Description

Technical Field

[0001] The present invention relates to the technical field of computer optimization strategies, and in particular to a method for optimizing the opening and closing time, and an analysis system, device, and storage medium. Background Art

[0002] The status monitoring of high-voltage circuit breakers is the premise and basis for realizing their fault diagnosis. Usually, sensors detect the electrical data of the circuit breaker's operating status, and then the control module analyzes the electrical data to adjust the control instructions for parameters such as the circuit breaker's opening and closing time and applied voltage to control the circuit breaker's reasonable operation.

[0003] There are two main existing methods for monitoring the status of circuit breakers. One of them is to use the vibration signal of the circuit breaker for analysis. This method uses a vibration sensor to collect the vibration signal when the circuit breaker is in action, and extracts information reflecting the status of the mechanical mechanism of the circuit breaker. The advantage of using vibration signals to diagnose circuit breaker faults is that it can reflect the overall health of the circuit breaker, but it is difficult to extract fault information, and the vibration signal is greatly affected by the sensor installation position and the circuit breaker structure. If the correspondence between the vibration signal characteristics and the fault type is to be established, a large amount of fault data is required, the number of training samples is large, and the fault data of circuit breakers with different structures are different, which makes the model construction more complicated.

[0004] Another way is to use the current signal of the coil during the opening and closing action of the circuit breaker for analysis. Although the current signal of the circuit breaker coil cannot reflect the overall status information of the circuit breaker, it is relatively easy to obtain the current signal, and the structure of the circuit breaker coil is not much different, and the current characteristics are basically the same. In addition, the circuit breaker coil is the starting mechanism for the opening and closing actions, and plays a key role in the opening and closing actions of the circuit breaker. Fault diagnosis of the opening and closing coils can effectively avoid the occurrence of false operation and refusal to operate faults of the circuit breaker. However, there is currently no reasonable calculation model to optimize the operation control of the circuit breaker based on the diagnostic data. Summary of the invention

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0033] like Figure 1 As shown, a method for optimizing the opening and closing time according to an embodiment of the first aspect of the present invention includes:

[0034] S110, controlling each circuit breaker to perform multiple opening and closing actions, obtaining control instructions in each opening and closing action, and collecting electrical data at different times in each opening and closing action;

[0035] S120, analyzing potential fault results according to electrical data, and fitting control instructions, electrical data, and fault results into characteristic data;

[0036] S130, performing iterative operations on the feature data for the random ethnic groups based on the black-winged kite algorithm model;

[0037] S140, adjusting the fitness value of the black kite algorithm model so that the black kite algorithm model reaches the number of iterations and converges;

[0038] S150, controlling the target circuit breaker to perform multiple opening and closing actions, and collecting electrical data in each opening and closing action of the target circuit breaker;

[0039] S160. Substituting the electrical data collected by the target circuit breaker into the adjusted Black Kite algorithm model, the adjusted Black Kite algorithm model optimizes the control instructions for the target circuit breaker, wherein the control instructions are used to control the opening and closing time of the target circuit breaker.

[0040] Among them, a current transformer can be set in the coil of the circuit breaker 200, and the current transformer is used to detect the current information of the circuit breaker 200 as electrical data. The opening and closing time of each circuit breaker 200 is controlled by the control module 300 in the electrical system. Specifically, the control module 300 may include a processor such as a CPU and its auxiliary circuits, and also includes a drive unit composed of a switch tube or a relay. The drive unit is connected to the coil of the circuit breaker 200. The processor outputs a control instruction to control the driving unit to close, so that the coil of the circuit breaker 200 is energized. The coil of the circuit breaker 200 is energized to drive the circuit breaker 200 to open and close.

[0041] During the circuit breaker opening and closing process, Figure 2 As shown, it includes the following stages:

[0042] Stage 1: t0~t1; t0 is the time when the circuit breaker opening and closing command is issued. The circuit breaker coil is energized at t0, and the current rises exponentially. t1 is the time when the closing coil core starts to move, and the current starts to drop. This stage can reflect the state of the circuit breaker coil.

[0043] Stage 2: t1-t2; at t1, due to the increase of the circuit breaker coil current, the iron core begins to accelerate under the action of the electromagnetic force, and the current begins to decrease. t2 indicates that the iron core touches the load of the operating machine, the moving contact starts to move, and the iron core stops moving. This stage reflects the movement state of the electromagnet core, whether there is jamming, tripping, or changes in the energy release mechanical load, etc.

