Abstract
Description
Technical Field
[0001] This invention relates to the field of computer optimization strategy technology, and in particular to a method, analysis system, device, and storage medium for optimizing gate opening and closing times. Background Technology
[0002] Condition monitoring of high-voltage circuit breakers is the prerequisite and foundation for fault diagnosis. Typically, sensors detect electrical data of the circuit breaker's operating status, and the control module analyzes the electrical data to adjust control commands for parameters such as the circuit breaker's opening and closing time and applied voltage, so as to control the circuit breaker to operate properly.
[0003] There are two main existing methods for monitoring the condition of circuit breakers. One method involves analyzing the vibration signals of the circuit breaker. This method uses vibration sensors to collect vibration signals when the circuit breaker operates, extracting information reflecting the state of the circuit breaker's mechanical structure. The advantage of using vibration signals to diagnose circuit breaker faults is that it can reflect the overall health of the circuit breaker. However, fault information extraction is difficult, and vibration signals are greatly affected by the sensor's installation location and the circuit breaker's structure. Establishing a correspondence between vibration signal characteristics and fault types requires a large amount of fault data, resulting in a large number of training samples. Furthermore, fault data differs for circuit breakers with different structures, making model construction quite complex.
[0004] Another approach is to analyze the current signal from the circuit breaker coil during its opening and closing operations. Although the current signal from the circuit breaker coil cannot reflect the overall state information of the circuit breaker, it is relatively easy to obtain, and the structures of circuit breaker coils are not significantly different, with essentially the same current characteristics. Furthermore, the circuit breaker coil is the initiating mechanism for opening and closing operations, playing a crucial role in these processes. Fault diagnosis of the opening and closing coils can effectively prevent circuit breaker maloperation and failure to operate. However, currently, there is no reasonable computational model to optimize the circuit breaker's operational control based on diagnostic data. Summary of the Invention

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

The terms "first," "second," etc., in the specification, claims, and the aforementioned 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 commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.
[0033] like Figure 1 As shown, a method for optimizing the opening and closing time according to a first aspect embodiment of the present invention includes:
[0034] S110: Control each circuit breaker to perform multiple opening and closing actions, acquire control commands for each opening and closing action, and collect electrical data at different times during each opening and closing action.
[0035] S120. Based on the analysis of potential fault results from electrical data, feature data is fitted from control commands, electrical data, and fault results.
[0036] S130. Iteratively calculate the feature data on a random racial group based on the Black-winged Kite algorithm model;
[0037] S140. Adjust the fitness value of the Black-winged Kite algorithm model so that the Black-winged Kite algorithm model reaches the required number of iterations and converges.
[0038] S150: Control the target circuit breaker to perform multiple opening and closing actions, and collect electrical data during each opening and closing action of the target circuit breaker.
[0039] S160. Substitute the electrical data collected by the target circuit breaker into the adjusted Blackwing Kite algorithm model. The adjusted Blackwing 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] A current transformer can be installed in the coil of the circuit breaker 200 to detect the current information of the circuit breaker 200 as electrical data. In the electrical system, the opening and closing time of each circuit breaker 200 is controlled by the control module 300. Specifically, the control module 300 may include a processor such as a CPU and its auxiliary circuits, as well as a drive unit composed of a switching transistor or a relay. The drive unit is connected to the coil of the circuit breaker 200. The processor outputs control commands to control the drive unit to close, energizing the coil of the circuit breaker 200. The energized coil of the circuit breaker 200 drives the circuit breaker 200 to open and close.
[0041] Among them, during the opening and closing process of the circuit breaker, such as 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 increases exponentially. t1 is the time when the closing coil core begins to move and the current begins to decrease. This stage can reflect the state of the circuit breaker coil.
[0043] Phase 2: t1~t2; At time t1, due to the increase of the circuit breaker coil current, the iron core begins to accelerate under the action of electromagnetic force, and the current begins to decrease. t2 indicates that the iron core touches the load of the operating mechanism, the moving contact begins to move, and the iron core stops moving. This phase reflects the movement state of the electromagnet core, whether there is jamming, tripping, energy release, mechanical load changes, etc.
