[0045] Embodiment 1

[0046] Figure 1 It is a flowchart of the intelligent substation operation and distribution data acquisition and fusion method based on container technology for Embodiment 1. As Figure 1 shown, the intelligent substation operation and distribution data acquisition and fusion method based on container technology for Embodiment 1 includes the following steps:

[0047] S1: Collect the operation and distribution data of the substation through a unified data interface;

[0048] S2: Preprocess the data using a data parallel preprocessing method based on Spark;

[0049] There are problems of duplicate redundancy and data non-uniformity in the data collected from each system of marketing and power distribution. The present invention uses a data parallel preprocessing method based on Spark to solve the problems, and the main steps are as follows:

[0050] S201: Data dimensionality reduction, data empty / deficiency filling based on the map function and reduce;

[0051] Specifically, it includes the following steps:

[0052] (1) Import the original data into Spark to form a resilient distributed dataset for parallel computing;

[0053] (2) Remove the fields that are invalid for data analysis through feature selection;

[0054] (3) Use the transformer ID of the transformer substation area and the recorded date as the duplicate checking criterion of the map function, and mark the duplicate data records. Use the database operations provided by Spark SQL to merge the data according to the two key fields, and finally return the positions where the number of merged data records is greater than 1. Use the reduce function to delete the corresponding rows in the original array to obtain a new dataset with duplicate data removed.

[0055] (4) Use the map function to calculate the missing ratio of the attributes in a single record, remove the empty records with a missing ratio greater than 30%, and fill in the records with a missing ratio less than 30% through the Lagrange interpolation method.

[0056] S202: Data denoising based on the amplitude-limiting and jitter-eliminating filtering algorithm;

[0057] Specifically, it includes the following steps:

[0058] Determine the maximum allowable deviation value for two samplings of the load data. By comparing the difference between two data in consecutive time slices and judging whether the data error is within the maximum deviation value range. If not, the data in the subsequent time slice needs to be replaced with a reasonable value, which can be a copy of the value at the previous time point or the statistical result of the data record;

[0059] The specific approach in combination with Spark is to first use the map function to check each data record one by one, and then use the reduce function to replace the data records that are greater than the deviation value according to the result of the most recent sampling.

[0060] Among them, the maximum allowable deviation value for two samplings of the load data is determined based on expert experience.

[0061] S203: Screening and removing the outlier records based on K-means clustering;

[0062] Specifically, it includes the following steps:

[0063] (1) Convert the data into a structured DataFrame for easy API calculation;

[0064] (2) Import the Spark MLlib algorithm library and implement the clustering of the load by calling the KMeans function; the hyperparameters of the clustering algorithm are set based on expert experience;

[0065] (3) Delete the unclassified data records according to the clustering results using the drop function.

[0066] Since the Spark ecosystem provides a machine learning algorithm library, the data can be directly analyzed by calling functions provided by Spark through the API without implementing a complex load clustering algorithm through a large amount of code.

[0067] S3: Complete data fusion for the preprocessed data through a unified information model; among them, the construction process of the unified information model is as follows:

[0068] Let the processed data set be X = {x1, x2, x3,..., x n}, and a certain data x k can be expressed as:

[0069] T = {(x1, y1),..., (x k , y k )} ∈ (R n ×y) (1)

[0070] where x i ∈ R n is the input sample, y i ∈ y = R is the output sample, i = 1, 2,..., n to find the real-valued decision quantity g i , and the decision quantity is the regression equation for inferring y from x:

[0071] y = g i = (w·x) + b (2)

[0072] In the formula, w is the weight vector in the R n space; b is the bias vector;

[0073] After introducing the nonlinear mapping of the transformation x = Φ(x) and the kernel function K(x, x') = (Φ(x)·Φ(x')), classification is performed by mapping to a high-dimensional space, and the classification formula can be expressed as:

[0074]

[0075] s.t. y i (w·Φ(xi )) + b + η i , i = 1, 2, …, l (4)

[0076] Where η = [η1, η2, …, η l is the error variable; C is the penalty coefficient. According to the Lagrangian function, we can get:

[0077]

[0078] Where α = [α1, α2, …, α i , …, α l T represents the Lagrange multiplier. According to the KKT optimality conditions, the above formula is differentiated to obtain:

[0079]

[0080] Find a and b according to the least squares method. Let be any solution to the above problem. Then the solution (w * , b * ) can be calculated according to the following formula:

[0081]

[0082]

[0083]

[0084] Normalize the decision-making quantity:

[0085]

[0086]

[0087] Where q i is the consistency coefficient.

[0088] The advantage of the above solution is that the operation and distribution data acquisition and fusion method provided by the present invention can eliminate possible conflicts in data acquisition by each sensor. This method constructs a unified information model to uniformly describe different data, which can effectively avoid the problem of inconsistent data models and the workload of model conversion in data exchange. Since it is unified modeling and unified storage, there is no redundancy in data, and thus there is no need to perform data exchange, comparison, etc. in two sets of systems, greatly reducing the development and maintenance workload.

[0089] S4: Place the fused data in different containers that have been safely isolated according to the task identifier;

[0090] ​Among them, each container has an independent task identification mechanism. When mapping to the integrated terminal kernel, a complete task identification is formed by combining the container identification and the task identification. The operation and maintenance data integration terminal isolates the business software from the operating system through container technology, improving the system security while isolating the power distribution service APP and the power consumption information acquisition service APP.

