[0046] The following will describe in detail the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0047] It should be noted that all actions of obtaining signals, information or data in the present disclosure are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where it is located and obtaining the authorization given by the owner of the corresponding device.

[0048] As described in the background art, with the long - term operation of the generator set and factors such as the wear of the unit hardware, the actual operation laws of the high - lift valves of the unit in the sequence valve mode deviate from the design curve, thus affecting the regulation performance of the generator set, changing the linearity of the unit flow characteristic curve, and resulting in insensitive unit load regulation.

[0049] In view of this, the present disclosure provides a high - lift valve operating state monitoring method, device, unit and electronic device. By matching the data of the high - lift valve in actual operation with the design curve, the monitoring of the operating state of the high - lift valve is realized, and early warning is carried out when a unit flow characteristic deviation fault occurs.

[0050] Figure 1 It is a flowchart of a high - lift valve operating state monitoring method shown according to an embodiment of the present disclosure. Taking the application of this method to a thermal power generating unit as an example, the method includes the following steps:

[0051] In step S101, the gas distribution law operation curve corresponding to the unit is equally divided into a preset number of sub - intervals.

[0052] Among them, referring to Figure 2 , the gas distribution law operation curve refers to the opening sequence and opening law of each high - lift valve in the unit, and mainly represents the functional relationship between the comprehensive flow command of the unit and the opening of each high - lift valve.

[0053] Specifically, the slopes of the gas distribution law operation curves under different comprehensive flow commands are not the same. It is necessary to calculate the distance values between the operating parameters of each high - lift valve and the law operation curve respectively. By equally dividing the comprehensive flow command in the gas distribution law operation curve into multiple sub - intervals, the deviation states of the actual operation curves of each high - lift valve in the sub - intervals corresponding to the gas distribution law operation curve are judged respectively.

[0054] Illustrate by way of example, referring toFigure 2 , for each high-pressure regulating valve, the comprehensive flow command in the range of [0 - 100%] is divided into N sub-ranges, where N is not less than 100, and the splitting points are set as FDEM0, FDEM1, ···, FDEM N , and the opening commands of the high-pressure regulating valves corresponding to each splitting point are V0, V1, ···, V N , thus forming a set of points of the comprehensive flow command and the opening of the high-pressure regulating valve [(FDEM0, V0), (FDEM1, V1), ···, (FDEM N , V N )].

[0055] Among them, the set of points of the comprehensive flow command and the opening of the high-pressure regulating valve is not evenly distributed, but is distributed according to the starting order of the high-pressure regulating valves.

[0056] For example, see Figure 3 , when the high-pressure regulating valve is the first group of valves to open, the interval section corresponding to the opening of the high-pressure regulating valve being 0 does not exist, and the number of splitting points is not set, then only the number of splitting points in the interval section where the opening of the high-pressure regulating valve is 100% is guaranteed to be 0.1N; see Figure 4 , when the high-pressure regulating valve is the second group of valves to open, in the interval section where the opening of the high-pressure regulating valve is 0, the number of splitting points is 0.1N, in the interval section where the opening of the high-pressure regulating valve is 100%, the number of splitting points is 0.1N, and in the interval of the opening adjustment of the high-pressure regulating valve, the number of splitting points is 0.8N; see Figure 5 , when the high-pressure regulating valve is the last group of valves to open, the interval section corresponding to the opening of the high-pressure regulating valve being 100% does not exist, and the number of splitting points is not set, then only the number of splitting points in the interval section where the opening of the high-pressure regulating valve is 0 is guaranteed to be 0.1N.

[0057] In step S102, calculate the distance calculation values corresponding to each sub-range.

[0058] Specifically, calculate the distance values of each high-pressure regulating valve in each sub-range respectively to obtain the distance calculation values corresponding to each sub-range.

[0059] In step S103, compare the distance calculation values corresponding to each sub-range with their corresponding distance thresholds respectively.

