Description

Technical Field

[0001] This invention patent application belongs to the field of power restoration technology, specifically relating to a method and system for verifying and restoring power grid power. Background Technology

[0002] To deepen the application of online power grids, enhance the support capabilities for business development, improve the efficiency and effectiveness of business development work, and better serve the construction of a new power system, this paper proposes to deepen the monitoring of data quality at the whole-plant, whole-station, and whole-line levels, and to promote data quality monitoring at different voltage levels, while consolidating the application of the "one map" system in all-time scenarios. Figure 1 Specialized governance of topological relationships, power generation output, and equipment load will improve the accuracy of basic data.

[0003] Data quality, as the foundation of data analysis, has a crucial impact on its accuracy. In power systems, measurement data such as voltage, current, energy, and power are widely used in power flow calculations, diagnostic analysis, and load-bearing capacity analysis. However, these data contain numerous anomalies such as missing data and jumps, severely affecting the accuracy of data analysis.

[0004] The existing technologies have the following problems in power repair: (1) Strong dependence on samples: Conventional power repair methods are usually based on historical data or preset rules. Historical data can only reflect past situations. For new operating conditions or abnormal situations, there is a lack of sufficient information support, which leads to poor power repair effect when these methods face new operating conditions or unseen situations; (2) Poor adaptability to sudden events: Traditional methods lack rapid response capability and are difficult to make quick adjustments when sudden events (such as power changes, equipment failures, etc.) occur, resulting in poor power repair effect.

Finally, the substation, its incoming and outgoing equipment (including public lines, user lines, power grid connection lines, energy storage grid connection lines, station capacitors and reactors), and the measuring points associated with the incoming and outgoing equipment are combined into a whole station balancing group. The active power data of the power grid is obtained using the above-mentioned measuring point codes. Therefore, the measuring points are also a component of the whole station and whole line model balancing group.

[0110] Based on the detailed data, a specific medium-voltage public line is identified in the power grid. The specific medium-voltage public line, the associated equipment of the specific medium-voltage public line, and the measuring points of the associated equipment of the specific medium-voltage public line are combined to form a medium-voltage distribution balance group. The specific medium-voltage public line is a medium-voltage public line with public asset nature, large feeder nature, and voltage level of 10 kV or 20 kV.

[0111] For example, the medium-voltage wiring in a medium-voltage wiring balance group is of public use, the line is a large feeder, and the voltage level is 10 or 20 kV. Through the lines belonging to the public transformer, user transformer, medium-voltage power supply, and medium-voltage energy storage, the medium-voltage wiring, public transformer, user transformer, medium-voltage power supply, medium-voltage energy storage, and the measuring points of these devices are combined into a medium-voltage wiring balance group.

[0112] Based on the detailed data, specific high-voltage lines are identified in the power grid. The specific high-voltage lines, their measuring points, branch line equipment, and measuring points of the branch line equipment are then combined to form a high-voltage line balancing group. The specific high-voltage lines are public assets, main lines, with a voltage level of 35 kV and above, and non-inter-regional high-voltage lines.

[0126] Other data includes one or more of the following: power grid topology, switch status (closed, open), and power data at the acquisition point. These data reflect the structure and operation of the power grid and are key inputs for building whole station and whole line models, performing data repair and extrapolation.

[0127] The substation and line balancing group of this invention is constructed by comprehensively considering the operating characteristics of substations and lines as well as the grid structure characteristics of the power grid. Furthermore, the substation and line balancing group updates its parameters in real time based on the operating conditions during operation. Therefore, subsequent power balancing and power repair algorithms reduce reliance on historical data, thereby more accurately predicting and handling new situations. Based on the operating characteristics of substations and lines, the grid structure characteristics of the power grid, and the substation and line operation mechanism, this invention generates a substation balancing group, a medium-voltage distribution balancing group, and a high-voltage distribution balancing group, enabling rapid repair of abnormal active power data in the power grid at the balancing group level.

