[0060] Figure 3 is a schematic structural diagram of a control device for fault switching of a hydro-generator governor provided by an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0061] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0062] To solve this problem, an embodiment of the present invention provides a control method for fault switching of a hydro-generator governor. Figure 1 is a schematic flowchart of a control method for fault switching of a hydro-generator governor provided by an embodiment of the present invention. As Figure 1 shown, the method includes the following steps:

[0063] Step 101: Obtain the operation data of the hydro-generating unit and determine the target type of the operation data.

[0064] In the embodiment of the present invention, the operation data of the hydro-generating unit can be obtained through sensors.

[0065] Moreover, in the embodiment of the present invention, after obtaining the operation data of the hydro-generating unit, the target type of the operation data can be determined according to the numerical range or numerical unit of the operation data.

[0066] Among them, in the embodiment of the present invention, the target type of the above operation data may include opening degree, power, and frequency.

[0067] Moreover, in the embodiment of the present invention, each type of operation data corresponding to the target type corresponds to at least one signal, so that after one of the signals fails, the hydro-generating unit can be fault-diagnosed through other signals. Specifically, in the embodiment of the present invention, the operation data may include a first signal, a second signal, and a third signal.

[0068] Step 102: Based on the target type of the operation data, determine the target mode of the operation data corresponding to the governor.

[0069] In the embodiment of the present invention, different types of operation data have different data importance. Based on this, different types of operation data correspond to different target modes of the governor.

[0070] Specifically, in the embodiment of the present invention, if the target type of the operation data is the opening degree, it is determined that the target mode of the operation data corresponding to the governor is the first mode; if the target type of the operation data is the power, it is determined that the target mode of the operation data corresponding to the governor is the second mode; if the target type of the operation data is the frequency, it is determined that the target mode of the operation data corresponding to the governor is the third mode.

[0071] Among them, in the embodiment of the present invention, each type of operation data corresponding to the target type may correspond to two sets of the same governors to avoid the situation of a single governor failure. Moreover, in the embodiment of the present invention, for each sensor corresponding to the operation data, the signal can be split into two by a distributor and respectively transmitted to different governors, so that the data in the two governors is the same. Figure 2 This is a schematic connection diagram of the operation data and the governor proposed in the embodiment of the present invention. As Figure 2 shown, Sensor 1 obtains the same first signal a through Distributor 1 and inputs it into Governor Set A and Governor Set B respectively; Sensor 2 obtains the same second signal b through Distributor 2 and inputs it into Governor Set A and Governor Set B respectively; Sensor 3 obtains the same third signal c through Distributor 3 and inputs it into Governor Set A and Governor Set B respectively.

[0072] Step 103, perform a first fault determination on the operation data to obtain a first fault result.

[0073] In the embodiment of the present invention, the method for performing a first fault determination on the operation data to obtain a first fault result includes the following steps:

[0074] Step 1031, respectively perform a first fault determination on the first signal, the second signal, and the third signal in the operation data based on the fault determination rules corresponding to the target type of the operation data, to obtain the fault feedback results of the first signal, the second signal, and the third signal, where the fault feedback result includes feedback fault or no feedback fault;

[0075] Step 1032, determine the fault feedback results of the first signal, the second signal, and the third signal as the first fault result.

[0076] Among them, in the embodiment of the present invention, the fault determination rules corresponding to different types of operation data are also different.

[0077] Specifically, in the embodiment of the present invention, when the above operation data is opening and power, the corresponding fault determination rules are the same. Table 1 shows a kind of fault determination rules corresponding to the operation data of opening and power proposed in the embodiment of the present invention.

[0078] Table 1

[0079]

[0080] As shown in Table 1, the fault classifications corresponding to the opening and power can include loss of positioning parameters, disconnection fault, dead value fault, jump fault, overlimit fault, and deviation fault, and each fault type has corresponding threshold definition, threshold range, and threshold setting value.

[0081] And, in the embodiment of the present invention, Table 2 shows a kind of fault determination rules corresponding to the operation data of frequency proposed in the embodiment of the present invention.

[0082] Table 2

[0083]

[0084] As shown in Table 2, the fault classifications corresponding to the frequency can include disconnection fault, jump fault, and deviation fault, and each fault type has corresponding threshold definition, threshold range, and threshold setting value.

[0085] Furthermore, in the embodiment of the present invention, respectively perform a determination on the first signal, the second signal, and the third signal in the operation data through the fault determination rules to obtain the fault feedback results of the first signal, the second signal, and the third signal, and determine the fault feedback results of the first signal, the second signal, and the third signal as the first fault result.

[0086] Step 104: Based on the first fault result and the target mode, perform a second fault judgment on the operation data, and control the fault switching of the hydro-generator governor based on the obtained second fault result.

[0087] In the embodiment of the present invention, after obtaining the first fault result and the target mode of the operation data through the above steps, a second fault judgment can be performed on the operation data based on the first fault result and the target mode, and the fault switching of the hydro-generator governor can be controlled based on the obtained second fault result.

[0088] Among them, in the embodiment of the present invention, the method of performing a second fault judgment on the operation data based on the first fault result and the target mode, and controlling the fault switching of the hydro-generator governor based on the obtained second fault result may include the following steps:

[0089] Step 1041: If there is no feedback fault in the first fault result, calculate the difference between any two of the first signal, the second signal, and the third signal to obtain the corresponding difference result.

[0090] Step 1042: Based on the difference result and the target mode, perform a second fault judgment on the operation data, and control the fault switching of the hydro-generator governor based on the obtained second fault result.

