Description

Technical Field

[0001] The present invention relates to the field of power grid control operation and monitoring system acceptance, and in particular to an automatic acceptance method for a single-interval wiring diagram screen of a monitoring system. Background Art

[0002] As society continues to develop and electricity demand continues to grow, the number of substations in the power grid is rapidly increasing to ensure adequate power supply. This growing number of substations, coupled with the renovation of existing substations, is placing increasing pressure on centralized control stations to inspect and accept monitoring systems. Especially during the peak spring and autumn inspection periods and the commissioning of new substations, monitors face a significant amount of inspection work. Improving inspection efficiency and quality in these situations is a pressing issue for the monitoring industry. While sophisticated automated inspection equipment is currently in use for telesignaling and telemetering signals, the inspection of monitoring system images still relies on manual inspection by monitors. During peak periods, the inspection workload is substantial, often requiring several hours of continuous inspection. This carries the risk of incorrect or missed inspections due to fatigue, hindering efficiency and compromising the progress of new substation commissioning and the renovation of existing substations. Therefore, a new solution is necessary to address these challenges. Summary of the Invention

[0003] Purpose of the invention: In order to improve the automatic acceptance function of the monitoring system, the present invention proposes an automatic acceptance method for the single-interval wiring diagram screen of the monitoring system.

[0004] The present invention provides an automatic acceptance method for a single-interval wiring diagram screen of a monitoring system as follows:

[0005] (1) Divide the single-interval image of the monitoring system into regions and construct a standard position matrix;

[0006] (2) After changing the status of the field equipment one by one, the measurement position matrix is ​​constructed based on the comparison between the single-interval wiring diagram screen of the monitoring system and the screen of the previous state;

[0007] (3) Based on the comparison between the measured position matrix and the standard position matrix, determine whether each device in the single interval screen of the monitoring system has passed the acceptance and generate an acceptance report.

[0008] Specifically, the step (1) includes the following steps:

[0009] (1.1) Monitoring system single bay wiring diagram screen area division:

[0010] Typical single bay wiring diagram of monitoring system is shown in the appendix. Figure 1As shown, a typical single-bay monitoring system wiring diagram includes a circuit breaker, knife switch, switch grounding knife, and line grounding knife. During the inspection of the single-bay monitoring system wiring diagram, the position changes of these devices must be verified to ensure that the changes in the on-site device positions are consistent with the monitoring system diagram. The center point of the circuit breaker, knife switch, switch grounding knife, and line grounding knife in the single-bay monitoring system wiring diagram represents the device.

[0011] Furthermore, a suitable area is captured in the single-bay wiring diagram screen of the monitoring system. Since the circuit breakers, knife switches, switch grounding knife switches, and line grounding knife switches contained in the typical single-bay wiring diagram of the monitoring system have clear relative positions, the area is divided into several sub-areas to ensure that there is at most one center point of the above-mentioned equipment in each sub-area. This ensures that the circuit breaker, knife switch, switch grounding knife switch, and line grounding knife switch have only one sub-area corresponding to it, and the coordinates of the boundary pixel points of each sub-area are recorded.

[0012] (1.2) Constructing the standard position matrix

[0013] The above steps divide the single-bay wiring diagram of the monitoring system into several sub-areas corresponding to circuit breakers, switches, switch grounding switches, and line grounding switches. These sub-areas are represented by a matrix containing only 0 / 1 variables, in which each element corresponds one-to-one to the above sub-areas. This matrix is ​​denoted as the standard position matrix L.

[0014] Based on the distribution of elements with a value of 1 in the standard position matrix L, the relative positions of circuit breakers, switches, switch grounding switches, and line grounding switches in the monitoring system's single-bay wiring diagram can be determined. Based on the relative position distribution of devices in the monitoring system's single-bay wiring diagram, determining the position of one device allows for rapid computer identification of the remaining devices.

[0015] Furthermore, the step (2) includes the following steps:

[0016] (2.1) Constructing the measurement position matrix

[0017] A matrix containing only 0 / 1 variables, with each element in the matrix corresponding to the sub-region described in step (1) is used to represent the real-time status of the equipment in the single-bay wiring screen of the monitoring system, which is recorded as the measurement position matrix L c , which has the same order and correspondence with the standard position matrix L.

[0018] At the beginning of the acceptance, all elements in the position measurement matrix are set to 0, and the measurement position matrix at this time is recorded as L c0 ,Right now:

[0019]

[0020] At the same time, the corresponding measurement position matrix after the status of the on-site equipment changes i times during the acceptance process is L ci .