[0128] In one implementation, the specific medium-voltage public line includes medium-voltage public lines without connections and medium-voltage public lines with connections; the step of determining the specific medium-voltage public line in the power grid based on the various detailed data, and forming a medium-voltage wiring balancing group by assembling the specific medium-voltage public line, the associated equipment of the specific medium-voltage public line, and the measuring points of the associated equipment of the specific medium-voltage public line, includes:

[0129] Based on the detailed data, a non-interconnected medium-voltage common line is identified in the power grid. The non-interconnected medium-voltage common line, the associated equipment of the non-interconnected medium-voltage common line, and the measuring points of the associated equipment of the non-interconnected medium-voltage common line are combined to form a medium-voltage wiring balance group.

[0130] For example, for a non-connected medium-voltage public line, a medium-voltage wiring balance group is constructed using the line and the public transformers, user transformers, medium-voltage power supplies, medium-voltage energy storage and other equipment connected to the line.

[0131] Based on the detailed data, multiple interconnected medium-voltage public lines are identified in the power grid. The interconnected medium-voltage public lines, the associated equipment of the interconnected medium-voltage public lines, and the measuring points of the associated equipment of the interconnected medium-voltage public lines are combined to form a medium-voltage wiring balance group.

[0132] For example, for interconnected medium-voltage public lines, a medium-voltage wiring balance group is constructed by multiple interconnected lines and the public transformers, user transformers, medium-voltage power supplies, medium-voltage energy storage and other equipment connected to the lines.

[0133] The unconnected medium-voltage public utility line associated equipment includes one or more of the following: unconnected medium-voltage public utility line associated public transformer, unconnected medium-voltage public utility line associated user transformer, unconnected medium-voltage public utility line associated medium-voltage power supply, and unconnected medium-voltage public utility line associated medium-voltage energy storage; the connected medium-voltage public utility line associated equipment includes one or more of the following: connected medium-voltage public utility line associated public transformer, connected medium-voltage public utility line associated user transformer, connected medium-voltage public utility line associated medium-voltage power supply, and connected medium-voltage public utility line associated medium-voltage energy storage.

[0134] In one implementation, the specific high-voltage line includes a Π-connected line and a line containing a T-connection; the high-voltage line balancing group includes a Π-connected line balancing group and a line balancing group containing a T-connection; the step of determining the specific high-voltage line in the power grid based on the various detailed data, and forming a high-voltage line balancing group by assembling the specific high-voltage line, the measuring points of the specific high-voltage line, the branch line equipment of the specific high-voltage line, and the measuring points of the branch line equipment of the specific high-voltage line, includes:

[0135] Based on the detailed data, the Π-connection line is determined in the power grid, and the Π-connection line, the starting measuring point of the Π-connection line, and the ending measuring point of the Π-connection line are combined into a Π-connection line balance group.

[0136] 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 tie line type is non-crossing area. When there are no branch lines on the line, a Π-connected line balance group is formed by the main line and the first and last measuring points on the main line.

[0137] Based on the detailed data, lines containing T-connections are identified in the power grid. The lines containing T-connections, their starting and ending measuring points, their branch lines, and the starting measuring points of their branch lines are then combined to form a line balancing group containing T-connections.

[0138] For example, for a line containing a T-connector, 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 tie line type is non-inter-regional, the main line and all branch lines (branch lines can be public, dedicated, power grid connected, energy storage grid connected lines), the beginning and end measuring points on the main line, and the beginning measuring points on the branch lines form a line balancing group containing a T-connector.

[0139] The above step 1 involves collecting power grid active power data from multiple pre-built station and line balancing groups;

[0140] For example, 96 points of active power data of the power grid are collected from the measuring points of each whole station and whole line balancing group. The active power data of the power grid collected from the measuring points of each whole station and whole line balancing group of the present invention is in line with the whole station and whole line operation mechanism of the power grid. The active power data of the power grid collected from the above measuring points can comprehensively detect the active power data of the power grid.

