Figure 1 The accuracy of basic data can be improved through special management of topological relationship, power generation output and equipment load.

[0003] Data quality, as the basis of data analysis, has a crucial impact on the accuracy of data analysis. In the power system, voltage, current, electricity, power and other measurement data are widely used in business scenarios such as flow calculation, diagnostic analysis, and load capacity analysis.

[0127] For example, for an unconnected medium-voltage public line, a medium-voltage distribution balancing group is constructed using the line and the public transformers, user transformers, medium-voltage power supplies, medium-voltage energy storage and other equipment on the line.

[0128] According to the various types of detailed data, a plurality of interconnected medium-voltage public lines are determined in the power grid, and the interconnected medium-voltage public lines, interconnected medium-voltage public line-related equipment, and measuring points of the interconnected medium-voltage public line-related equipment are combined into a medium-voltage distribution line balancing group;

[0131] In one implementation, the specific high-voltage line includes a Π-connected line and a line with a T-connection; the high-voltage line balance group includes a Π-connected line balance group and a line balance group with a T-connection; the specific high-voltage line is determined in the power grid according to the various types of detailed data, and the specific high-voltage line, the measuring point of the specific high-voltage line, the specific high-voltage line branch equipment and the measuring point of the specific high-voltage line branch equipment are formed into a high-voltage line balance group, including:

[0133] For example, for a Π-connected line, the asset nature of the line is public, the line nature is a main line, the voltage level is 35 kV and above, and the interconnection line type is non-cross-regional. When there is no branch line on the line, a Π-connected line balance group is composed of the main line and the head and end measuring points on the main line.

[0134] According to the various types of detailed data, a line containing a T-contact is determined in the power grid, and the line containing a T-contact, the head end measuring point of the line containing a T-contact, the end measuring point of the line containing a T-contact, the branch line of the line containing a T-contact, and the head end measuring point of the branch line of the line containing a T-contact are combined into a line balancing group containing a T-contact.

[0135] For example, for a line with a T-contact, the asset nature of the line is public, the line nature is a main line, the voltage level is 35 kV and above, and the type of interconnection line is non-cross-regional. The main line and all branch lines (branch lines can be public, dedicated, power grid-connected, and energy storage grid-connected lines), the head-end measuring point and the end measuring point on the main line, and the head-end measuring point on the branch line form a line balancing group with a T-contact.

[0136] The above step 1 includes collecting the grid active power data of multiple pre-built whole-station and whole-line balancing groups;

[0139] Adopting the null value checking method, determining whether there is a power null value in the active power data of the power grid, and when there is a power null value, removing the power null value from the active power data of the power grid, and marking the time point of the power null value;

[0140] For example, power anomaly check mainly includes null value check and jump check; null value check: whether the power is null, if it is null, then the power has a null value.

[0141] Adopting the jump verification method, judging whether there is a power jump value in the active power data of the power grid after removing the power null value according to the preset power jump threshold value;

[0142] When the power jump value exists, the power jump value is removed from the active power data of the power grid, and the time point of the power jump value is marked. The active power data of the power grid after removing the power jump value is used as normal power grid active power data, and the value and time point of the normal power grid active power data are marked.

[0143] For example, the power jump check value calculation formula is:

[0144] Z=power grid active power data÷equipment maximum transmission capacity

[0145] Among them, Z is the power jump verification value corresponding to the active power data of the power grid; if Z is greater than the power jump threshold (the power jump threshold is a manually set value), there is a jump in the active power data of the power grid; the present invention can quickly judge all the active power data of the power grid through the power abnormality verification method, and accurately and quickly distinguish between normal power and abnormal power.

[0146] In one implementation, the power balance algorithm includes: a calculation formula for the average power loss rate of the entire station, a calculation formula for the power balance of the medium voltage distribution line, a calculation formula for the power balance of the Π-connected high-voltage line, and a calculation formula for the power balance of the T-connected high-voltage line; the power balance algorithm described in step 3 above is used to calculate the average power loss rate of the entire station and line balance group corresponding to the abnormal power grid active power data, including:

[0163] In one implementation, the above step 4 uses a power repair algorithm based on the average power loss rate and the grid active power processing value to repair abnormal grid active power data in the whole station and whole line balancing group that meets the specified conditions, including:

[0164] Find out the whole station and whole line balancing group with only one abnormal power grid active power data at the same time as the whole station and whole line balancing group that meets the limited conditions; the whole station and whole line balancing group that meets the limited conditions includes one or more of the following: a whole station balancing group that meets the limited conditions, a medium voltage distribution line balancing group that meets the limited conditions, a Π-connected line balancing group that meets the limited conditions, and a line balancing group containing T-connections that meets the limited conditions;

[0165] For example, a whole station and whole line balancing group that only lacks one power jump value or power null value at the same time can use the power repair algorithm through the average power loss rate and the normal power value to find the power jump value or power null value.

[0166] Based on the average value of the whole-station power loss rate and the active power processing value of the power grid of the whole-station balancing group that meets the limited conditions, the whole-station power repair calculation formula is used to calculate the whole-station power repair value, and the abnormal power grid active power data in the whole-station balancing group that meets the limited conditions is repaired according to the whole-station power repair value;

[0167] Based on the average value of the medium-voltage distribution power loss rate and the grid active power processing value of the medium-voltage distribution balancing group that meets the limited conditions, a medium-voltage distribution power repair calculation formula is used to calculate the medium-voltage distribution power repair value, and the abnormal grid active power data in the medium-voltage distribution balancing group that meets the limited conditions is repaired according to the medium-voltage distribution power repair value;

[0168] Based on the average power loss rate of the Π-connected high-voltage line of the Π-connected line balancing group that meets the limited conditions and the active power processing value of the power grid, a Π-connected high-voltage line power repair calculation formula is used to calculate the Π-connected high-voltage line power repair value, and the abnormal power grid active power data in the Π-connected line balancing group that meets the limited conditions is repaired according to the Π-connected high-voltage line power repair value;

[0169] For example, the calculation formula for the power repair of the Π-connected high-voltage line is as follows:

[0172] Based on the average power loss rate of the T-connected high-voltage line of the line balancing group containing T-connections that meets the limited conditions and the active power processing value of the power grid, a T-connected high-voltage line power repair calculation formula is used to calculate the T-connected high-voltage line power repair value, and the abnormal power grid active power data in the line balancing group containing T-connections that meets the limited conditions is repaired according to the T-connected high-voltage line power repair value;

[0173] For example, the power repair calculation formula for T-connected high-voltage lines is as follows:

[0176] Repeat the above steps until all repairs are completed or there are no new repair values.