[0091] Step 1043: If there is a feedback fault in the first fault result, control the fault switching of the hydro-generator governor based on the target mode and the first signal, the second signal, and the third signal.

[0092] In the embodiment of the present invention, if there is no feedback fault in the first fault result, it indicates that the first signal, the second signal, and the third signal are all normal. At this time, it is necessary to calculate the difference between any two of the first signal, the second signal, and the third signal to obtain the corresponding difference result, so as to perform a second fault judgment on the operation data according to the difference result, and control the fault switching of the hydro-generator governor based on the obtained second fault result.

[0093] Among them, in the embodiment of the present invention, the difference result corresponding to the first signal and the second signal is the first difference; the difference result corresponding to the second signal and the third signal is the second difference; the difference result corresponding to the first signal and the third signal is the third difference.

[0094] Further, in the embodiments of the present invention, the method for performing a second fault determination on the operation data based on the difference result to obtain a second fault result may include: if the first difference is greater than the deviation threshold, the third difference is greater than the deviation threshold, and the second difference is less than the deviation threshold - 50, and the duration threshold, then the second fault result is that there is a deviation fault in the first signal; if the first difference is greater than the deviation threshold, the second difference is greater than the deviation threshold, and the third difference is less than the deviation threshold - 50, and the duration threshold, then the second fault result is that there is a deviation fault in the second signal; if the third difference is greater than the deviation threshold, the second difference is greater than the deviation threshold, and the first difference is less than the deviation threshold - 50, and the duration threshold, then the second fault result is that there is a deviation fault in the third signal; if the third difference is greater than the deviation threshold, the second difference is greater than the deviation threshold, and the first threshold is greater than the deviation threshold, and the duration threshold, then the second fault result is that there are deviation faults in all signals; otherwise, the second fault result is that there is no deviation fault. Among them, the deviation threshold and the time threshold can be set according to customer needs. By way of example, the time threshold is 500 ms.

[0095] Further, in the embodiments of the present invention, the method for controlling the fault switching of the hydro-generator governor based on the obtained second fault result may include: if the second fault result is that there are deviation faults in all signals, then output a total fault and perform a switching operation on the governor; if the second fault result is that there is a deviation fault, then perform a fault reset on the corresponding signal; if the second fault result is that there is no deviation fault, then do nothing.

[0096] Further, in the embodiments of the present invention, the above method for controlling the fault switching of the hydro-generator governor based on the first fault result having a feedback fault and based on the target mode and the first signal, the second signal, and the third signal may include: if the target mode is the first mode, then determine the fault feedback result of the first signal; if the fault feedback result of the first signal is no feedback fault, then determine the first signal as the target signal; if the fault feedback result of the first signal is a feedback fault, then determine the fault feedback result of the second signal; if the fault feedback result of the second signal is no feedback fault, then determine the second signal as the target signal, and output a total fault and perform a switching operation on the governor; if the fault feedback result of the second signal is a feedback fault, then determine the third signal as the target signal, and output a total fault and perform a switching operation on the governor; if the fault feedback result of the third signal is a feedback fault, then determine the target signal as a preset value and output a total fault. Among them, the above preset value can be set according to needs. By way of example, the preset value is 0.

[0097] Moreover, in the embodiments of the present invention, the method for controlling the fault switching of the hydro-generator governor based on the target mode and the first signal, the second signal, and the third signal when there is a feedback fault in the first fault result may include: if the target mode is the second mode, determining the fault feedback result of the first signal; if the fault feedback result of the first signal is a feedback fault, determining whether the fault feedback results of the second signal and the third signal meet the first condition; if the fault feedback results of the second signal and the third signal meet the first condition, determining the second signal as the target signal, outputting a total fault, and performing a switching operation on the governor; if the fault feedback result of the second signal is a feedback fault, determining whether the fault feedback results of the first signal and the third signal meet the second condition; if the fault feedback results of the first signal and the third signal meet the second condition, determining the first signal as the target signal, outputting a total fault, and performing a switching operation on the governor; if the fault feedback result of the third signal is a feedback fault, determining whether the fault feedback results of the first signal and the second signal meet the third condition; if the fault feedback results of the first signal and the second signal meet the third condition, determining the first signal as the target signal, outputting a total fault, and performing a switching operation on the governor; otherwise, outputting a total fault and performing a switching operation on the governor.

[0098] Wherein, in the embodiments of the present invention, the first condition is that the fault feedback result of the second signal is no feedback fault, the fault feedback result of the third signal is no feedback fault, and the second difference is less than the deviation threshold; the second condition is that the fault feedback result of the first signal is no feedback fault, the fault feedback result of the third signal is no feedback fault, and the third difference is less than the deviation threshold; the third condition is that the fault feedback result of the first signal is no feedback result, the fault feedback result of the second signal is no feedback result, and the first difference is less than the deviation threshold.

[0099] Furthermore, in the embodiments of the present invention, the method for controlling the fault switching of the hydro-generator governor based on the target mode and the first signal, the second signal, and the third signal when there is a feedback fault in the first fault result may include: if the target mode is the third mode, determining the fault feedback result of the first signal; if the fault feedback result of the first signal is no feedback fault, determining the first signal as the target signal; if the fault feedback result of the first signal is a feedback fault, determining the fault feedback result of the second signal; if the fault feedback result of the second signal is no feedback fault, determining the second signal as the target signal; if the fault feedback result of the second signal is a feedback fault, determining the third signal as the target signal; if the fault feedback result of the third signal is a feedback fault, determining the target signal as a preset value, outputting a total fault, and performing a switching operation on the governor.
