[0045] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.

[0046] In this embodiment, the execution subject of the generator insulation degradation determination method is a terminal device. It is understandable that the types of terminal devices include but are not limited to mobile phones, tablet computers, laptops, ultra-mobile personal computers (Ultra-Mobile Personal Computer, UMPC), netbooks, personal digital assistants (Personal Digital Assistant, PDA), etc., and the embodiment of the application does not impose any restrictions on the specific types of terminal devices.

[0047] First, see Figure 1 The generator insulation degradation determination method provided in the embodiment of the present application comprises the following steps:

[0048] In S100, detection data set information and current aging cycle information of the motor to be detected are obtained.

[0049] Specifically, the terminal device can first obtain the current aging cycle information of the motor to be detected, and at the same time use a preset plurality of sensors to obtain the detection data set information of the motor to be detected, wherein the motor to be detected is used to describe the generator to be detected in the pumped-storage unit; the current aging cycle information is used to describe the current aging stage of the motor to be detected; and the detection data set information is used to describe the data collected for the detection of the motor to be detected.

[0050] In S200, the state threshold set information of the motor to be detected is determined according to the current aging cycle information.

[0051] Specifically, after the terminal device obtains the detection data set information and the current aging cycle information, the terminal device can quickly determine the state threshold set information of the motor to be detected according to the current aging cycle information.

[0052] To improve the accuracy of detection, please refer to Figure 2 Before step S200, the method further includes the following steps:

[0053] In S201, initial threshold set information is obtained, and full life cycle information corresponding to a plurality of reference motors is obtained.

[0054] Specifically, the terminal device can obtain the initial threshold set information and the full life cycle information corresponding to multiple reference motors at the same time, wherein the initial threshold set information includes multiple different types of initial threshold information; the reference motor is used to describe other generators as reference objects; the full life cycle information includes multiple different types of historical detection data information and the corresponding aging stage information of each historical detection data information; the type of the historical detection data information corresponds to the type of the initial threshold information;

[0055] Exemplarily, when the historical detection data information is historical data about the temperature between winding turns, the type of the initial threshold information is also the initial threshold about the temperature between winding turns; when the historical detection data information is historical data about the resistance of the insulating material, the type of the initial threshold information is also the initial threshold about the resistance of the insulating material; when the historical detection data information is historical data about the humidity of the insulating material, the type of the initial threshold information is also the initial threshold about the humidity of the insulating material.

[0056] In S202, based on the aging stage information, a plurality of different types of historical detection data information are classified to generate a plurality of detection data set information of the same order.

[0057] Specifically, after the terminal device obtains the initial threshold set information and the full life cycle information, the terminal device can classify multiple different types of historical detection data information based on the aging stage information to which it belongs, and generate multiple same-order detection data set information, wherein the same-order detection data set information includes multiple historical detection data information of the same type:

[0058] For example, a certain detection data set information of the same order may include detection data on the winding turn-to-turn temperature within six consecutive hours.

[0059] In S203, for each piece of historical detection data information in each piece of detection data set information of the same order: compare the historical detection data information with the initial threshold information.

[0060] Specifically, after the terminal device generates multiple same-order detection data set information, the terminal device can perform the processing for each historical detection data information in each same-order detection data set information: compare the historical detection data information with the initial threshold information.

[0061] In S204, if the historical detection data information is greater than the initial threshold information, fault type information is generated.

[0062] Specifically, if the historical detection data information is greater than the initial threshold information, fault type information is generated, wherein the fault type information is used to describe the fault type corresponding to the generator of the pumped storage unit.

[0063] In S205 , the multiple different types of initial threshold information are sorted in order of the number of fault type information from large to small, and troubleshooting sequence information is generated.

[0064] Specifically, after the terminal device generates fault type information, the terminal device can sort multiple different types of initial threshold information in order from most to least amount of fault type information, and generate troubleshooting sequence information, wherein the troubleshooting sequence information is used to describe multiple different types of initial threshold information arranged in order from most to least.

[0065] In S300, comprehensive state evaluation information is generated according to the detection data set information and the state threshold set information.

[0066] Specifically, after the terminal device generates the troubleshooting sequence information, the terminal device can generate comprehensive status evaluation information based on the detection data set information and the state threshold set information, wherein the detection data set information includes multiple instantaneous detection information; the state threshold set information includes multiple state threshold information, and the comprehensive status evaluation information is severe degradation information, mild degradation information or state qualified information, wherein the severe degradation information is used to describe the insulation degradation condition of the motor to be detected as severe degradation; the mild degradation information is used to describe the insulation degradation condition of the motor to be detected as mild degradation; and the state qualified information is used to describe the insulation degradation condition of the motor to be detected as not degraded and can continue to be put into use.

