Fig. 1 shows a flow chart of a substation protection fixed value monitoring method according to the first embodiment of the present application, for convenience of explanation, only the portions relevant to the present embodiment are shown, and the details are as follows:
s102, obtaining a protection fixed value of the transformer substation protection device.
In a specific inspection process or in an adjustment stage, the protection fixed value of the protection device may need to be set for multiple times, the protection fixed value is used for ensuring that the substation equipment does not exceed the allowable range for working, and the set protection action starts the corresponding numerical parameter, and the protection fixed value is not allowed to change after being set under the general condition because the protection fixed value relates to the safe operation of the substation; the device parameters are operation data of main equipment of the transformer substation, an operation range is generally set, and when the parameters exceed the preset operation range, the equipment may be in operation with problems. There is therefore a need for a fast positioning of substation equipment where the protection values or device parameters change.
S104, generating a constant value list according to the protection constant value.
And generating a constant value list by the protection constant value according to a preset format.
S106, generating the check code corresponding to the fixed value list through a check code generation algorithm.
The check codes are calculated according to a CRC algorithm or a national cipher SM3 algorithm by reading protection fixed values in the fixed value sheets, and only one check code can be generated by one fixed value sheet, so that a plurality of groups of protection fixed values of each protection device correspond to one fixed value sheet, and each fixed value sheet has a unique corresponding check code.
S108, comparing the consistency of the check code and the reference check code, and obtaining a comparison result.
It should be noted that, the reference check code may be generated by a check code generation algorithm through a preset fixed value list, when the check code is consistent with the reference check code, it is indicated that the protection fixed value of the protection device is not changed, and when the check code is inconsistent with the reference check code, it is considered that the protection fixed value of the protection device is changed. Therefore, a plurality of devices with modified protection fixed values in all the protection devices can be rapidly distinguished, and the changed fixed values can be known only by automatically comparing the obtained protection fixed values with the protection fixed value data in the fixed value list corresponding to the reference check code aiming at the devices with modified fixed values.
Under the condition that one fixed value list corresponds to the check code with the protection fixed value and the check code with the device parameter, the corresponding reference check code is also divided into the reference check code with the protection fixed value and the reference check code with the device parameter, the check code with the protection fixed value and the reference check code with the protection fixed value are respectively compared in the comparison process, the check code with the device parameter and the reference check code with the protection fixed value are compared, and when any check code is inconsistent in comparison, the protection fixed value of the protection device is changed.
And S110, displaying the comparison result in a visual mode.
In one or more embodiments, the device parameters of the protection device may also generate a corresponding check code for the device parameter list by generating a corresponding device parameter list. By checking the check code of the device parameter list, whether the device parameters in the device parameter list change or not can be quickly positioned, and meanwhile, the device parameters of the protection devices positioned to change can be quickly read.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.
In one or more embodiments of the present application, a flow of a method for generating a reference check code is shown in fig. 2:
s202, acquiring a reference protection fixed value of the transformer substation protection device.
The reference protection fixed value is a preset fixed value, and when the transformer substation protection device is configured in an initialized manner, the protection fixed value of the protection device is the reference protection fixed value. In one or more embodiments, the calculated first reference constant value list of the protection device may be directly input, and the corresponding reference protection constant value may be obtained by analyzing the first reference constant value list.
S204, generating a reference constant value list according to the reference protection constant value.
In one or more embodiments, if the directly entered first benchmark score list conforms to a preset format, the previous step and the present step may be adjusted to directly proceed to the next step. However, in the actual implementation process, the format of the first reference value list may be changed according to the preference edited by the user, so that the first reference value list needs to be parsed first to obtain the reference protection value parameters therein, and then a second reference value list with a preset format is generated according to the reference protection value parameters.
S206, generating a reference check code corresponding to the reference constant value list through a check code generation algorithm.
In one or more embodiments, the guard values and device parameters in the constant value sheet may generate respective check codes. The check code is obtained by taking a CRC code/national secret SM3 algorithm and taking a constant value list as an algorithm input calculation, and is stored in a transformer substation monitoring system database. By reading the protection fixed value and the device parameter in the fixed value list and calculating the check code according to the CRC algorithm or the SM3 cryptographic algorithm, one fixed value list only generates one check code, and thus, the fixed value list of each protection device has one unique corresponding check code.
S208, storing the reference protection fixed value and the reference check code in a local database.
