[0002] In the current power system management and operation and maintenance process, calculating the various index values ​​in the power grid is a key link in evaluating the performance of the power grid system and predicting the risk of failure. When calculating the index values ​​in the power grid, the method currently used is to directly obtain the parameter values ​​required for calculating the index values ​​from the database according to the calculation formula, and calculate the index values ​​according to the parameter values ​​to obtain the index values.

[0028] According to an embodiment of the present application, a method for determining a parameter value is provided.

[0029] Figure 1 is a flow chart of a method for determining parameter values ​​according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0030] Step S101, receiving a target calculation instruction, wherein the target calculation instruction is used to instruct calculation of a target index value at a target time in a target power grid.

[0031] Specifically, the target calculation instruction may be a calculation instruction issued by the operation and maintenance end to the processor when a certain indicator value in the power grid needs to be determined. The target calculation instruction may include the target indicator value to be performed and the target power grid where the target indicator value is located. The target indicator value can then be calculated based on the operating data of the lines and equipment in the target power grid.

[0032] For example, the target calculation instruction can be: calculate the total load peak of the power grid in area A. At this time, it is necessary to obtain the real-time operating data parameters of all substations, transmission lines and power plants in the power grid in area A, including but not limited to the real-time load, voltage, current, power factor and power generation output of each site, and conduct comprehensive analysis and calculation to obtain the total load peak of the power grid in area A, and return the calculation results to the operation and maintenance monitoring system.

[0033] Step S102, calling the target function in the function library according to the target calculation instruction, and determining the parameters required to execute the target function to obtain the parameters to be confirmed, wherein the target function is used to calculate the target indicator value.

[0034] Specifically, after receiving the target calculation instruction, it is necessary to obtain the target function for calculating the target index value indicated by the target calculation instruction from the function library, so that the target index value can be calculated according to the target function.

[0035] For example, the objective function may be a preset expression, wherein the expression contains multiple terms, each term includes multiple parameters to be confirmed, and subsequent parameter determination operations may be performed on each parameter to be confirmed that needs to be input in the preset expression in turn, thereby ensuring the accuracy of the parameters in the preset expression.

[0036] Furthermore, after obtaining the objective function, when executing the objective function, it is necessary to input the basic parameter values ​​into the objective function. At this time, the parameters to be confirmed that need to be input into the objective function and the electrical equipment or electrical circuit to which the parameters to be confirmed belong can be obtained, so that the parameter values ​​of the parameters to be confirmed can be further called from the database, and then the target indicator value can be calculated based on the parameter value and the objective function.

[0037] Step S103, determining the electrical equipment to which the parameter to be confirmed belongs, and obtaining the operation information of the electrical equipment at the target time from the database of the electrical equipment, wherein the operation information includes the first measurement value of the parameter to be confirmed in the electrical equipment and the operation status of the electrical equipment.

[0038] Specifically, the electrical equipment may be a secondary equipment of a substation. After determining the electrical equipment to which the parameter to be confirmed belongs, it is necessary to obtain the operating information of the electrical equipment at the target moment when the target calculation instruction is received from a database storing the operating information of the electrical equipment, thereby determining the parameter value of the parameter to be confirmed provided by the electrical equipment based on the parameters and operating status in the operating information, thereby ensuring the accuracy of the parameter value involved in the calculation of the target index value.

[0039] It should be noted that the operating information of the electrical equipment at the target moment has two data, namely, the first measurement value and the operating status value, wherein the operating status value can be used to determine whether the electrical equipment is in a test state at the target moment, and the first measurement value can be the measurement value obtained after the electrical equipment measures the parameter to be confirmed at the target moment. For example, when the parameter to be confirmed is a voltage value, the first measurement value can be the voltage value measured by the electrical equipment at the target moment, such as 220V, thereby obtaining the operating parameter value uploaded by the electrical equipment to the database.

[0040] Step S104: adjusting the first measured value according to the operating state of the electrical device to obtain a parameter value of the parameter to be confirmed.

[0041] It should be noted that since the electrical equipment is in a test state, the electrical equipment still synchronizes the measurement value to the database. Therefore, the first measurement value in the database may be abnormal, but the abnormality is not caused by a device failure. If it is not changed, after the index value is calculated, it is easy to misjudge the index value abnormality as caused by the equipment abnormality, thereby affecting the normal operation of the power grid. Therefore, after obtaining the first measurement value, it is necessary to adjust the first measurement value according to the operating status of the electrical equipment to obtain accurate parameters to be confirmed, so as to ensure the accuracy of the index value calculation when calculating the index value.