[0044] Stage 3: t2~t3, the process of the operating mechanism driving the contacts to close the circuit breaker. When the iron core hits the closing locking device to lock the door or valve, the iron core stops moving or has a brief bounce, the current begins to increase, causing the opening spring to open the circuit breaker.
[0045] Stage 4: t3~t4, this stage is a continuation of stage 3. The current continues to increase slowly until it reaches an approximate steady state, and the switching process continues.
[0046] Stage 5: t4~t5. At time t4, the circuit breaker auxiliary contacts are cut off, and the current decreases rapidly. At time t5, the circuit current decreases to zero. During this stage, the auxiliary switch is disconnected, and an arc is generated and stretched in the auxiliary switch contact key. The arc voltage will rise 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] This invention provides a method for optimizing the opening and closing time of circuit breakers. It collects electrical data from the opening and closing actions of each circuit breaker, fits the control commands, electrical data, and fault results from each action to form feature data, and uses this feature data to construct a Black-Winged Kite algorithm model. The Black-Winged Kite algorithm model undergoes iterative computation, and its fitness value is adjusted to ensure it reaches the required number of iterations and eventually converges. When optimizing the control commands of the target circuit breaker, the adjusted Black-Winged Kite algorithm model is used to analyze the electrical data generated by the opening and closing actions of the target circuit breaker and optimize the control commands accordingly. This design monitors the electrical data of the circuit breaker coils and rationally optimizes the control commands for the opening and closing actions of the circuit breaker, thereby improving operational stability.
[0048] In some embodiments of the present invention, the electrical data includes one or more of the following: the maximum current value of the circuit breaker coil during closing operation, the maximum current value of the circuit breaker coil during opening operation, the rate of change of current of the circuit breaker coil before and after closing, the rate of change of current of the circuit breaker coil before and after opening, the average current of the circuit breaker coil during opening operation, and the average current of the circuit breaker coil during closing operation.
[0049] In some embodiments of the present invention, the control command is used to control electrical variable targets acting on the circuit breaker coil, the electrical variable targets including the voltage amplitude applied across the circuit breaker coil, the voltage pulse width applied across the circuit breaker coil, and the slope of the current rising edge of the circuit breaker coil; the iterative calculation of the feature data on the random population based on the Black-winged Kite algorithm model includes: using the electrical variable targets as decision variables of the Black-winged Kite algorithm model to form an individual position vector.
[0050] Specifically, the Black Winged Kite Algorithm (BKA) optimizes the parameters of the LSSVM by iteratively calculating random populations to find the optimal solution.
[0051] In step S130, the matrix of the Black-winged Kite algorithm model is first constructed as the initial population, and a set of random solutions is created. The following matrix can be used to represent the position of each Black-winged Kite (BK):
[0052]
[0053] Where pop represents the number of potential solutions, dim represents the dimension of the given problem, and BK represents the value of the solution. i,j It is the position of the j-th black-winged kite in the i-th row, to ensure that the position of each black-winged kite is evenly distributed.
[0054] Therefore, we can conclude that:
[0055] X i =BK lb +rand(BK ub -BK lb );
[0056] Where i is an integer between 1 and pop, BK kb Let BK be the lower bound value of the i-th black-winged kite in the j-th row. ub is the upper limit value of the i-th black-winged kite in the j-th row, and rand is a value randomly selected between [0, 1].
[0057] The individual with the best fitness in the initial population, selected by the Black-winged Kite algorithm model, is chosen as the leader, X. L This position is considered the optimal position for the Black-winged Kite. 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] A mathematical model simulating the attack behavior of black-winged kites in the black-winged kite algorithm model:
[0061]
[0062] in, This represents the position of the j-th black-winged kite in the i-th row during the t-th iteration. The position of the j-th black-winged kite in the i-th row during the (t+1)-th iteration is represented by r, which is a random number 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] The simulation of Blackwing Kite attack behavior can include different attack behaviors targeting global exploration and search.