[0044] Stage 3: t2-t3, the process in which the operating mechanism drives the contacts to close. When the iron core hits the closing lock device to lock the door or valve, the iron core stops moving or bounces briefly, and the current begins to increase, causing the opening spring to start opening.

[0045] Stage 4: t3~t4, this stage is the continuation of stage 3, the current keeps increasing slowly, the current reaches a near steady state, and the breaking process continues;

[0046] Stage 5: t4~t5, at t4, the auxiliary contact of the circuit breaker is cut off and the current decreases rapidly. At t5, the loop current decreases to zero. During this stage, the auxiliary switch is disconnected, an arc is generated and elongated at the auxiliary switch contact key, and the arc voltage will increase rapidly, forcing the coil current to decrease rapidly. The contacts are completely separated, and the equivalent resistance between the contacts increases rapidly until the arc is completely extinguished.

[0047] The invention discloses a method for optimizing the opening and closing time, collects electrical data in the opening and closing actions of each circuit breaker, fits the control instructions, electrical data and fault results obtained by analysis in each opening and closing action into characteristic data, uses the characteristic data to construct a Black Kite algorithm model, performs iterative calculations on the Black Kite algorithm model, adjusts the fitness value of the Black Kite algorithm model so that the Black Kite algorithm model reaches the number of iterations and finally converges, and when optimizing the control instructions of the target circuit breaker, uses the adjusted Black Kite algorithm model to analyze the electrical data generated by the opening and closing actions of the target circuit breaker, and optimizes the control instructions of the target circuit breaker. The design monitors the electrical data of the circuit breaker coil, reasonably optimizes the control instructions of the opening and closing actions of the circuit breaker, and improves the operation stability.

[0048] In some embodiments of the present invention, the electrical data includes one or more of the maximum current value of the circuit breaker coil in the closing action, the maximum current value of the circuit breaker coil in the opening action, the current change rate of the circuit breaker coil before and after closing, the current change rate of the circuit breaker coil before and after opening, the average current of the circuit breaker coil in the opening action, and the average current of the circuit breaker coil in the closing action.

[0049] In some embodiments of the present invention, the control instruction is used to control the electrical variable target acting on the circuit breaker coil, and the electrical variable target includes the voltage amplitude applied at both ends of the circuit breaker coil, the voltage pulse width applied at both ends of the circuit breaker coil, and the slope of the current rising edge of the circuit breaker coil; in the iterative operation of the feature data on the random ethnic group based on the Black Kite algorithm model, it includes: using the electrical variable target as the decision variable of the Black Kite algorithm model to form an individual position vector.

[0050] Specifically, the Black Winged Kite Algorithm model BKA (Black Winged Kite Algorithm) optimizes the parameters of LSSVM and finds the optimal solution by performing iterative operations on random ethnic groups.

[0051] In step S130, a matrix of the black kite algorithm model is first constructed as an initial population to create a set of random solutions. The following matrix can be used to represent the position of each black kite (BK):

[0052]

[0053] Among them, pop is used to represent the number of potential solutions, dim is used to represent the size of the given problem dimension, and BK i,j is the position of the j-th black-winged kite in the ith row to ensure that the position of each black-winged kite is evenly distributed.

[0054] From this we can get:

[0055] X i =BK lb +rand(BK ub -BK lb );

[0056] Where i is an integer between 1 and pop, BK kb is the lower limit of the i-th black kite in the j-th row, BK ub is the upper limit of the i-th black kite in the j-th row, and rand is a value randomly selected between [0, 1].

[0057] The individual with the best fitness value in the initial population of the Black Kite Algorithm model is selected as the leader X L , this position is considered to be the best position for black-winged kites. Taking the minimum value as an example, the initial leader X L The mathematical representation of is:

[0058] f best =min(f(X i ));

[0059] X L =X(find(f best =f(X i )));

[0060] Mathematical model for simulating the attack behavior of black kites in the black kite algorithm model:

[0061]

[0062] in, represents the position of the jth black-winged kite in the ith row at the tth iteration, represents the position of the jth black kite in the ith row at the t+1th iteration, r is a random number ranging from 0 to 1, p is a constant value of 0.9, T is the total number of iterations, and t is the number of iterations completed so far.

