throughout its entire lifecycle, preventing situations of over-inspection or under-inspection, improving the accuracy of the condition analysis, or improving the accuracy of the condition evaluation results by determining the corresponding condition evaluation results based on the results of the entire lifecycle condition analysis. Therefore, by implementing this invention, the condition of the hydroelectric power generation unit can be evaluated effectively and reliably.

[0042] This embodiment provides a method for evaluating the condition of a hydroelectric power generation unit.

[0059] Step S2032: Based on each second dataset and each influencing element, analyze the state of the hydroelectric power unit under evaluation at each stage of its lifecycle to obtain the state analysis results for each stage of the hydroelectric power unit under evaluation.

[0060] Specifically, based on the second dataset for each lifecycle of the hydroelectric power unit under evaluation and each influencing factor that affects the state of the hydroelectric power unit under evaluation, the state of the hydroelectric power unit under evaluation at each lifecycle is analyzed, and the state analysis results for each lifecycle of the hydroelectric power unit under evaluation can be obtained.

[0061] By considering multiple influencing factors that affect the state of a hydroelectric power generation unit, the accuracy of the state analysis can be further improved.

[0062] Step S2033: Based on the state analysis results within each lifecycle, determine the overall lifecycle state analysis results for the hydroelectric power unit being evaluated.

[0063] Specifically, based on the state analysis results for each lifecycle of the hydroelectric power generation unit under evaluation, it is possible to obtain the state analysis results for the entire lifecycle of the hydroelectric power generation unit under evaluation, i.e., the total lifecycle state analysis results.

[0064] Step S204: Based on the results of the entire lifecycle state analysis, the state evaluation result of the hydroelectric power generation unit to be evaluated is determined. For details, please refer to step S103 in the embodiment shown in Figure 1, and a detailed explanation is omitted here.

[0065] The hydroelectric power generation unit condition evaluation method according to this embodiment analyzes the hydroelectric power generation unit's condition throughout its entire lifecycle, preventing situations of over-inspection or under-inspection. Furthermore, it considers multiple influencing factors that affect the condition of the hydroelectric power generation unit, thereby further improving the accuracy of the condition analysis. Alternatively, the accuracy of the condition evaluation results can be improved by determining the corresponding condition evaluation results based on the results of the entire lifecycle condition analysis.

[0066] This embodiment provides a method for evaluating the condition of a hydroelectric power generation unit. Figure 4 is a flowchart of the method for evaluating the condition of a hydroelectric power generation unit according to an embodiment of the present invention. As shown in Figure 4, the process includes the following steps S401 to S406.

[0067] Step S401: Obtain the first dataset for the entire lifecycle of the hydroelectric power generation unit under evaluation. For details, refer to step S101 in the embodiment shown in Figure 1, and a detailed explanation is omitted here.

[0068] Step S402: Based on the first dataset, a full-life cycle analysis is performed on the hydroelectric power generation unit under evaluation to obtain the full-life cycle state analysis results for the hydroelectric power generation unit under evaluation. For details, please refer to step S203 in the embodiment shown in Figure 2, and a detailed explanation is omitted here.

[0069] Step S403: Based on the results of the overall lifecycle state analysis, determine the state evaluation result for the hydroelectric power generation unit being evaluated.

[0070] Specifically, step S403 above includes steps S4031 and S4032 below.

[0071] Step S4031: Obtain a predetermined set of state evaluation conditions.

[0072] Here, the predetermined set of state evaluation conditions may include a first predetermined state evaluation condition, a second predetermined state evaluation condition, a third predetermined state evaluation condition, and a fourth predetermined state evaluation condition, each reflecting the evaluation conditions for different states of the hydroelectric power generation unit under evaluation.

[0073] Step S4032: Based on the results of the entire lifecycle state analysis, processing is performed according to a predetermined set of state evaluation conditions to obtain the state evaluation results for the hydroelectric power generation unit to be evaluated.

[0074] Here, the condition evaluation results of the hydroelectric power generation unit under evaluation are intended to reflect the current state of the hydroelectric power generation unit under evaluation, and may include normal state, potential hazard state, defective state, and failure state.

[0075] (1) A normal state means that the hydroelectric power generation unit is in a stable operating state.

[0076] (2) A potential hazardous condition means that the unit may be at any time during operation due to some design flaws in the hydroelectric power unit, some components being prone to damage, some parameter settings being unreasonable, or certain bugs in the logic of some programs in the unit control software.