[0060] Specifically, the distance thresholds are not exactly the same in different interval sections. In the interval where the opening of the high-pressure regulating valve is 0, it can be determined according to the deviation value between the high-pressure regulating valve command of the unit and the actually obtained opening command of the high-pressure regulating valve; in the interval where the opening of the high-pressure regulating valve is 100%, it can be determined according to the deviation value between the high-pressure regulating valve opening command of the unit and the actually obtained opening command of the high-pressure regulating valve. In this disclosure, the distance threshold is set to 1.5.

[0061] In step S104, give an early warning according to the comparison result.

[0062] Specifically, warning information is generated according to the comparison result and pushed to the maintenance personnel.

[0063] The present disclosure equally divides the gas distribution law operation curve into a preset number of sub-intervals, calculates the distance calculation values corresponding to each sub-interval, compares the distance calculation values with their corresponding distance thresholds, realizes the quantitative analysis of the deviation degree between the gas distribution law curve of the unit and the actual operation data, realizes the monitoring of the actual operation law of the high-pressure regulating valve, and gives a warning when the actual operation law of the high-pressure regulating valve deviates greatly, so that the maintenance personnel can process it in time and avoid the insensitivity of the unit load regulation caused by the deviation of the actual operation law of the high-pressure regulating valve.

[0064] To facilitate a better understanding of the high-pressure regulating valve operation state monitoring method proposed by the present disclosure by those skilled in the art, the above steps will be illustrated by examples below.

[0065] In a feasible embodiment, in step S102, calculating the distance calculation values corresponding to each sub-interval includes:

[0066] For each sub-interval, construct the flow characteristic curve corresponding to each high-pressure regulating valve in the sub-interval;

[0067] Obtain the operation parameters of each high-pressure regulating valve, and determine the distance value of the high-pressure regulating valve according to the operation parameters and the flow characteristic curve, where the operation parameters include the opening of the high-pressure regulating valve and the comprehensive flow command;

[0068] Obtain the distance calculation value corresponding to the sub-interval according to the multiple distance values corresponding to the sub-interval.

[0069] Illustratively, obtain the comprehensive flow command FDEM of the unit at time t t and the opening V of the jth high-pressure regulating valve j t , to obtain the time series composed of the comprehensive flow command and the opening of the high-pressure regulating valve: T = ···, (FDEM t-1 , VF j t-1 ), (FDEM t , VF j t ), (FDEM t+1 , VF j t+1 ), ···. According to the comprehensive flow command FDEM of the unit at time t t obtain the above time series T the comprehensive flow command intervals corresponding to the values at each moment in, so as to determine the flow characteristic curve corresponding to this interval: Calculate the value of the jth high-pressure regulating valve at time t (FDEM t , VF jt ) The distance from the flow characteristic curve corresponding to this interval.

[0070] In a feasible embodiment, in step S102, constructing the flow characteristic curve corresponding to each high-pressure regulating valve in the sub-interval includes:

[0071] For each high-pressure regulating valve, obtaining any two adjacent segmentation points of the high-pressure regulating valve within the sub-interval;

[0072] Obtaining the comprehensive flow command interval and the opening interval corresponding to the high-pressure regulating valve according to the two segmentation points;

[0073] Constructing the flow characteristic curve corresponding to the high-pressure regulating valve according to the comprehensive flow command interval and the opening interval.

[0074] For example, let the two adjacent segmentation points within the opening adjustment interval of the j-th high-pressure regulating valve be (FDEM j i , V j i ), (FDEM j i+1 , V j i+1 ), then the comprehensive flow command interval corresponding to the j-th high-pressure regulating valve is R j i = [FDEM j i , FDEM j i+1 , and the opening interval of the high-pressure regulating valve is [V j i , V j i+1 . Thus, the flow characteristic curve corresponding to the j-th high-pressure regulating valve is obtained:

[0075]

[0076] Among them, (FDEM) represents the flow characteristic curve corresponding to the i-th comprehensive flow command interval [V j i , V j i+1 of the j-th high-pressure regulating valve of the unit; FDEM represents the comprehensive flow value within the i-th comprehensive flow command interval [V j i , V j i+1 .