[0141] In one implementation, the power anomaly verification method includes a null value verification method and a jump value verification method; the abnormal power grid active power data includes: power null values ​​and power jump values; step 2 above, using the power anomaly verification method to perform power anomaly judgment on each of the power grid active power data, and determining normal power grid active power data and abnormal power grid active power data, includes:

[0142] The null value verification method is used to determine whether there are power null values ​​in the active power data of the power grid. When power null values ​​exist, the power null values ​​are removed from the active power data of the power grid, and the time point of the power null value is marked.

[0143] For example, power anomaly checks mainly involve null value checks and jump checks; null value checks: whether the power is null, if it is null, then the power has a null value.

[0144] Using the aforementioned jump verification method, based on a pre-set power jump threshold, it is determined whether there are power jump values ​​in the active power data of the power grid after removing power null values;

[0145] 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 taken as the normal active power data of the power grid, and the value and time point of the normal active power data of the power grid are marked.

[0146] Example of power jump check value calculation formula:

[0147] Z = Active power data of the power grid ÷ Maximum transmission capacity of the equipment

[0148] Where Z is the power jump check 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), then there is a jump in the active power data of the power grid; the present invention can quickly judge all active power data of the power grid through the power anomaly check method, and accurately and quickly distinguish between normal power and abnormal power.

[0149] In one implementation, the power balancing algorithm includes: a formula for calculating the average power loss rate of the entire substation, a formula for calculating the power balance of medium-voltage distribution lines, a formula for calculating the power balance of Π-connected high-voltage lines, and a formula for calculating the power balance of T-connected high-voltage lines; step 3 above, which uses the power balancing algorithm to calculate the average power loss rate of the entire substation and line balancing group corresponding to the abnormal power grid active power data, includes:

[0150] When the abnormal power grid active power data comes from the whole station balancing group, the average power loss rate of the whole station corresponding to the abnormal power grid active power data is calculated using the formula for calculating the average power loss rate of the whole station balancing group.

[0151] For example, based on the power balance algorithm, a power balance model was generated, and the average power loss rate of the entire station was calculated as follows:

[0152]

[0153] Among them, P 站平 P represents the average power loss rate of the entire station. 站 P is the sum of the incoming and outgoing power of the substation. 站输入 It is the input power of the entire substation balancing group, that is, the sum of power values ​​less than 0 in the power of the substation's incoming and outgoing lines.

[0154] When the abnormal power grid active power data comes from the medium-voltage distribution balance group, the medium-voltage distribution power balance calculation formula is used to calculate the average value of the medium-voltage distribution power loss rate of the medium-voltage distribution balance group corresponding to the abnormal power grid active power data.

[0155] For example, the power balance calculation formula for medium-voltage wiring is as follows:

[0156]

[0157] Among them, P 中平 P represents the average power loss rate of medium-voltage wiring. 线路 P is the line output power of the medium-voltage distribution balancing group. 电源 P represents the on-grid power of the medium-voltage wiring balance group. 专变 For the dedicated transformer output power of the medium-voltage wiring balancing group, P 储能 P is the energy storage output power of the medium-voltage wiring balance group. 公变 P is the output power of the common transformer in the medium-voltage wiring balancing group. 中输入 The input power of the medium-voltage distribution balancing group is the sum of the power output to the grid, the power supplied to the grid by distributed power sources, the power discharged by energy storage, and the power fed back by public and private transformers.

[0158] When the abnormal power grid active power data comes from the Π-connected line balance group, the Π-connected high-voltage line power balance calculation formula is used to calculate the average power loss rate of the Π-connected high-voltage line of the Π-connected line balance group corresponding to the abnormal power grid active power data.

[0159] For example, the power balance calculation formula for a Π-connected high-voltage line is as follows:

[0160]

[0161] Among them, P Π平 P represents the average power loss rate of the Π-connected high-voltage line. ΠA端 For the power at end A of the π-connected line balancing group, P ΠB端 For the power at terminal B of the Π-connected line balancing group, P Π输入 This refers to the input power of the balancing group of the Π-connected line, which is the power value greater than 0 at both ends of the line.

[0162] When the abnormal power grid active power data comes from the line balance group containing T-connections, the power loss rate of the T-connection high-voltage line in the line balance group containing T-connections corresponding to the abnormal power grid active power data is calculated using the power balance calculation formula for T-connection high-voltage lines.