[0021] (2.2) Measurement position matrix update

[0022] During the acceptance process, the on-site personnel change the operating status of the circuit breaker, knife switch, and grounding knife switch equipment in turn, and the master station automatically accepts them one by one. The details are as follows:

[0023] (2.2.1) When the acceptance begins, capture the single-bay wiring image of the monitoring system and record the matrix consisting of the grayscale values ​​of the captured image as matrix p0;

[0024] (2.2.2) After the on-site personnel change the position of the circuit breaker, they capture the grayscale value matrix of the single-bay wiring screen of the monitoring system again and record it as matrix p1; it is required that during this process, under normal circumstances, the status of only one device on site changes.

[0025] (2.2.3) Calculate the image difference matrix

[0026]

[0027] Here, |p0-p1| is defined as the absolute value operation, for example:

[0028] but

[0029] (2.2.4) Define column vector

[0030] Row vector H2=[h 21 h 22 h 23 …h 2m ]=[111…1]

[0031] Difference row matrix Difference column matrix

[0032] Among them, m is the picture difference matrix The number of rows in the matrix, n is the image difference matrix The number of columns in the matrix.

[0033] (2.2.5) Calculate the center point coordinates (x i ,y i ),

[0034] Define the threshold value e=10, the difference row matrix p x The maximum row coordinate x of the element greater than the threshold e max and the minimum row coordinate xmin ,but Difference column matrix p y The maximum column coordinate y of the element greater than the threshold e max and the minimum column coordinate y min ,but

[0035] (2.2.6) Define the range matrix T

[0036]

[0037] where t i1 is the minimum row coordinate of the monitoring screen of the master station where device i is located, t i2 is the maximum row coordinate of the monitoring screen of the master station where device i is located, t i3 is the minimum column coordinate of the master station monitoring screen where device i is located, t i4 is the maximum column coordinate of the monitoring screen of the master station where device i is located, 1≤i≤7.

[0038] Defining the change matrix

[0039] When t k1 ≤x i ≤t k2 , t k3 ≤y i ≤t k4 When z=k, l z =1, when z≠k, l z =0.1≤k,z≤7.

[0040] (2.2.7) The measurement position matrix is:

[0041]

[0042] Specifically, in step (2.2.7), to further improve the reliability of automatic acceptance, the operation matrix M is introduced into the measurement position matrix update formula. At this time, the measurement position matrix update formula is:

[0043]

[0044] Where m i The elements of the operation matrix M satisfy 1≤i≤7. When the device state is changed for the kth time, when i=k, m i =1, when i≠k, m i =0; 1≤k≤7;

[0045] In the formula It is the matrix multiplication algorithm, that is, the matrix corresponding elements are multiplied, requiring M, are matrices of the same order. (For example: but )

[0046] The automatic acceptance of the remaining devices in the single bay wiring diagram of the monitoring system has a similar process, so the present invention will not repeat it. After completing the automatic acceptance of all devices in the single bay one by one, the final measurement position matrix L is obtained. c .

[0047] Furthermore, the step (3) includes the following steps:

[0048] Judging the acceptance results

[0049] By comparing the corresponding element values ​​in the standard position matrix and the measured position matrix, it is determined whether each device screen has passed the acceptance inspection. At the same time, the eigenvalue matrix is ​​introduced to extract the eigenvalue criteria for whether different devices have passed the acceptance inspection. The judgment formula is:

[0050] J=f1(LL c )f2

[0051] Where J is the discriminant matrix, which contains the eigenvalue criteria for whether each device has passed the acceptance test; f1 and f2 are eigenvalue matrices, whose values ​​are determined by the device to be judged.

[0053]

[0054] Get the discriminant matrix J1=(j 11 ,j 12 ,j 13 ), if j 11 = 0, the conclusion is: "The circuit breaker position has passed the acceptance", if j 11 >0, then a judgment is formed: "The circuit breaker position has not passed the acceptance and requires manual acceptance", if j 11 <0 or j 11 >1, then the judgment is: "system error"; if j 12 = 0, the conclusion is: "The busbar side switch position has passed the acceptance", if j 12 >0, then a judgment is formed: "The busbar side switch position has not passed the acceptance and needs manual acceptance". If j 12 <0 or j 12 >2, then the judgment is: "System error"; if j 13 = 0, the conclusion is: "The position of the switch on the line side has passed the acceptance inspection", if j 13 >0, then a judgment is formed: "The switch position on the line side has not passed the acceptance and needs manual acceptance". If j 13 <0 or j13 >1, then the judgment is formed: "System error".

