[0023] In order to clarify the objectives, technical solutions and advantages of the embodiments of the present application, the technical solutions of the embodiments of the present application will be described below clearly and completely with reference to the drawings of the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Any other embodiments that can be obtained by those skilled in the art based on the embodiments of the present application without any creative efforts fall within the scope of protection of the present application.

[0024] As the core power generating equipment of a hydroelectric power station, hydroelectric power generating units require regular inspection and maintenance work to ensure normal operation. Currently, inspections of hydroelectric power generating units in China are often carried out through periodic inspections in accordance with inspection technical standards, and periodic inspections are divided into Class A, Class B, Class C, and Class D inspections.

[0025] Class A inspection refers to an inspection method in which the hydroelectric generator is completely disassembled to inspect and repair the equipment in order to maintain, restore or improve its performance.

[0026] A Class B inspection involves partial disassembly of the hydroelectric generating equipment to inspect and repair it.

[0027] A Class C inspection is when equipment wear and deterioration is regular and the equipment is inspected, evaluated, repaired, and cleaned intensively.

[0028] A Class D inspection is an inspection in which the overall equipment is in good operating condition and repairs are carried out to eliminate defects in the main equipment and its associated systems.

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

[0030] Due to the inconsistency in factors such as the equipment production manufacturing quality and operation and maintenance level of the hydroelectric power generation units of each power plant, regular inspections will result in the units being over-inspected or under-inspected. In order to solve this problem, each power plant has been studying the content of condition inspections one after another. The determination of inspection items for the condition of the hydroelectric generators is generally based on the evaluation of the condition of the hydroelectric power generation unit. However, the current condition evaluation is generally based on the unit's condition monitoring system and some factors, so the condition evaluation results are not good.

[0031] Therefore, the embodiment of the present application provides a condition assessment method for a hydroelectric power unit, and achieves the effect of effectively and accurately assessing the condition of a hydroelectric power unit through a whole life cycle analysis of the condition of the hydroelectric power unit.

[0032] According to an embodiment of the present application, an embodiment of a method for assessing the condition of a hydroelectric power unit is provided, and it is noted that the steps shown in the flowcharts of the drawings may be performed, for example, in a computer system as a set of computer-executable instructions, and that although the flowcharts show a logical order, in some cases the steps shown or described may be performed in an order different from that shown here.

[0033] In this embodiment, a method for assessing the condition of a hydroelectric power unit is provided. FIG. 1 is a flowchart of the method for assessing the condition of a hydroelectric power unit according to the embodiment of the present application. As shown in FIG. 1, the process includes the following steps S101 to S103:

[0034] Step S101: A first data set is acquired for the entire life cycle of the hydroelectric power generation unit to be evaluated.

[0035] Here, the complete life cycle may include all processes from design, model selection, manufacturing, assembly, adjustment, testing, operation, maintenance, inspection, technical upgrade, and disposal of the hydroelectric power unit.

[0036] The first data set represents equipment-related data for the entire life cycle of the hydroelectric power unit under evaluation.

[0037] Step S102: Based on the first data set, perform a full life cycle analysis of the state of the hydroelectric power unit to be evaluated to obtain a full life cycle state analysis result of the hydroelectric power unit to be evaluated.

[0038] Specifically, the first dataset can reflect the equipment status throughout the entire life cycle of the hydroelectric power unit being evaluated, and therefore, based on the first dataset, the status of the hydroelectric power unit being evaluated can be analyzed throughout its life cycle to obtain corresponding entire life cycle status analysis results.

[0039] Step S103: Based on the result of the whole life cycle condition analysis, the condition evaluation result of the hydroelectric power generating unit to be evaluated is determined.

[0040] Specifically, the results of the full life cycle condition analysis can reflect the condition of the hydroelectric power unit being evaluated throughout its entire life cycle, and therefore, the current condition of the hydroelectric power unit being evaluated can be further evaluated based on the results of the full life cycle condition analysis obtained through the analysis.

[0041] The condition assessment method for a hydroelectric power unit according to the present embodiment analyzes the condition of the hydroelectric power unit over its entire life cycle, preventing over-inspection or under-inspection, improving the accuracy of the condition analysis, or determining the corresponding condition assessment result based on the result of the entire life cycle condition analysis, thereby improving the accuracy of the condition assessment result. Therefore, by implementing the present invention, the condition of a hydroelectric power unit can be assessed effectively and accurately.

[0059] Step S2032: Analyze the state of the hydroelectric power unit to be evaluated in each life cycle based on each second data set and each influencing factor to obtain a state analysis result of the hydroelectric power unit to be evaluated in each life cycle.