[0064] Bird migration is typically led by a leader. Therefore, a hypothesis based on bird migration is proposed: if the fitness value of the current population is lower than that of a random population, the leader will relinquish leadership and join the migrating population, indicating that it is unsuitable to lead the group. Conversely, if the fitness value of the current population is higher than that of a random population, the leader will guide the group until it reaches its destination. The following is a mathematical model of the migratory behavior of the black-winged kite:
[0065]
[0066] m = 2 × sin(r + π / 2);
[0067] in, This indicates the leader of the black-winged kite in the j-th dimension during the t-th iteration so far. This represents the position of the j-th black-winged kite in the i-th row during the t-th iteration. F represents the position of the j-th black-winged kite in the i-th row during the (t+1)-th iteration. i F represents the current position in the j-th dimension obtained by any black-winged kite in t iterations. ri Let C(0, 1) represent the fitness value of a random position in the j-th dimension obtained from any black-winged kite in t iterations, and let C(0, 1) represent a Cauchy mutation.
[0068] The Cauchy mutation is defined as a continuous probability distribution with two parameters in a one-dimensional Cauchy distribution.
[0069] The probability density function of a one-dimensional Cauchy distribution:
[0070]
[0071] When δ = 1 and μ = 0, the probability density function will become in its standard form, i.e.:
[0072]
[0073] In some embodiments of the present invention, in adjusting the fitness value of the Blackwing Kite algorithm model so that the Blackwing Kite algorithm model reaches the required number of iterations and converges, the fitness value is calculated by weighting the control commands to the circuit breaker coil and the operating requirements.
[0074] The fitness value of the Blackwing Kite algorithm model and whether it can reach the expected fitness value determine the quality of the optimization results of the Blackwing Kite algorithm model. The fitness value can be set by the control commands and operating requirements of the circuit breaker coil. The control commands can be used to obtain requirements such as the circuit breaker coil's on / off time, applied voltage, and power consumption current. The operating requirements are the user's requirements for the circuit breaker's failure rate or operational stability.
[0075] In some embodiments of the present invention, the control command 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 operational requirements include a failure rate f a ;
[0076] Fitness value = w1 × t h +w2×t f +w3×I w+w4×f a ;
[0077] Where w1 is the weighting coefficient for controlling the closing time of the circuit breaker, w2 is the weighting coefficient for controlling the opening time of the circuit breaker, w3 is the weighting coefficient for controlling the power consumption current of the circuit breaker coil, and w4 is the weighting coefficient for the failure rate.
[0078] In some embodiments of the present invention, fitting control commands, electrical data, and fault results into feature data includes:
[0079] The least squares support vector machine algorithm is used to fit feature data to control commands, electrical data, and fault results.
[0080] The least squares formula is mathematically known as curve fitting, which includes linear regression equations and matrix least squares. The formula for linear least squares is a = y - bx.
[0081] Support Vector Machines (SVMs) are a type of generalized linear classifier that performs binary classification of data using supervised learning. Their decision boundary is the hyperplane with the maximum margin calculated from 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 system of linear equations to be solved, which reduces the computational complexity and speeds up the solution.
[0083] In some embodiments of the present invention, after collecting electrical data at different times during each opening and closing operation, the method includes: comparing the collected electrical data with a preset electrical anomaly range, and removing electrical data that exceeds the electrical anomaly range.
[0084] Understandably, staff can set an electrical anomaly range to clean the acquired electrical data. Abnormal data that exceeds the electrical anomaly range is clearly inconsistent with the operating characteristics of the circuit breaker, so such electrical data is discarded to prevent interference with the construction of the Blackwing Kite algorithm model.
[0085] An analysis system according to a second aspect embodiment of the present invention, such as Figure 3 As shown, it includes: a data acquisition module 400, used to acquire electrical data of each circuit breaker 200 and the target circuit breaker 200; and a control module 300, connected to the data acquisition module 400, the control module 300 being used to execute the opening and closing time optimization processing method disclosed in any of the above embodiments to optimize the control commands for the target circuit breaker 200.