[0091] Furthermore, the security isolation method between the containers is as follows: construct a set of security isolation policy rules, determine the partitioning method of the object address space according to the set of security isolation policy rules, and different subjects access different address spaces according to different permissions.

[0092] For j, 1 ≤ i ≤ n, 1 ≤ j ≤ n, i ≠ j, there is R(Co i ) ∩ W(Co i ) = φ.

[0093] In the formula, R: S → 2 L represents the object address space where the subject S can perform read operations; W: S → 2 L represents the object address space where the subject S can perform write operations; Co i (1 ≤ i ≤ n) represents the container i subject.

[0094] Among them, according to the set of security isolation policy rules, determine the partitioning method of the object address space;

[0095] The rule set includes:

[0096] Rule 1:

[0097] Rule 2:

[0098] In the formula, H represents the address space corresponding to the objects that the host subject can operate on arbitrarily. Let H x represent the first type of address space in H, H ro represent the second type of address space in H, and H ic (1 ≤ i ≤ n) represent the third type of address space in H.

[0099] Among them, Rule 1 means that the address space where any container i (1 ≤ i ≤ n) subject can perform read operations includes the container address space C i (1 ≤ i ≤ n) corresponding to all objects within the container i, the address space H ro corresponding to the objects that all subjects in H can only perform read operations on, and the object address space H ic (1 ≤ i ≤ n) corresponding to the container i subject in H where reading and writing can be performed.

[0100] Rule 2 states that the address space that the body of any container i (1 ≤ i ≤ n) can write to includes the container address space C corresponding to all the objects within container i i (1 ≤ i ≤ n), and the object address space H in H that only the body of container i can read and write ic (1 ≤ i ≤ n).

[0101] This application proposes an address space partitioning method that meets the restrictive conditions in Rule 1 and Rule 2, that is, different subjects access different address spaces according to different permissions, and it is ensured that all containers in the converged terminal are securely isolated from each other.

[0102] That is, for j, 1 ≤ i ≤ n, 1 ≤ j ≤ n, i ≠ j, there is R(Co i ) ∩ W(Co i ) = (C i ∪H ro ∪H ic ) = (C j ∪H jc ) = φ.

[0103] The method for determining the partitioning of the object address space according to the set of security isolation policy rules is as Figure 2 shown. Create a new container, allocate a container body and a certain range of object address space for the container. The container body can perform any operation on the objects within this address space range in the container, and can initiate a system call to the body according to needs to apply for access to the corresponding address space, and different subjects access different address spaces according to different permissions. Q represents the address space corresponding to all objects. According to the set of security isolation policy rules, the address space corresponding to all objects can be regarded as an (n + 1)-tuple, where n represents the number of containers among the subjects, that is, Q = {H, C1, C2, …, C n}, and the object address space that the subject can operate on arbitrarily can be regarded as an (n + 2)-tuple, that is, H = {H x , H ro , H 1c , H 2c , …, H nc}.

[0104] The advantage of the above solution is that through the partitioning of the container address space, the present invention can effectively isolate the containers so that there is no direct or indirect information exchange between them, and the address space and content written by any other container body cannot be directly read by any one container body, ensuring the security of the data.

[0105] S5: Classify the containers into different security levels, denoted as L.

[0106] To avoid unauthorized communication between containers, the present invention classifies containers into different security levels, where L = {L1, L2, L3, L4, L5, L6, L7}, and the relationships between the levels are as Figure 3 shown:

[0107] In container multi-level access control, each different security level L i contains different containers L i C i , and L i C is denoted as the set of containers included in the L i security level. Then

[0108] L i C = {L i C1, L i C2,..., L i C n} (12)

[0109] And each container has an information L i C i m i . L i C i M is denoted as the set of container information. Then

[0110] L i C i M = {L i C1m1, L i C2m2,..., L i C n m n} (13)

[0111] For each container, the administrator can classify the container into the corresponding security level according to his own needs.

[0112] The subject L i can encrypt the information m through the following relational expression to obtain the ciphertext c:

[0113] c = m e modN i (14)

[0114] If L j is an ancestor of L i , the subject L j can parse the ciphertext c through the following relational expression to obtain the information m:

[0115]

[0116] To ensure data security, for any piece of information m, it is encrypted using K = <e, N>, denoted as [m, K], and defined as:

[0117] [m, <e, N>] = m e mod N (16)

[0118] The encryption key K = <e, N>, and the decryption key K -1 is represented by the ordered pair <d, N> and satisfies ed = 1 mod φ(N).

[0119] For the decryption key K -1 = <d, N>, given the ciphertext c, the plaintext m can be obtained through the following relationship, denoted as [c, K -1 :

[0120] m = [c, K -1 = c d mod N (17)

[0121] For any piece of information m, when K = <e, N> and K -1 = <d, N>, there is

[0122] [[m, K], K -1 = m (18)

[0123] In the multi-level relationship of the container, it is possible to encrypt the information m using the encryption key K provided by the hierarchy, and it is also possible to use the provided decryption key K -1 to decrypt the encrypted information and restore it to the information m.

[0124] Each container has an independent network environment. The tasks within the container communicate with the outside through the network. The container has its own ports, IP addresses, sockets, etc., and can achieve the docking of the marketing and power distribution dual master stations through remote communication methods such as optical fiber or 4G.
