Description

Technical Field

[0001] The present invention relates to a calculation method for the total light annunciator of main and auxiliary equipment in a centralized control station based on multi-dimensional modeling, and belongs to the technical field of substation monitoring. Background Art

[0002] With the development of the substation integrated automation system, the amount of information monitored by the centralized control center is becoming increasingly large. It is necessary to effectively and intuitively monitor various types of information. In particular, a large number of alarm signals and their accompanying signals are generated in the accident state, which puts forward higher requirements for the maintenance personnel to quickly locate the cause of the accident and make correct handling.

[0003] As an important means of operation and maintenance monitoring, the light annunciator configures important monitoring signals as light annunciator signal points and summarizes them layer by layer according to the OR logic. The operation and maintenance personnel only need to monitor a small number of interfaces. When an alarm or accident occurs, they can search down layer by layer to quickly locate the cause of the accident.

[0004] At present, there are many studies on the summary calculation of light annunciators, but most of these studies are for substation automation. For the new light annunciator calculation requirements generated by the rapid growth of the scale of centralized control stations and the more complex equipment hierarchical relationships, the existing studies fail to cover them well. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a calculation method for the total light annunciator of main and auxiliary equipment in a centralized control station based on multi-dimensional modeling. By analyzing the internal connection between light signal points and establishing statistical models in multiple dimensions, the calculation efficiency and accuracy can be greatly improved.

[0006] To achieve the above object, the present invention provides a calculation method for the total light annunciator of main and auxiliary equipment in a centralized control station based on multi-dimensional modeling, including:

[0007] Obtain the remote signal, accident and alarm light annunciator signal points, and establish a data structure model of the signal points;

[0008] Perform summary calculation on the light signals and output the results.

[0009] Further, if the status and quantity of the light annunciator signal points participating in the calculation change, perform summary calculation on the light signals in the changed light annunciator signal points and output the results.

[0010] Further, establishing a data structure model of the light annunciator signal points includes:

[0011] Obtain the information of the equipment associated with the light annunciator signal, and obtain all the signal points of the same equipment type as the light annunciator signal points;

[0012] Obtain the parent equipment objects at all levels of the light annunciator signal points.

[0013] Further, obtain all signal points of the same device type as the light signal point, including:

[0014] If the device type is the main device, obtain all signal points with the same interval as the light signal point and all signal points of the same device type as the light signal point;

[0015] If the device is an auxiliary device, obtain all auxiliary device signal points in the same substation as the light signal point and all signal points of the same device type as the light signal point.

[0016] Further, if the device type is the main device, obtain all signal points with the same interval as the light signal point and all signal points of the same device type as the light signal point, including:

[0017] If the device is a primary device, obtain all signal points of the same device type as the light signal point;

[0018] Otherwise, obtain all signal points in the same switch cabinet as the light signal point and all signal points of the same device type as the light signal point.

[0019] Further, perform a summary calculation on the light signals and output the results, including:

[0020] Obtain the status change data of the light signal point;

[0021] If the light signal point acts, the virtual remote signal output points corresponding to the parent objects at all levels of the light signal point act, and the virtual remote signal output points of the parent objects of the same type as the light signal point act;

[0022] If the light signal is restored:

[0023] If the other signal points at the same level are restored, the output points of the upper-level parent object are restored and the calculation is passed upward, and the output points of the upper-level parent object of the same type as the light signal point are restored and the calculation is passed upward.

[0024] Further, the signal points with the same interval as the light signal point include the remote signal points of primary devices, the remote signal points of secondary devices, the accident points of secondary devices, and the alarm points of secondary devices under the interval.

[0025] Further, the change in the status of the light signal point includes signal action or restoration, unconfirmed or confirmed;

[0026] The change in the number of light signal points includes whether the signal point participates in the light calculation after the device is tagged or untagged, and the addition or deletion of light signal points.

[0027] Further, the signal points of the same device type as the light signal point include:

[0028] Signal points with the same equipment type as the light signal board are selected from the point sequences obtained from all signal points at the same interval as the light signal board, all signal points in the same cubicle as the light signal board, and all auxiliary equipment signal points in the same substation as the light signal board.

[0029] Furthermore, obtaining all signal points at the same interval as the light signal board, obtaining all signal points in the same cubicle as the light signal board, and obtaining all auxiliary equipment signal points in the same substation as the light signal board are used to model the relationship in the longitudinal dimension;

[0030] Obtaining all signal points with the same equipment type as the light signal board is used to model the relationship in the horizontal dimension.

Detailed Embodiment

[0037] The present invention will be further described below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention.

[0038] An embodiment of the present invention provides a calculation method for the total annunciator of main and auxiliary equipment in a centralized control station based on multi-dimensional modeling, which specifically obtains the signal points of remote signals, accidents, and annunciator light signs to construct a structural model of data points, and summarizes and calculates the annunciator light sign signals. Compared with the prior art, it can meet more application scenarios; at the same time, the present invention adopts a multi-dimensional modeling method to specifically obtain the signal points of remote signals, accidents, and annunciator light signs. The constructed model is simple and clear, can effectively reduce the amount of calculation, and improve the calculation efficiency and accuracy.