[0042] Specifically, after obtaining the operating information, since the operating information includes the operating status and the first measurement value, it is possible to determine whether the first measurement value needs to be adjusted according to the operating status of the electrical equipment, thereby ensuring the accuracy of the parameter value of the parameter to be determined when the parameter to be determined is determined according to the first measurement value.

[0043] For example, when the operating status is normal, the first measurement value can be directly determined as the parameter value of the parameter to be determined. When the operating status is abnormal, the first measurement value can be adjusted according to the operating status and the first measurement value can be changed to a preset measurement value corresponding to the parameter to be confirmed in the target device, thereby obtaining a more accurate parameter value of the parameter to be determined.

[0044] Furthermore, after adjusting the parameter value of the parameter to be determined according to the operating status, the adjusted parameter value can be added to the objective function as the measured value of the parameter to be determined for calculation, thereby ensuring that the objective function calculates the index value according to the adjusted parameter value, thereby ensuring the accuracy of the target index value.

[0045] The method for determining parameter values ​​provided in the embodiment of the present application receives a target calculation instruction, wherein the target calculation instruction is used to indicate the calculation of the target index value at the target time in the target power grid; calls the target function in the function library according to the target calculation instruction, and determines the parameters required for executing the target function to obtain the parameter to be confirmed, wherein the target function is used to calculate the target index value; determines the electrical equipment to which the parameter to be confirmed belongs, and obtains the operation information of the electrical equipment at the target time from the database of the electrical equipment, wherein the operation information includes the first measured value of the parameter to be confirmed in the electrical equipment and the operating state of the electrical equipment; adjusts the first measured value according to the operating state of the electrical equipment to obtain the parameter value of the parameter to be confirmed. The problem of low efficiency of manually adjusting the parameter value in the related art is solved. After determining the parameter to be confirmed, the electrical equipment to which the parameter to be confirmed belongs is determined, and the first measured value in the operating information is automatically adjusted according to the operating information of the electrical equipment, thereby ensuring the accuracy of the parameter value input into the target function for calculation, thereby achieving the technical effect of improving the efficiency and accuracy of adjusting the parameter value.

[0046] In order to ensure the accuracy of the parameter value of the parameter to be confirmed, optionally, in the parameter value determination method provided in the embodiment of the present application, the first measurement value is adjusted according to the operating state of the electrical equipment to obtain the parameter value of the parameter to be confirmed, including: when the operating state is a non-test state, the first measurement value is determined as the parameter value; when the operating state is a test state, the target line in which the electrical equipment is located is obtained, and an alternative bypass connected to the target line is determined; the operating state of the alternative bypass at the target moment is obtained, and the parameter value of the parameter to be confirmed is determined according to the operating state of the alternative bypass.

[0047] Specifically, when the operating state of the electrical equipment is a non-test state, it indicates that the current electrical equipment is in an autonomous operating state and is not subject to human intervention. At this time, the first measurement value of the electrical equipment is the true measurement value, that is, regardless of whether the electrical equipment is in a normal operating state, the first measurement value can represent the current operating parameters of the electrical equipment. At this time, it can be determined that the first measurement value does not need to be adjusted, and the first measurement value can be directly determined as the parameter value of the parameter to be confirmed, thereby ensuring the accuracy of the calculated target indicator value.

[0048] Furthermore, when the operating state of the electrical equipment is a test state, it indicates that the current electrical equipment is subject to human intervention. At this time, although the electrical equipment still transmits data to the database, the transmitted data is not real data but test data. Therefore, it is necessary to adjust the first measurement value collected and transmitted in the test state to ensure the accuracy of the parameter value of the parameter to be confirmed and avoid the inaccurate calculation of the target indicator value due to the testing of the electrical equipment.

[0049] It should be noted that when it is determined that the operating state of the electrical equipment is a test state, when determining the accurate measurement value of the electrical equipment, the target line where the electrical equipment is located can be obtained, and the parameter value of the parameter to be confirmed can be determined according to the operating state of the alternative bypass of the target line, and then the parameter value of the parameter to be confirmed can be determined according to the relevant operating parameters of the alternative bypass, thereby ensuring the accuracy of the parameter value of the parameter to be confirmed.

[0050] It should be noted that the alternative bypass of the target line is an alternative line to the target line, that is, in the power system, when the target line cannot operate normally, the alternative bypass can be used to replace the target line, thereby ensuring the normal operation of the power grid.