[0056]

[0057] Get the discriminant matrix J2=(j 21 ,j 22 ,j 23 ), if j 21 = 0, the conclusion is: "The grounding switch position on the line side has passed the acceptance inspection", if j 21 >0, then a judgment is formed: "The grounding switch position on the line side has not passed the acceptance and needs manual acceptance". If j 21 <0 or j 21 >1, then the judgment is: "system error"; if j 22 = 0, the conclusion is: "The grounding switch 2 position on the circuit breaker side has passed the acceptance", if j 22 >0, then a judgment is formed: "The position of the grounding switch 2 on the circuit breaker side has not passed the acceptance and requires manual acceptance". If j 22 <0 or j 22 >1, then the judgment is: "system error"; if j 23 = 0, the conclusion is: "The grounding switch 1 on the circuit breaker side has passed the acceptance", if j 23 >0, then a judgment is formed: "The position of the grounding switch 1 on the circuit breaker side has not passed the acceptance and requires manual acceptance". If j 23 <0 or j 23 >1, then the judgment is formed: "System error".

[0058] When all elements in the discriminant matrices J1 and J2 are 0, the conclusion is formed: "This interval passes the acceptance."

[0065] Refer to the attached Figure 1-3 The present invention provides an automatic acceptance method for a single-interval wiring diagram screen of a monitoring system as follows:

[0066] (4) Divide the single-interval image of the monitoring system into regions and construct a standard position matrix;

[0067] (5) After changing the status of the field equipment one by one, the measurement position matrix is ​​constructed based on the comparison between the single-interval wiring diagram screen of the monitoring system and the screen of the previous state;

[0068] (6) Based on the comparison between the measured position matrix and the standard position matrix, determine whether each device in the single interval screen of the monitoring system has passed the acceptance and form an acceptance report.

[0069] Specifically, the step (1) includes the following steps:

[0070] (1.1) Monitoring system single bay wiring diagram screen area division:

[0071] Typical single bay wiring diagram of monitoring system is shown in the appendix. Figure 1 As shown in the figure, a typical single-bay wiring diagram of a monitoring system includes a circuit breaker, a knife switch, a switch grounding knife, and a line grounding knife. When accepting the single-bay wiring diagram of the monitoring system, it is necessary to check and accept the position changes of the above equipment to ensure that the position changes of the on-site equipment are consistent with the monitoring system diagram. The center point of the circuit breaker, knife switch, switch grounding knife, and line grounding knife in the single-bay wiring diagram of the monitoring system represents the equipment, as shown in the appendix. Figure 2As shown. Further, in the single bay wiring diagram of the monitoring system, a suitable area is intercepted. Since the typical single bay wiring diagram of the monitoring system contains circuit breakers, switches, switch grounding switches, and line grounding switches with clear relative positions, the area is divided into several sub-areas, ensuring that there is at most one center point of the above equipment in each sub-area, as shown in the appendix. Figure 3 As shown, this makes the circuit breaker, knife, switch grounding knife, and line grounding knife have only one sub-region corresponding to it, and records the boundary pixel coordinates of each sub-region.

[0072] (1.2) Constructing the standard position matrix

[0073] The above steps divide the single-bay wiring diagram of the monitoring system into several sub-areas corresponding to circuit breakers, switches, switch grounding switches, and line grounding switches. These sub-areas are represented by a matrix containing only 0 / 1 variables, with each element in the matrix corresponding to the above sub-areas one by one. This matrix is ​​denoted as the standard position matrix L. Figure 3 As an example, a 3×6 matrix is ​​used to represent the sub-areas shown in the figure, and a 0 / 1 variable is used to represent whether the sub-area contains the device center point. That is, the matrix element value corresponding to the sub-area containing the device center point is 1, and the matrix element value corresponding to the sub-area not containing the device center point is 0. Figure 3 The standard position matrix L in is:

[0074]

[0075] Based on the distribution of elements with a value of 1 in the standard position matrix L, the relative positions of circuit breakers, switches, switch grounding switches, and line grounding switches in the monitoring system's single-bay wiring diagram can be determined. Based on the relative position distribution of devices in the monitoring system's single-bay wiring diagram, determining the position of one device allows for rapid computer identification of the remaining devices.

[0084] (2.2.1) When the acceptance begins, capture the single-bay wiring image of the monitoring system and record the matrix consisting of the grayscale values ​​of the captured image as matrix p0;

[0085] (2.2.2) After the on-site personnel change the position of the circuit breaker, they capture the grayscale value matrix of the single-bay wiring screen of the monitoring system again and record it as matrix p1; it is required that during this process, under normal circumstances, the status of only one device on site changes.

At the same time, the eigenvalue matrix is ​​introduced to extract the eigenvalue criteria for whether different devices have passed the acceptance inspection. The judgment formula is:

[0111] J=f1(LL c )f2

[0112] Where J is the discriminant matrix, which contains the eigenvalue criteria for whether each device has passed the acceptance test; f1 and f2 are eigenvalue matrices, whose values ​​are determined by the device to be judged.