[0039] As Figures 1 to 4 shown, the calculation method for the total annunciator of main and auxiliary equipment in a centralized control station based on multi-dimensional modeling provided by the embodiment of the present invention includes the following steps:

[0040] As Figure 1 shown:

[0041] Step S1: Screen out the signal points of remote signals, accidents, annunciators, etc. participating in the calculation.

[0042] Step S2: Establish a multi-dimensional data structure of the signal points.

[0043] Step S3: Summarize and calculate the light word signals and output the results.

[0044] Step S4: Monitor the status changes of the points participating in the calculation. If the status and quantity change, then transfer to Step S3; otherwise, continue with Step S4.

[0045] In specific implementation, as Figure 2 shown, Step S2 specifically includes:

[0046] Step S2.1: Obtain the equipment associated with the annunciator light sign signal. If the equipment type is the main equipment, then transfer to Step S2.2; if it is the auxiliary equipment, then transfer to Step S2.4.

[0047] Step S2.2: Obtain all the signal points in the same interval as the annunciator light sign signal point. If the annunciator light sign signal point corresponds to secondary equipment, then transfer to Step S2.3; if the corresponding equipment is primary equipment, then transfer to Step S2.5.

[0048] Step S2.3: Obtain all the signal points in the same switch cabinet as the annunciator light sign signal point, and transfer to Step S2.5 after completion.

[0049] Step S2.4: Obtain all the signal points of the auxiliary equipment in the same substation as the annunciator light sign signal point, and transfer to Step S2.5 after completion.

[0050] Step S2.5: Obtain all the signal points of the same equipment type as the annunciator light sign signal point.

[0051] Step S2.6: Obtain the parent objects at all levels of the annunciator light sign signal point.

[0052] In step S2.2 of the embodiment of the present invention: The signal points at the same interval as the light signal points include the primary equipment remote signal points and secondary equipment remote signal points, secondary equipment accident points, and secondary equipment alarm points under the interval.

[0053] In step S2.5 of the embodiment of the present invention: All signal points of the same equipment type as the light signal points refer to the signal points with the same equipment type as the light signal points screened out from the point sequences obtained in steps S2.2, S2.3, and S2.4.

[0054] As Figure 4 shown in the X direction in this figure, in this embodiment, steps S2.2, S2.3, and S2.4 are modeling relationships in the longitudinal dimension. Specifically, the longitudinal relationship between primary equipment and secondary equipment is: bay level -> substation level -> operation and maintenance team level -> central control station level, and the longitudinal relationship of auxiliary equipment is: substation level -> operation and maintenance team level -> central control station level. For secondary equipment, there is also a model relationship in the physical location dimension such as panel cabinet -> substation room -> floor.

[0055] As Figure 4 shown in the Y direction in this figure, in this embodiment, step S2.5 is a model relationship in the horizontal dimension of equipment type.

[0056] In this embodiment, for step S2.6, the parent objects at all levels of the light signal points refer to: for primary and secondary equipment: bay, substation, operation and maintenance team, central control station; for secondary equipment, there are also panel cabinet, substation room, floor; for auxiliary equipment: substation, operation and maintenance team, central control station.

[0057] In specific implementation, as Figure 3 shown, step S3 specifically includes:

[0058] Step S3.1, if the light signal acts, then turn to step S3.2; if the light signal is reset, then judge whether the remaining signal points at the same level are in the reset state. If they are in the reset state, then turn to step S3.4, otherwise turn to step S3.2.

[0059] Step S3.2, the virtual remote signal output points corresponding to the parent objects at all levels of the light signal point act, and after execution, transfer to step S3.3.

[0060] Step S3.3, the virtual remote signal output points of the parent objects at all levels of the same type as the light signal point act, and after execution, the process ends.

[0061] Step S3.4, the output points of the upper-level parent object are reset and the calculation is transmitted upward. After execution, transfer to step S3.5.

[0062] Step S3.5: The output points of the upper-level parent object of the same type as the light-signal points are restored and the calculation is passed upward. After the execution is completed, the process ends.

[0063] In steps S3.2 - S3.5 of the embodiments of the present invention, the virtual tele-signal output points of each level of parent object refer to the tele-signal points established for the output of the light-word summary result. The summary scope of this tele-signal point can be objects such as intervals, substations, operation and maintenance classes, centralized control stations, switch cabinets, and small rooms. For the light-word statistics of the same equipment type, the device type associated with this virtual tele-signal point is the same as the device type corresponding to the light-word signal.

[0064] As Figure 4 Shown in the Z direction in, in this embodiment, in step S3 and its sub-steps, the content of the light-word summary calculation includes calculations in both the longitudinal dimension and the transverse dimension. At the same time, accident light-signal boards and warning light-signal boards are distinguished according to the alarm status link, and the device types cover primary equipment, secondary equipment, and auxiliary equipment.

[0065] In specific implementation, in step S4, the change in the light-signal board status refers to the signal "action" or "restoration", "unconfirmed" or "confirmed"; the change in the number of light-signal boards refers to whether the signal point participates in the light-word calculation after the device "hangs a sign" or "removes a sign", and the "new addition" or "deletion" of light-signal board signals.