[0077] In a feasible embodiment, in step S102, determining the distance value of the high-pressure regulating valve according to the operating parameters and the flow characteristic curve includes:

[0078] Obtain the slope and intercept of the flow characteristic curve;

[0079] Calculate the distance value corresponding to the high - lift valve according to the slope, intercept, high - lift valve opening, and comprehensive flow command.

[0080] For example, to obtain the slope and intercept of the flow characteristic curve:

[0081] k j i =(V j i- V j i+1 ) / (FDEM j i -FDEM j i+1 ),

[0082] b j i =[(V j i- V j i+1 ) / (FDEM j i -FDEM j i+1 )]·FDEM j i+1 ,

[0083] Substitute the values of the j - th high - lift valve at time t (FDEM t , VF j t ) and the slope k j i and intercept b j i of the flow characteristic curve corresponding to this interval into the following calculation formula to obtain the distance between the high - lift valve at time t and its corresponding flow characteristic curve:

[0084]

[0085] In a feasible embodiment, in step S102, obtaining the distance calculation value corresponding to the sub - interval according to the multiple distance values corresponding to the sub - interval includes: summing and averaging each distance value to obtain the distance calculation value corresponding to the sub - interval.

[0086] For example, for the entire time series T =···, (FDEM t-1 , VF j t-1 ), (FDEM t , VF j t ), (FDEMt+1 , VF j t+1 ), ··· Sum the distance values between all the points belonging to the j-th high-pressure regulating valve in the i-th interval and [···], and take the average value to obtain the flow characteristic curve corresponding to the j-th high-pressure regulating valve, and calculate the corresponding distance calculation value:

[0087]

[0088] In a feasible embodiment, in step S104, an early warning is made according to the comparison result, including:

[0089] When there is a distance calculation value corresponding to any interval greater than the distance threshold, an offset early warning information is generated for early warning.

[0090] In the present disclosure, calculating the deviation between the value corresponding to any high-pressure regulating valve at the current moment and the flow characteristic curve corresponding to this interval, and performing segmented statistics and averaging on the deviation results can fully eliminate the problem that due to the overly large distribution of the valve timing operation curve, the real-time data calculation results are scattered around the valve timing operation curve, resulting in an abnormally large deviation from the calculation result, and improve the reliability and accuracy of the comparison result.

[0091] Illustratively, taking a certain six high-pressure regulating valve unit as an example, see Figure 6 , each curve is the valve timing curve of each high-pressure regulating valve in the unit, and the scatter data is the actual operation data of the unit. Based on the valve distribution law curve of each high-pressure regulating valve, the valve distribution law curve of each high-pressure regulating valve is equally divided into 100 sub-intervals, and the corresponding high-pressure regulating valve opening interval and the slope and intercept of its valve distribution law curve are solved. Taking the high-pressure regulating valve GV4 as an example, the results are shown in Table 1 below:

[0092] Comprehensive flow command Gv4 opening Slope Intercept [0，1] [0，0] 0 0 [1，2] [0，0] 0 0 [2，3] [0，0] 0 0 ··· ··· ··· ··· [77，78] [89.8，95.05] 2.62 -197.21 [78，79] [95.05，100] 2.523911 -189.42 [79，80] [100，100] 2.353077 -175.93 [80，81] [100，100] 0.901202 -59.78 [81，82] [100，100] 0.901202 -59.78 [82，83] [100，100] 0.901218 -59.78 [83，84] [100，100] 1.657029 -122.51 [84，85] [100，100] 1.657029 -122.51 [85，86] [100，100] 1.657029 -122.49 [86，87] [100，100] 1.656233 -122.44 ··· ··· ··· ···

[0093] Table 1

[0094] Calculate the distance data in each interval section according to the data in Table 1, and compare each distance data with 1.5 to obtain the comparison result, as Figure 7 shown. It can be seen that the deviation values do not exceed 1.5. Therefore, the actual operating state of the high-pressure regulating valve GV4 matches well with its corresponding valve timing operation curve, and no early warning is required.