[0051] This embodiment determines the operating state of the alternative bypass, so that the measured value of the electrical equipment can be determined by the measured value of the alternative bypass, thereby improving the accuracy of the parameter value of the parameter to be determined.

[0052] In order to improve the accuracy of the parameter value of the parameter to be confirmed, optionally, in the parameter value determination method provided in the embodiment of the present application, determining the parameter value of the parameter to be confirmed according to the operating status of the alternative bypass includes: when the operating status of the alternative bypass is not operating, determining a preset parameter value as the parameter value of the parameter to be confirmed; when the operating status of the alternative bypass is normal operation, determining whether the alternative bypass is used to replace the target line at the target time; when the alternative bypass is used to replace the target line at the target time, obtaining a second measurement value of the parameter to be confirmed from an alternative device in the alternative bypass, and determining the second measurement value as the parameter value of the parameter to be confirmed; when the alternative bypass is not used to replace the target line at the target time, determining the preset parameter value as the parameter value of the parameter to be confirmed.

[0053] Specifically, when determining the parameter value of the parameter to be confirmed according to the operating status of the alternative bypass, when the operating status of the alternative bypass is not operating, it indicates that the alternative bypass is also in a testing or abnormal state. At this time, it can be determined that the measurement values ​​uploaded by the target line and the alternative bypass are inaccurate. At this time, the preset parameter value can be used as the parameter value of the parameter to be confirmed and sent to the objective function to calculate the target index value, thereby ensuring the accuracy of the target index value. The preset parameter value can be 0 or a preset value of the parameter to be confirmed. It needs to be determined here according to the parameter setting method of the parameter to be confirmed, and no limit is set in this application.

[0054] Furthermore, when the operating state of the alternative bypass is normal operation, since the alternative bypass may replace multiple lines including the target line, it is also necessary to determine whether the alternative bypass is used to replace the target line at the target time. When the alternative bypass is used to replace the target line, the second measured value in the alternative bypass can be determined as the parameter value of the parameter to be confirmed, thereby ensuring the accuracy of the parameter value of the parameter to be confirmed.

[0055] Furthermore, when the alternative bypass does not replace the target line but replaces other lines, indicating that the target line is in a test state and there is no alternative line, the preset parameter value is still used as the parameter value of the parameter to be confirmed and sent to the objective function to calculate the target index value, thereby ensuring the accuracy of the target index value.

[0056] Optionally, in the parameter value determination method provided in the embodiment of the present application, after determining the alternative bypass connected to the target line, the method further includes: if no alternative bypass exists for the target line, determining a preset parameter value as the parameter value of the parameter to be confirmed.

[0057] Specifically, when there is no alternative bypass for the target line, the state of the target line at this time is consistent with the state that the alternative bypass does not replace the target line. At this time, the preset parameter value can be directly used as the parameter value of the parameter to be confirmed and sent to the objective function to calculate the target index value, thereby avoiding the use of erroneous measurement values ​​as the parameter values ​​of the parameter to be confirmed, thereby ensuring the accuracy of the target index value.

[0058] In order to ensure that the parameter value of the parameter to be confirmed can be accurately involved in the calculation, optionally, in the parameter value determination method provided in the embodiment of the present application, after adjusting the first measurement value according to the operating state of the electrical equipment to obtain the parameter value of the parameter to be confirmed, the method also includes: judging whether the parameter value of the parameter to be confirmed is a preset parameter value; in the case that the parameter value of the parameter to be confirmed is the preset parameter value, determining the position information of the parameter value in the objective function, and judging whether the parameter value is abnormal based on the position information; in the case that the parameter value is abnormal, sending a prompt message to the operation and maintenance end, wherein the prompt message is used to characterize the existence of abnormal parameters in the objective function.

[0059] Specifically, when the parameter to be confirmed is a preset parameter value, since the preset parameter value is 0, it is necessary to determine the position information of the parameter to be confirmed in the objective function, and determine whether the parameter to be confirmed can be set to the preset parameter value based on the position information, wherein the position information is used to determine whether the parameter to be confirmed is used as the only denominator.

[0060] When the parameter value of the parameter to be confirmed is the preset parameter value and it is determined that the parameter value is abnormal based on the location information, it can be determined that the parameter to be confirmed is the only denominator in the objective function. At this time, it is necessary to send a prompt message to the operation and maintenance section so that the parameter value in the objective function can be adjusted by the staff of the operation and maintenance section to complete the calculation operation of the objective function.