[0067] To further improve the accuracy of the test, please refer to Figure 3 Before step S300, the method further includes the following steps:

[0068] In S301, target aging stage information is determined according to current aging cycle information.

[0069] Specifically, the terminal device can effectively determine the target aging stage information according to the current aging cycle information of the motor to be detected, wherein the target aging stage information is used to describe the same aging stage information as the current aging cycle information.

[0070] In S302, target sequence information is determined according to target aging stage information.

[0071] Specifically, after the terminal device determines the target aging stage information, the terminal device can effectively determine the target sequence information according to the target aging stage information, wherein the target sequence information is used to describe the troubleshooting sequence information associated with the target aging stage information.

[0072] In S303, the target sequence information is divided according to the preset division quantity information to generate core sub-sequence information and secondary sub-sequence information.

[0073] Specifically, after the terminal device determines the target sequence information, the terminal device can divide the target sequence information according to the preset division quantity information to generate core sub-sequence information and secondary sub-sequence information. Exemplarily, when the division quantity information is five, the terminal device can determine the first five initial threshold information in the target sequence information as the core sub-sequence information, and then determine the remaining initial threshold information as the secondary sub-sequence information.

[0074] To improve the real-time performance of detection and judgment, please refer to Figure 4 , step S300 includes the following steps:

[0075] In S310, at least one pair of instantaneous detection information and state threshold information of the same type is compared based on the core sub-sequence information.

[0076] Specifically, the terminal device may compare at least one pair of instantaneous detection information and state threshold information of the same type based on the core sub-sequence information.

[0077] In S320, if the instantaneous detection information is greater than the state threshold information, severe degradation information is generated, otherwise, based on the secondary sub-sequence information, at least one other pair of instantaneous detection information and state threshold information of the same type is compared.

[0078] Specifically, if the instantaneous detection information is greater than the state threshold information, the terminal device may generate severe degradation information, otherwise the terminal device may compare at least one other pair of instantaneous detection information and state threshold information of the same type based on the secondary sub-sequence information.

[0079] In S330, if the remaining at least one pair of instantaneous detection information of the same type is greater than the state threshold information, slight degradation information is generated; otherwise, state qualified information is generated.

[0080] Specifically, if the instantaneous detection information is greater than the status threshold information, the terminal device can generate mild degradation information, otherwise the terminal device can generate qualified status information, thereby realizing real-time detection of the generator of the pumped storage unit, and realizing detection of components that are more likely to deteriorate in a more reasonable order, ensuring that effective detection and maintenance resources can be used where they are most needed, thereby improving resource utilization.

[0081] For more targeted maintenance of pumped storage generators, please refer to Figure 5 After step S300, the method further includes the following steps:

[0082] In S400, if the comprehensive state evaluation information is severe degradation information, first maintenance plan information is generated according to the fault type information corresponding to the core sub-sequence information.

[0083] Specifically, if the comprehensive status assessment information is severe degradation information, the terminal device can generate first maintenance plan information based on the fault type information corresponding to the core sub-sequence information, wherein the first maintenance plan information is used to prompt the operation and maintenance personnel to repair each insulation degradation fault of the motor to be inspected according to the core sub-sequence information.

[0084] In S410, if the comprehensive state evaluation information is slight degradation information, the second maintenance plan information is generated according to the fault type information corresponding to the secondary sub-sequence information.

[0085] Specifically, if the comprehensive status assessment information is mild degradation information, the terminal device can generate second maintenance plan information based on the fault type information corresponding to the secondary sub-sequence information, wherein the second maintenance plan information is used to prompt the operation and maintenance personnel to repair each insulation degradation fault of the motor to be inspected according to the secondary sub-sequence information.

[0086] The implementation principle of the method for determining insulation degradation of a generator of a pumped-storage unit applicable to the embodiment of the present application is as follows: the terminal device can first obtain the detection data set information and the current aging cycle information of the motor to be detected in real time, and then quickly determine the state threshold set information of the motor to be detected based on the current aging cycle information, and finally effectively generate comprehensive state evaluation information based on the detection data set information and the state threshold set information, thereby realizing real-time judgment of the operating status of the generator of the pumped-storage unit, facilitating determination of the insulation performance and the health status of the entire equipment under the actual operating voltage, and effectively improving the real-time performance of the detection.