[0163] For example, the power balance calculation formula for a T-connected high-voltage line is as follows:

[0164]

[0165] Among them, P T平 P represents the average power loss rate of a T-connected high-voltage line. TA端 For the power at end A of the line balancing group containing the T-connector, P TB端 For the power at terminal B of the line balancing group containing the T-connector, P TC端 For the C-terminal power of the line balancing group containing the T-connector, P T输入 The input power of the line balancing group with T-connection is the sum of the power values ​​greater than 0 at each end of the line. The power balancing calculation formula for T-connection high-voltage lines requires calculating the sum of the power at each port, and the power at each port includes one or more of the following: power at end A, power at end B, and power at end C. The power balancing algorithm built by this invention based on the principle of power balancing can learn from a large amount of real-time data, and when there is abnormal active power data of the power grid, it can adaptively adjust the corresponding whole station and whole line balancing group to better cope with new operating conditions and unseen situations, and improve the generalization ability and accuracy of the system.

[0166] In one implementation, step 4 above, based on the average power loss rate and the processed active power value of the power grid, employs a power repair algorithm to repair abnormal active power data in the whole station and whole line balancing group that meets the defined conditions, including:

[0167] Identify the entire station and line balancing group that has only one abnormal power grid active power data at the same time, and use it as the entire station and line balancing group that meets the limiting conditions; the entire station and line balancing group that meets the limiting conditions includes one or more of the following: the entire station balancing group that meets the limiting conditions, the medium voltage distribution balancing group that meets the limiting conditions, the Π-connected line balancing group that meets the limiting conditions, and the line balancing group containing T-connection that meets the limiting conditions.

[0168] For example, in a station-wide line balancing group that is missing only one power jump value or power null value at the same time, the power jump value or power null value is determined by the power loss rate average and the normal power value using a power repair algorithm.

[0169] Based on the average power loss rate of the entire station in the station balancing group that meets the specified conditions and the processed value of the active power of the power grid, the station power repair calculation formula is used to calculate the station power repair value, and the abnormal active power data of the power grid in the station balancing group that meets the specified conditions is repaired according to the station power repair value.

[0170] Based on the average medium-voltage distribution power loss rate and the processed value of the grid active power of the medium-voltage distribution balance group that meets the specified conditions, the 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 balance group that meets the specified conditions is repaired according to the medium-voltage distribution power repair value.

[0171] Based on the average power loss rate of the Π-connected high-voltage lines in the Π-connected line balance group that meets the specified conditions and the processed value of the active power of the power grid, the power repair calculation formula of the Π-connected high-voltage lines is used to calculate the power repair value of the Π-connected high-voltage lines, and the abnormal active power data of the power grid in the Π-connected line balance group that meets the specified conditions is repaired according to the power repair value of the Π-connected high-voltage lines.

[0172] For example, the calculation formula for power repair of a Π-connected high-voltage line is as follows:

[0173]

[0174] Among them, P Π修 For the power restoration value of the Π-connected high-voltage line, P Π1 For the normal active power data of the Π-connected line balancing group, P Π平 This represents the average power loss rate of the Π-connected high-voltage line.

[0175] Based on the average power loss rate of the T-connected high-voltage line in the line balancing group with T-connection that meets the specified conditions and the processed value of the active power of the power grid, the 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 active power data of the power grid in the line balancing group with T-connection that meets the specified conditions is repaired according to the T-connected high-voltage line power repair value.

[0176] For example, the calculation formula for power repair of a T-connected high-voltage line is as follows:

[0177]

[0178] Among them, P T修 P is the power restoration value for the T-connected high-voltage line. T输入 P is the input power of the line balancing group containing T-connectors. T平 P represents the average power loss rate of a T-connected high-voltage line. T负 For a line balancing group containing a T-connector, the power is the sum of negative values, P T1 P is the sum of the power values ​​of the line balancing group containing T-connections, excluding the active power data of abnormal power grids. T2 The sum of negative or zero power values ​​for the line balancing group containing T-connectors.