[0077] (3) A defective condition means that a component or function of the hydroelectric power generation unit is damaged or malfunctioning, but the system will not shut down for a while and will only be able to maintain operation temporarily.

[0078] (4) A malfunction means that a critical component or function of the hydroelectric power unit is damaged or malfunctioning, which directly causes the unit to shut down and renders it inoperable.

[0079] Specifically, the state of the hydroelectric power generation unit being evaluated, corresponding to the results of the entire lifecycle state analysis, can be determined based on a predetermined set of state evaluation conditions.

[0080] In some selectable embodiments, step S4032 includes the following steps a1 to a5.

[0081] Step a1: Compare the results of the entire lifecycle state analysis with a predetermined set of state evaluation conditions.

[0082] Step a2 If the results of the overall lifecycle state analysis satisfy the first predetermined state evaluation condition, it is determined that the hydroelectric power generation unit under evaluation is in a normal state.

[0083] Step a3 If the results of the overall lifecycle state analysis satisfy the second predetermined state evaluation condition, it is determined that the hydroelectric power unit under evaluation is in a potentially dangerous state.

[0084] Step a4 If the results of the entire lifecycle state analysis satisfy the third predetermined state evaluation condition, it is determined that the hydroelectric power generation unit under evaluation is in a defective state.

[0085] Step a5 If the results of the entire lifecycle state analysis satisfy the fourth predetermined state evaluation condition, it is determined that the hydroelectric power generation unit under evaluation is in a faulty state.

[0086] Specifically, by combining the results of the entire lifecycle state analysis with the failure conditions described in step S4032 above, a correspondence between the results of the entire lifecycle state analysis and a predetermined set of state evaluation conditions can be obtained. (1) If there are no problems in the overall lifecycle state analysis results, it indicates that the hydroelectric power generation unit under evaluation is in a stable operating state, i.e., in a normal state. (2) If the results of the full lifecycle state analysis show that some of the designs of the hydroelectric power unit are not rational, some components are likely to be damaged, some parameter settings are not rational, and some programs in the unit control software have certain bugs, then the hydroelectric power unit under evaluation may be at risk of becoming defective or failing at any time during operation, that is, the hydroelectric power unit under evaluation is in a potentially dangerous state. (3) If the results of the overall life cycle state analysis indicate that a component or function of the hydroelectric power generation unit is damaged or malfunctioning, the hydroelectric power generation unit under evaluation will not shut down for a period of time, but will only be able to maintain an operating state temporarily, that is, the hydroelectric power generation unit under evaluation will be in a defective state. (4) If the results of the full life cycle condition analysis indicate that a critical component or function of the hydroelectric power unit is damaged or malfunctioning, it indicates that the hydroelectric power unit under evaluation has stopped and is inoperable, i.e., that the hydroelectric power unit under evaluation is in a faulty state.

[0087] In one selectable embodiment, as shown in Figure 3, a process is provided to perform a full-life cycle analysis of the state of the hydroelectric power unit under evaluation based on a first dataset containing data from the four aspects of design and manufacturing, assembly and adjustment, operation and maintenance, and inspection technology improvement, and related influencing factors, thereby obtaining a full-life cycle state analysis result corresponding to the hydroelectric power unit under evaluation.

[0088] Step S404 Based on the condition evaluation results, determine whether or not the hydroelectric power generation unit being evaluated needs to be repaired.

[0089] Specifically, the condition evaluation results can reflect the condition of the hydroelectric power generation unit being evaluated, and therefore, based on the obtained condition evaluation results, it is possible to determine whether or not the hydroelectric power generation unit being evaluated needs to be repaired.

[0090] For example, if the condition evaluation result indicates that the hydroelectric power unit being evaluated is in one of the following states: potentially dangerous, defective, or malfunctioning, it indicates that the hydroelectric power unit being evaluated needs to be repaired. Conversely, if the condition evaluation result indicates that the hydroelectric power unit being evaluated is in a normal state, it indicates that the hydroelectric power unit does not need to be repaired.

[0091] Step S405: If the hydroelectric power generation unit under evaluation requires repair, obtain a repair method based on the condition evaluation results.

[0092] Specifically, if a hydroelectric power generation unit under evaluation needs repair, it may be in one of the following conditions: a potential hazardous condition, a defective condition, or a failure condition. In this case, different repair methods will be used depending on the condition.

[0093] Step S406: Repair the hydroelectric power generation unit under evaluation using the repair method.