[0061] When the parameter value of the parameter to be confirmed is a preset parameter, and the parameter value is determined to be normal based on the position information, it can be determined that the parameter to be confirmed is not the denominator in the objective function, or is not the only denominator. At this time, the parameter value of the parameter to be confirmed can be determined to be the preset parameter value, and the preset parameter value is added to the objective function, thereby ensuring that the target indicator value can be accurately calculated and that there is no abnormality in the calculation process.

[0062] Optionally, in the parameter value determination method provided in the embodiment of the present application, judging whether the parameter value has an abnormality according to the position information includes: judging whether the parameter value is located at the denominator position; if the parameter value is not located at the denominator position, determining that the parameter value has no abnormality; if the parameter value is located at the denominator position, judging whether the denominator position only contains the parameter value; if the denominator position only contains the parameter value, determining that the parameter value has an abnormality; if there are other parameter values ​​at the denominator position, determining that the parameter value has no abnormality.

[0063] Specifically, when determining whether a parameter value is abnormal, it can be determined by determining the position information of the parameter value in the objective function. First, it is necessary to determine whether the parameter value is located in the denominator position. If it is not located in the denominator position, it is determined that the parameter value is normal, and the preset parameter value can be directly added as the parameter value of the parameter to be confirmed to the objective function for calculation.

[0064] Furthermore, when the parameter value is in the denominator position, it is necessary to further determine whether the preset parameter value is the only denominator. When the preset parameter value is not the only denominator, even if the preset parameter value is 0, it will not affect the normal calculation of the objective function. At this time, the preset parameter value can be directly added as the parameter value of the parameter to be confirmed to the objective function for calculation.

[0065] Furthermore, when the parameter value is in the denominator position and the preset parameter value is the only denominator, the parameter value representing the parameter to be confirmed cannot be the preset parameter value, that is, it cannot be 0. At this time, there is an abnormality in the parameter value, and a prompt message needs to be sent to the operation and maintenance end to inform the operation and maintenance end that the operation of the objective function cannot be performed, so that the operation and maintenance end can determine the parameter value of the parameter to be confirmed and ensure the normal calculation of the objective function.

[0066] Optionally, in the parameter value determination method provided in the embodiment of the present application, the method also includes: when the electrical equipment is performing a test operation, associating the first measurement value uploaded by the electrical equipment to the database with the target identifier; obtaining the operation information of the electrical equipment at the target time from the database of the electrical equipment includes: obtaining the first measurement value uploaded by the electrical equipment to the database at the target time, and determining whether the first measurement value is associated with the target identifier; when the first measurement value is associated with the target identifier, determining that the state of the electrical equipment is a test state; when the first measurement value is not associated with the target identifier, determining that the state of the electrical equipment is an untested state.

[0067] Specifically, in order to conveniently determine the operating status of the electrical equipment when uploading the measurement value, when the electrical equipment is performing a test operation, the first measurement value can be associated with the target identifier when uploading the operating data measurement value of the electrical equipment. Therefore, when the measurement value is obtained from the database, the operating status of the electrical equipment when uploading the measurement value can be determined by judging whether it is associated with the target identifier, thereby judging whether the electrical equipment is in a test state.

[0068] For example, when the first measurement value is obtained, it is detected whether the first measurement value is associated with the target identifier. When the first measurement value is associated with the target identifier, the state of the electrical equipment is determined to be a test state. When the first measurement value is not associated with the target identifier, the state of the electrical equipment is determined to be an untested state, thereby achieving the technical effect of quickly determining the operating state of the electrical equipment based on the measurement value.

[0069] Figure 2 is a flowchart of a method for determining an optional parameter value according to an embodiment of the present application, such as Figure 2 As shown, when there are multiple parameters to be confirmed in the objective function, the parameter value of each parameter to be confirmed can be determined in turn, so that the multiple parameter values ​​are substituted into the objective function, thereby completing the calculation of the target index value through the objective function.

[0070] For each parameter to be confirmed, first obtain the electrical equipment to which the parameter to be confirmed belongs, and determine the operating state of the electrical equipment when uploading the parameter to be confirmed. When the operating state is a non-test state, determine the first measurement value uploaded by the electrical equipment in the database as the parameter value of the parameter to be confirmed. When the operating state is a test state, determine the position of the parameter to be confirmed in the objective function, and judge whether the parameter to be confirmed is the only denominator in the expression of the objective function. When the parameter to be confirmed is not the only denominator in the expression of the objective function, determine the parameter value of the parameter to be confirmed as a preset parameter value, such as 0.