[0060] Specifically, the condition of the hydroelectric power generation unit to be evaluated during each life cycle can be analyzed based on the second dataset during each life cycle of the hydroelectric power generation unit to be evaluated and each influencing factor that affects the condition of the hydroelectric power generation unit to be evaluated, and condition analysis results for each life cycle of the hydroelectric power generation unit to be evaluated can be obtained.

[0061] The accuracy of the condition analysis is further improved by considering multiple influencing factors that affect the condition of the hydroelectric power unit.

[0062] Step S2033: Based on the condition analysis results within each life cycle, the overall life cycle condition analysis results of the hydroelectric power generating unit to be evaluated are determined.

[0063] Specifically, based on the condition analysis results for each life cycle of the hydroelectric power generation unit being evaluated, the condition analysis results for the entire life cycle of the hydroelectric power generation unit being evaluated, i.e., the entire life cycle condition analysis results, can be obtained.

[0064] Step S204: Determine the condition assessment result of the hydroelectric power unit to be assessed based on the result of the whole life cycle condition analysis. For details, refer to step S103 in the embodiment shown in Figure 1, and detailed description will be omitted here.

[0065] The condition assessment method for a hydroelectric power unit according to this embodiment analyzes the condition of the hydroelectric power unit over its entire life cycle, avoiding over-inspection or under-inspection, and further improving the accuracy of the condition analysis by considering multiple influencing factors that affect the condition of the hydroelectric power unit, or by determining the corresponding condition assessment result based on the result of the entire life cycle condition analysis, thereby improving the accuracy of the condition assessment result.

[0066] In this embodiment, a method for assessing the condition of a hydroelectric power unit is provided. FIG. 4 is a flowchart of the method for assessing the condition of a hydroelectric power unit according to the embodiment of the present application. As shown in FIG. 4, the process includes the following steps S401 to S406:

[0067] Step S401: Obtain a first data set for the entire life cycle of the hydroelectric power unit to be evaluated. For details, refer to step S101 in the embodiment shown in Figure 1, and detailed description thereof will be omitted here.

[0068] Step S402: Based on the first data set, perform a full life cycle analysis of the status of the hydroelectric power unit to be evaluated to obtain a full life cycle status analysis result of the hydroelectric power unit to be evaluated. For details, refer to step S203 in the embodiment shown in Figure 2, and detailed description will be omitted here.

[0069] Step S403: Based on the result of the whole life cycle condition analysis, the condition evaluation result of the hydroelectric power generating unit to be evaluated is determined.

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

[0071] In step S4031, a predetermined state evaluation condition set is acquired.

[0072] Here, the set of predetermined condition evaluation conditions may include a first predetermined condition evaluation condition, a second predetermined condition evaluation condition, a third predetermined condition evaluation condition, and a fourth predetermined condition evaluation condition, each of which is intended to reflect evaluation conditions in different states of the hydroelectric power generation unit being evaluated.

[0073] Step S4032: Based on the results of the overall life cycle condition analysis, processing is performed using a predetermined set of condition evaluation conditions to obtain a condition evaluation result for the hydroelectric power generating unit to be evaluated.

[0074] Here, the condition assessment result of the hydroelectric power unit being evaluated is intended to reflect the current condition of the hydroelectric power unit being evaluated, and may include a normal condition, a potentially dangerous condition, a fault condition, and a failure condition.

[0075] (1) Normal condition means that the hydroelectric power generating unit is in a stable operating condition.

[0076] (2) A potentially dangerous state refers to the fact that some designs of the hydroelectric power unit are not reasonable, some components are likely to be damaged, some parameter settings are not reasonable, and there are certain bugs in the logic of some programs in the unit's control software, which may cause the unit to enter a defective or failed state at any time during operation.

[0077] (3) A fault condition means that a component or function of a hydroelectric power unit is damaged or in an abnormal operating state for a period of time, but does not result in the system being shut down, and the system is barely able to temporarily maintain an operating state.

[0078] (4) A fault condition means that a critical component or function of a hydroelectric power unit is damaged or abnormal, causing the unit to shut down directly and become inoperable.

[0079] Specifically, the condition of the hydroelectric power unit being evaluated can be determined based on a predetermined set of condition assessment criteria, which corresponds to the results of the overall life cycle condition analysis.

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

[0081] Step a1: Compare the results of the overall life cycle condition analysis with a set of predetermined condition evaluation criteria.

[0082] Step a2: If the result of the whole life cycle condition analysis satisfies a first predetermined condition evaluation condition, it is determined that the hydroelectric power generation unit to be evaluated is in a normal state.

[0083] Step a3: If the result of the whole life cycle condition analysis satisfies a second predetermined condition evaluation condition, it is determined that the hydroelectric power unit being evaluated is in a potentially dangerous state.