[0063] Among them, simulating the attack behavior of the black-winged kite can include different attack behaviors for global exploration and search.

[0064] Bird migration is usually led by a leader. Therefore, a hypothesis based on bird migration is proposed. If the fitness value of the current population is less than the fitness value of the random population, the leader will give up leadership and join the migrating population, indicating that it is not suitable to lead the population forward. On the contrary, if the fitness value of the current population is greater than the fitness value of the random population, it will guide the population until it reaches the destination. The following is a mathematical model of black-winged kite migration behavior:

[0065]

[0066] m = 2 × sin (r + π / 2);

[0067] in, represents the leader of the black kites in the jth dimension at the tth iteration so far, represents the position of the jth black-winged kite in the ith row at the tth iteration, represents the position of the jth black-winged kite in the ith row at the t+1th iteration, F i represents the current position in the jth dimension obtained by any black-winged kite in the tth iteration, F ri represents the fitness value of a random position in the jth dimension obtained from any black kite in t iterations, and C(0, 1) represents the Cauchy mutation.

[0068] The Cauchy mutation is defined as a one-dimensional Cauchy distribution with two parameters.

[0069] Probability density function of the one-dimensional Cauchy distribution:

[0070]

[0071] When δ=1,μ=0,the probability density function will become the standard form, that is:

[0072]

[0073] In some embodiments of the present invention, in adjusting the fitness value of the Black Kite algorithm model so that the Black Kite algorithm model reaches the number of iterations and converges, the fitness value is obtained by weighted calculation of control instructions for the circuit breaker coil and operating requirements.

[0074] The fitness value of the Black Kite algorithm model and whether it can reach the expected fitness value determine the quality of the optimization result of the Black Kite algorithm model, and the fitness value can be set by the control instructions and operating requirements of the circuit breaker coil. Among them, the control instructions can be used to derive requirements for the on and off time of the circuit breaker coil, the applied voltage, the power consumption current of the circuit breaker coil, etc., while the operating requirements are the requirements set by the user for the failure rate or operating stability of the circuit breaker.

[0075] In some embodiments of the present invention, the control instruction includes controlling the closing time t of the circuit breaker. h , control the opening time t of the circuit breaker f And the power consumption current I of the control circuit breaker coil w , the operating requirements include the failure rate f a ;

[0076] Fitness value = w1×t h +w2×t f +w3×I w+w4×f a ;

[0077] Among them, w1 is the weight coefficient of controlling the closing time of the circuit breaker, w2 is the weight coefficient of controlling the opening time of the circuit breaker, w3 is the weight coefficient of controlling the power consumption current of the circuit breaker coil, and w4 is the weight coefficient of the failure rate.

[0078] In some embodiments of the present invention, fitting the control instructions, electrical data and fault results into characteristic data includes:

[0079] The least squares support vector machine algorithm is used to fit the characteristic data of control instructions, electrical data and fault results.

[0080] The least squares formula is called curve fitting in mathematics, including the linear regression equation and the least squares method of the matrix. The linear least squares formula is a=y-bx.

[0081] Support vector machine is a kind of generalized linear classifier that performs binary classification on data in a supervised learning manner. Its decision boundary is the maximum margin hyperplane solved for the learning samples.

[0082] By using the least squares method and support vector machine algorithm, the optimization index adopts the square term, and the equality constraint replaces the inequality constraint of the support vector machine. The quadratic programming problem is transformed into a linear equation system for solution, which reduces the computational complexity and speeds up the solution.

[0083] In some embodiments of the present invention, after collecting the electrical data at different times in each opening and closing action, the method includes: comparing the collected electrical data with a preset electrical abnormality range, and eliminating electrical data that exceeds the electrical abnormality range.

[0084] It is understandable that the staff can set the electrical abnormality range to clean the acquired electrical data. Abnormal data beyond the electrical abnormality range obviously does not conform to the operating characteristics of the circuit breaker. Therefore, the electrical data is eliminated to prevent interference with the construction of the Black Kite algorithm model.

[0085] According to the analysis system of the second aspect of the present invention, Figure 3 As shown, it includes: a collection module 400, which is used to collect electrical data of each circuit breaker 200 and a target circuit breaker 200; a control module 300, which is connected to the collection module 400, and the control module 300 is used to execute the opening and closing time optimization processing method disclosed in any of the above embodiments to optimize the control instructions for the target circuit breaker 200.