The reference protection fixed values and the reference check codes stored in the local database are stored as the reference values of the transformer substation, so that the protection fixed values can be quickly found out when the transformer substation is inspected later.
In one or more embodiments of the present application, an overall monitoring flow of a substation protection fixed value monitoring method provided in the present application is shown in fig. 3.
First, the constant value of the protection device 1 is summoned from the man-machine interface.
When the transformer substation setting process is carried out, operation and maintenance personnel can adjust various equipment parameters of the transformer substation, so that the protection fixed value of the transformer substation obtained by calculation in the transformer substation protection device can be changed. At this time, the monitoring background can obtain the protection fixed value and the equipment parameter of the protection device corresponding to the transformer substation from the transformer substation protection device in a wired or wireless communication mode through a human-computer interface.
Next, the protection value of the protection device 1 is generated into a value sheet in a standard format.
And storing the obtained protection fixed value and equipment parameters of the transformer substation in a preset format to obtain a fixed value list.
And generating the check code by the check code generation algorithm from the fixed value list of the protection device 1.
Because the number of the devices of the transformer substations is large, the fixed value list contains hundreds of pieces of data, the fixed value list is substituted into a check code generation algorithm as a whole, the algorithm can acquire a unique check code corresponding to the fixed value list, and each fixed value list of the transformer substations has a corresponding check code. The check code and the fixed value list of each transformer substation are stored in a database of the monitoring background.
And comparing the check code with a reference check code of the protection device 1 in the local database.
If the comparison is consistent, the fixed value list of the protection device 1 is identical to the reference fixed value list of the protection device 1 stored in the local database, and the protection fixed value is not changed. The unchanged result may be displayed directly on the human-machine interface.
If the comparison is inconsistent, it is indicated that there is a difference between the fixed value list of the protection device 1 and the reference fixed value list of the protection device 1 stored in the local database, and thus the protection fixed value in the protection device 1 is necessarily changed. And generating an alarm signal which is used for prompting the codes of the protection device with inconsistent comparison between the check code and the reference check code and requesting to change the protection fixed value of the protection device. The operation and maintenance personnel can select whether the protection fixed value in the current protection device 1 needs to be read or not through the man-machine interaction interface according to the alarm signal, if the protection fixed value needs to be read, the protection fixed value in the protection device 1 is compared with the reference protection fixed value of the protection device 1 stored in the local database, the protection fixed value inconsistent in comparison is obtained, and all the protection fixed values inconsistent in comparison found in comparison are displayed on the man-machine interaction interface. After the detailed data of the protection values are displayed, an operator can decide whether the data needs to be modified.
The operation and maintenance personnel can trace the operation of the man-machine interaction interface.
In one or more embodiments of the present application, referring to fig. 4, a schematic data flow diagram in a substation protection value monitoring method of the present application is shown. From the present data flow diagram, it can be seen that,
the monitoring background comprises a man-machine interface and a data acquisition and control module, wherein the man-machine interface is used for sending a command for calling the protection fixed value to the data acquisition and control module, and the data acquisition and control module is used for sending the command for calling the protection fixed value to the monitored transformer substation protection equipment. The substation protection equipment responds to the instruction of calling the protection fixed value, the protection fixed value is uploaded to the data acquisition and control module, and after the data acquisition and control module is compared with the check codes in the method, the comparison result is uploaded to the human-computer interface for display.
In one or more embodiments, all fixed value data of the specified protection device is summoned through a DL/T860 communication protocol, the current fixed value data is used as input, the check code is calculated, and after confirmation by an operator, the fixed value parameter and the check code are updated and stored in an equal monitoring host database to be used as a new reference value.
Meanwhile, as shown in the figure, the monitoring background can monitor a plurality of transformer substation protection devices at the same time, even if more than 10 transformer substation protection devices are monitored at the same time, only the current fixed value single check code and the reference check code of 10 protection devices are required to be compared, if the protection fixed values in the fixed value single of each device are compared one by one, the consistency comparison times of 10 protection devices can be thousands of times, and therefore the problem that the protection fixed values of the protection devices change is difficult to find in the first time. The application can therefore promote the efficiency of protection definite value monitoring greatly.
Based on the above embodiments, the power station protection fixed value monitoring method provided by the present application mainly includes the following advantages:
1. and according to the fixed value single check code corresponding to the fixed value, quickly finding the condition that the fixed value of the protection device is modified, and alarming.