[0084] Step a4: If the result of the whole life cycle condition analysis satisfies a third predetermined condition evaluation condition, it is determined that the hydroelectric power unit being evaluated is in a defective state.

[0085] Step a5: If the result of the whole life cycle condition analysis satisfies a fourth predetermined condition evaluation condition, it is determined that the hydroelectric power generation unit being evaluated is in a fault state.

[0086] Specifically, the results of the overall life cycle condition analysis can be combined with the failure conditions described in step S4032 above to obtain a correspondence between the results of the overall life cycle condition analysis and a predetermined set of condition evaluation conditions; (1) If the results of the full life cycle condition analysis show no problems, it indicates that the hydroelectric power unit being evaluated is in a stable operating condition, i.e., in a normal state; (2) If the results of the full life cycle condition analysis show that some designs of the hydroelectric power unit are not reasonable, some components are likely to be damaged, some parameter settings are not reasonable, and some program logic of the unit control software has certain bugs, it indicates that the hydroelectric power unit being evaluated may enter a defective state or a faulty state at any time during operation, that is, the hydroelectric power unit being evaluated is in a potentially dangerous state; (3) If the results of the full life cycle condition analysis show that a component or function of the hydroelectric power unit is damaged or in an abnormal operating state, the hydroelectric power unit being evaluated will temporarily maintain an operational state without causing a system outage for a period of time, i.e., the hydroelectric power unit being evaluated is in a defective state; (4) If the results of the full life cycle condition analysis indicate that a significant component or function of the hydroelectric power unit is damaged or abnormal, the evaluated hydroelectric power unit will be shut down and inoperable, i.e., the evaluated hydroelectric power unit will be in a failed state.

[0087] In one alternative embodiment, as shown in FIG. 3, a process is provided in which the state of the hydroelectric power unit being evaluated is analyzed throughout its life cycle based on a first dataset including data on the four aspects of design and manufacturing, assembly and adjustment, operation and maintenance, and inspection technology improvement and related influencing factors, to obtain a whole life cycle state analysis result corresponding to the hydroelectric power unit being evaluated.

[0088] In step S404, it is determined whether the hydroelectric power generating unit to be evaluated needs repair based on the condition evaluation result.

[0089] Specifically, the condition assessment results can reflect the condition of the hydroelectric power generation unit being evaluated, and therefore, based on the obtained condition assessment results, it can be determined whether the hydroelectric power generation unit being evaluated needs to be repaired.

[0090] For example, if the condition assessment result indicates that the hydroelectric power generation unit being evaluated is in one of a potentially dangerous state, a defective state, and a failed state, it indicates that the hydroelectric power generation unit being evaluated needs to be repaired; conversely, if the condition assessment result indicates that the hydroelectric power generation unit being evaluated is in a normal state, it indicates that the hydroelectric power generation unit being evaluated does not need to be repaired.

[0091] Step S405: If the hydroelectric power generating unit to be evaluated needs to be repaired, a repair method is obtained based on the condition evaluation result.

[0092] Specifically, when the hydroelectric power unit being evaluated needs to be repaired, the hydroelectric power unit being evaluated may be in one of a potential dangerous state, a defective state, and a fault state, and at this time, different repair methods are obtained according to different states.

[0093] In step S406, the hydroelectric power generating unit to be evaluated is repaired using the repair method.

[0094] Specifically, based on the acquired repair method, repair operations for the hydroelectric power generation unit being evaluated can be completed, further improving the reliability of the hydroelectric power generation unit.

[0095] The condition assessment method for a hydroelectric power unit according to this embodiment can quickly and accurately obtain a condition assessment result for a hydroelectric power unit by comparing the results of the entire life cycle condition analysis with a predetermined set of condition assessment criteria, thereby shortening the assessment time and improving the accuracy of the condition assessment result. Alternatively, the condition assessment result can be used to quickly and effectively identify whether a hydroelectric power unit needs repair, allowing hydroelectric power units that need repair to be repaired immediately, fundamentally solving equipment failures and significantly improving the reliability of the hydroelectric power unit.

[0096] This embodiment further provides a state assessment device for a hydroelectric power generation unit, which is used to implement the above-described embodiments and alternative embodiments, and detailed descriptions of those already described will be omitted. As used below, the term "module" refers to a combination of software and / or hardware capable of implementing a predetermined function. While the device described in the following embodiment is preferably implemented by software, it is also possible and envisioned to implement it by hardware or a combination of software and hardware.

[0097] This embodiment provides a state assessment device for a hydroelectric power unit, which includes an acquisition module 501, an analysis module 502 and a determination module 503, as shown in FIG.

[0098] The acquisition module 501 is for acquiring a first data set for the entire life cycle of the hydroelectric power unit under evaluation.