[0179] Repeat the above steps until all repairs are completed or no new repair values ​​are added.

[0180] The active power processing value of the power grid includes one or more of the following: the input power of the whole station balancing group, the sum of power values ​​other than abnormal active power data in the whole station balancing group, the sum of positive power values ​​in the whole station balancing group, the input power of the medium-voltage distribution balancing group, the sum of negative power values ​​in the medium-voltage distribution balancing group, and the sum of power values ​​other than abnormal active power data in the medium-voltage distribution balancing group and the sum of power values ​​that are negative or 0 in the medium-voltage distribution balancing group. When abnormal active power data of the power grid occurs, the present invention can use a power repair algorithm to quickly adjust and repair the abnormal active power data of the power grid in each whole station and whole line balancing group, thereby reducing the response time.

[0181] In one implementation, the formula for calculating the overall station power restoration is as follows:

[0182]

[0183] Among them, P 站修 P is the power restoration value for the entire station. 站平 P represents the average power loss rate of the entire station. 站输入 P is the input power of the entire station balancing group. 站1 P is the sum of power values ​​other than the abnormal active power data of the power grid in the whole station balancing group. 正和This is the sum of positive power values ​​in the entire station's balancing group.

[0184] In one implementation, the calculation formula for the medium-voltage wiring power repair is as follows:

[0185]

[0186] Among them, P 中修 P is the power restoration value for medium-voltage wiring. 中输入 P is the input power of the medium-voltage wiring balance group. 中平 P represents the average power loss rate of medium-voltage wiring. 负和 P is the sum of negative power values ​​in the medium-voltage wiring balance group. 中1 P1 is the sum of power values ​​other than the abnormal active power data of the power grid in the medium-voltage distribution balance group, and P2 is the sum of power values ​​that are negative or zero in the medium-voltage distribution balance group.

[0187] The objective of this invention is to propose a power restoration method based on the overall operation mechanism of the power grid, employing methods such as... Figure 2 The processing flow shown can accurately repair the power of power grid equipment nodes, solve problems such as null values ​​and jumps at the collection points, and infer the power information of nodes without collection devices, thus achieving a holistic perception of power grid power. This invention proposes a method for accurately repairing the power of power grid equipment nodes, solving data quality problems such as null values ​​or jumps at the collection points, and can also infer the power information of nodes without collection devices, thereby achieving a comprehensive perception of the entire power grid. Based on the source-grid-load-storage (generation side, grid, load side, energy storage) model, this invention constructs a whole-station and whole-line balancing group and performs power repair based on the power balance principle. Through advanced data-driven technology and intelligent algorithms, it can solve the problems of strong sample dependence and poor adaptability to sudden events in conventional power repair methods, thereby improving the accuracy of power repair. This method provides a more efficient, flexible, and intelligent solution for modern power grids. This invention develops a highly efficient power repair algorithm based on the whole-station and whole-line operation mechanism, combining historical data and branch data, and predicting and filling based on the power balance principle. This invention's power repair method based on the whole-station and whole-line operation mechanism of the power grid improves the power repair rate and accuracy of 10 kV and above power grids.

[0188] This invention aims to address the problems of strong sample dependence and poor adaptability to sudden events in existing power restoration methods by constructing a power source-grid-load-storage integrated balancing group and utilizing advanced data-driven technologies and intelligent algorithms. Specific objectives include: improving adaptability and generalization ability: By introducing advanced data-driven technologies and intelligent algorithms, such as power balancing algorithms, this invention enables the system to learn from and adaptively adjust based on large amounts of real-time data.

Reducing dependence on historical data: Through online learning and continuous optimization, the system can continuously update the balancing group parameters during operation, reducing reliance on historical data and thus more accurately predicting and handling new situations. Enhancing rapid response capability: This invention utilizes real-time data acquisition and analysis technology to achieve real-time monitoring of the power grid status. Through adaptive adjustment strategies and closed-loop feedback mechanisms, the system can quickly adjust in the event of sudden events, reducing response time.
